  • J&K Census enumerators raise tech concerns

    Why in the News

    A readiness review for the Population Enumeration phase in Doda district recorded that Census enumerators and supervisors in the snow bound areas of Jammu and Kashmir (J&K) hold mobile devices below the configuration the Census application requires. Census 2027 is India’s first digital headcount, and it runs on personal phones owned by school teachers and government employees rather than on equipment the state issues.

    What is the Digital Census 2027?

    1. First digital enumeration: Census 2027 is the first Census in India to be conducted digitally, with field data captured through a mobile application instead of printed schedules.
    2. Field workforce: Enumerators and supervisors are drawn mostly from school teachers and government employees, who record entries on their own handsets.
    3. Device specification: The application requires a minimum of 8 GB of RAM and Android 13 or above on the device used for Population Enumeration.
    4. Phased design: A self enumeration portal opens before field work, after which enumerators conduct door to door visits within a fixed window.

    What is self enumeration?

    1. Self enumeration: Self enumeration lets a household fill its own Census entries on an online portal instead of waiting for an enumerator to visit. The entry is verified later by the field functionary during the enumeration window.

    Why has device configuration become an enumeration problem?

    1. Hardware shifted to the enumerator: The Census application runs on the enumerator’s personal phone, so the capacity to count depends on assets the state neither owns nor issues.
    2. Specification threshold breached: Functionaries in the snow bound areas of Jammu and Kashmir were found holding phones below the 8 GB RAM and Android 13 requirement.
    3. Cost borne privately: The field workforce is composed of school teachers and government employees, so meeting the specification is a private expense rather than a budgeted input.
    4. Terrain compounds the gap: The affected districts are enumerated ahead of the rest of the country, which leaves the least time to replace or upgrade equipment.
    5. Resolution left open: The review recorded the shortfall for appropriate resolution without naming a procurement or substitution route.

    Why are Ladakh and the snow bound areas enumerated ahead of the rest of the country?

    1. Second phase advanced: The second phase of the Census in Ladakh and the snow bound areas of Jammu and Kashmir, Uttarakhand and Himachal Pradesh is being conducted ahead of the rest of the country.
    2. Weather window: Snowfall closes road access to these habitations, so the field round has to be completed before winter sets in.
    3. Self enumeration first: The self enumeration portal for these regions remains available from 17 August to 31 August.
    4. Field window: Door to door enumeration starts on 1 September and concludes by 30 September 2026.
    5. District level review: Doda district’s readiness for that window was reviewed at the Deputy Commissioner’s Office Complex under the Chief Principal Census Officer.

    How is the exercise being prepared for hard to count populations?

    1. Migratory populations: Special attention was directed to the enumeration of migratory populations, whose movement across the enumeration window produces both omission and double counting.
    2. Tribal communities: Tribal communities were named as a category requiring focused enumeration effort.
    3. Remote forest residents: Residents of remote forest areas were named alongside them, since habitations there fall outside routine administrative contact.
    4. Verification discipline: Enumerators and supervisors were directed to ensure that all entries are properly recorded, verified and cross checked.
    5. Field inspection: Charge officers and supervisors were instructed to conduct regular field inspections and quality checks.
    6. Awareness campaigns: District authorities were asked to intensify awareness campaigns through newspapers, pamphlets, social media and local outreach programmes ahead of enumeration.

    Why is the postponement of the Census in Manipur being demanded?

    1. Deferral sought: The principal Opposition party has sought postponement of the Census exercise in Manipur, citing continuing violence and the displacement of thousands of people.
    2. Displacement scale: Nearly 60,000 people have remained homeless since violence in the State began on 3 May 2023, with many still living in relief camps.
    3. Housing stock destroyed: Over 10,000 houses have been destroyed in the State.
    4. House listing defeated: Accurate house listing of thousands of homeless people living in relief camps is not practicable, so the record would capture a household structure that no longer exists.
    5. Postponement, not cancellation: The demand is for deferral until conditions become conducive, and not for cancellation of the exercise in the State.
    6. Raised in Parliament: The Inner Manipur Lok Sabha member said he had raised the matter in Parliament.

    Does a digital Census widen or narrow the count?

    1. Speed against reach: Digital capture shortens the gap between field entry and tabulation, and it makes the count conditional on device capability in the districts hardest to reach.
    2. Uniform standard on an uneven base: A single minimum specification treats a school teacher in Doda and one in a metropolitan district as equally equipped.
    3. Self enumeration favours the connected: An online portal transfers effort to the household, which advantages literate and connected households and leaves the rest dependent on a field visit.
    4. Displacement defeats the frame: A Census counts people at a usual place of residence, and conflict displacement breaks that anchor before any technology is applied.
    5. Errors travel further: A digital schedule locks an entry into a database at the point of capture, so an unverified record propagates instead of being caught at manual tabulation.

    “[2009] Consider the following statements:

    1. Between Census 1951 and Census 2001, the density of the population of India has increased more than three times.

    2. Between Census 1951 and Census 2001, the annual growth rate (exponential) of the population of India has doubled.

    Which of the statements given above is/are correct?

    (a) 1 only

    (b) 2 only

    (c) Both 1 and 2

    (d) Neither 1 nor 2

  • How India plans to count caste now, and what went wrong earlier

    Why in the News

    The Registrar General of India has settled on an open ended question on caste for the ongoing Census, with no predetermined list of castes supplied to the enumerator. The same method in 2011 returned nearly 46.7 lakh distinct caste names and produced no usable table, which places the design of the question, rather than the decision to count, at the centre of the exercise.

    What is an open ended caste question?

    1. How it works: The respondent states a caste in their own words and the enumerator records that answer as given, with no dropdown list or code frame to select from.
    2. No verification step: The enumerator is duty bound to enter what is stated, including a surname offered in place of a caste name.
    3. Errors become data: A misspelling of the stated name becomes an entry in the caste column in its own right.
    4. The colonial precedent: The same open method was used until the 1931 Census, the last census whose caste data were released.

    Why does an open ended question produce unusable data?

    1. Interchangeable names for one group: Rajput, Thakur, Singh and Kshatriya may be used interchangeably by the same respondent for the same identity.
    2. The same name meaning different groups: Rajput in the Bundelkhand region cutting across Uttar Pradesh and Madhya Pradesh may also refer to the Other Backward Class Lodh community.
    3. Surnames that cross categories: Singh is a surname running across castes and across reservation categories, so it identifies nothing on its own.
    4. Volume without structure: The result is a very large number of entries that may all belong to a single caste, with no rule for collapsing them afterwards.
    5. The 2011 outcome: The open method returned nearly 46.7 lakh distinct caste names, against the 4,147 castes recorded in the last comprehensive caste census of 1931.

    What did the 1931 Census reveal about counting caste?

    1. Caste as a subjective category: The 1931 Census report itself recorded the difficulty of enumerating caste once respondents were free to name their own.
    2. New identities appearing between rounds: Sections of the leather working caste among Dalits in Punjab assumed a new religious identity as Aad Dharmis, meaning people of the original, pre Aryan religion of India.
    3. The scale of that shift: 418,789 persons enumerated themselves as Aad Dharmis, roughly the same number as Christians in Punjab at that time, in a category that did not exist in 1921.
    4. The pattern was not local: Similar names appeared in other regions, including Adi Dravida, Adi Andhras and Adi Karnatakas.
    5. Consolidation to bolster numbers: The report recorded grazier castes combining under the term “Yadava” the Ahirs, Goalas, Gopis, Idaiyans and other milkmen castes, a movement already effective in 1921.
    6. What both moves show: Caste counts respond to claims of new social status and to the arithmetic advantage of a larger group, not only to who people are.

    How did caste enumeration lapse after 1931?

    1. 1941: Caste details were collected but caste was dropped from the final tabulation.
    2. 1951: The government led by the first Prime Minister decided there would be no caste enumeration, in a newly independent India shaped by the ideals of equality and secularism.
    3. 2011: The Socio Economic and Caste Census conducted under the then government failed to produce usable caste data because of open ended enumeration.
    4. The data withheld: The Union government eventually withheld the raw caste data from the 2011 exercise.

    What did the Bihar caste survey show about using a list?

    1. The exercise: A statewide caste survey was ordered by the then Chief Minister of Bihar in 2023.
    2. The administrative choice made: State officials compiled a list of castes for the purpose, on the view that enumerating without a list would create an administrative nightmare.
    3. The contest that followed: Questions were raised after the data were released about how the lists were prepared and about the methodology used.
    4. What it establishes: A list makes tabulation possible and simultaneously makes the list itself the contested object, since inclusion and placement decide entitlement.

    What alternative design do experts propose?

    1. A predetermined list: A former chairman of the Indian Council of Social Science Research, who was a member of the expert committee on Telangana’s caste data, holds that a predetermined list is necessary.
    2. Building on lists that already exist: Scheduled Caste, Scheduled Tribe and Other Backward Class lists are already recognised by the government, so only a similar list of castes in the general category is needed for the list to be exhaustive.
    3. The error trade off: Such a list may still carry a margin of error of about 2 to 3 percent, which is smaller than the error produced by open ended enumeration.
    4. Columns for non identification: Separate columns for “no caste” and “no religion” are needed for people who do not identify with either.
    5. Separate questionnaires by group: Distinct questionnaires are proposed for Scheduled Castes and Scheduled Tribes, because the exclusion each faces differs, untouchability related for the former and physical and geographical isolation for the latter.
    6. No separate schedule for Other Backward Classes: A separate questionnaire is held to be unnecessary for OBCs, since social and educational backwardness would be captured by the Census exercise anyway.
    7. Questions on internal hierarchy: A Valmiki community activist campaigning for sub categorisation holds that the schedule must ask about hierarchies and exclusions within the Scheduled Castes and Scheduled Tribes, since some castes within them are more deprived than others.

    How many caste groups does the state already recognise?

    1. Scheduled Castes: The Ministry of Social Justice and Empowerment lists 1,208 Scheduled Castes, with different castes appearing in the category in different States.
    2. Scheduled Tribes: A Press Information Bureau year end release of 2022 lists exactly 730 Scheduled Tribes.
    3. What the two lists prove: A workable, State specific enumeration frame already exists for the reserved categories, which is why the general category is the only gap in a list based design.
    4. The residual problem: The lists are State specific, so a single national code frame still has to reconcile the same caste appearing in different categories across States.

    Challenges to caste enumeration in the Census

    1. Self declaration cannot be verified: No enumerator can test a stated caste against any record, so the count is a record of claims. e.g. the 1931 appearance of 418,789 Aad Dharmis in Punjab was a reclassification, not a demographic change.
    2. Category and caste are conflated: Respondents answer with a reservation category rather than a caste, which destroys the disaggregation the exercise exists to produce. e.g. an entry of “OBC” or “General” tells the statistical office nothing about the specific community.
    3. State specific lists break national aggregation: The same caste name sits in different categories in different States. e.g. a community listed as OBC in one State appears in the general category in a neighbouring one, so a national total is not additive.
    4. Political stakes shape the answer: Enumeration takes place while reservation and sub categorisation demands are live, which gives groups a reason to consolidate. e.g. the Yadava consolidation of Ahirs, Goalas, Gopis and Idaiyans recorded in 1931 combined several castes into one larger head.
    5. Enumerator discretion at the point of entry: With no code frame, spelling, phrasing and abbreviation decisions rest with the field functionary. e.g. a misspelt surname entered as a caste becomes a distinct caste in the final dataset.
    6. Publication risk: Caste tables invite legal and political contest, which creates an incentive to withhold rather than release. e.g. the raw caste data of the 2011 exercise were never published.
    7. Sub caste invisibility: A single caste head hides sharp deprivation differences within it. e.g. sub categorisation demands within the Scheduled Castes rest on the claim that a few communities capture most of the benefit.

    Conclusion

    The choice of an open ended caste question repeats the design that failed in 2011 and that the 1931 report had already flagged as unstable. A predetermined list built on the existing Scheduled Caste, Scheduled Tribe and Other Backward Class rolls, extended to the general category, is the correction experts have placed on record, along with separate questionnaires for Scheduled Castes and Scheduled Tribes and questions on internal hierarchy. The self enumeration window is currently open, so the question design is close to being frozen. Whether the exercise yields a usable caste table will be settled by the code frame, not by the decision to count.

    “[2009] Consider the following statements:

    1. Between Census 1951 and Census 2001, the density of the population of India has increased more than three times.

    2. Between Census 1951 and Census 2001, the annual growth rate (exponential) of the population of India has doubled.

  • Census 2027 questionnaire notified with 40 questions and India’s first caste enumeration since Independence

    Why in the News

    The Registrar General and Census Commissioner of India notified a schedule of 40 questions for the population enumeration phase of Census 2027 on 14 August, and the schedule went live on 17 August in Ladakh and the snow bound areas of Jammu and Kashmir, Uttarakhand and Himachal Pradesh through a self enumeration portal. The design of a single field decides the value of the whole exercise, since Scheduled Caste and Scheduled Tribe respondents select from a fixed drop down while every other respondent types a caste name into an open field, the same method that produced over 46 lakh caste names in the 2011 Socio-Economic and Caste Census.

    What is the population enumeration phase of Census 2027?

    1. The second of two phases: The Census runs in two stages, a houselisting and housing phase followed by the population enumeration phase that records individual level characteristics.
    2. Scope of the notified schedule: The Registrar General notified 40 questions to be asked during this phase, against 29 questions in the Census 2011 questionnaire.
    3. Thirteen new data fields: The schedule adds 13 new questions or data fields that were not part of the 2011 questionnaire.
    4. Self enumeration route: The schedule was made available through a self enumeration portal, allowing a household to fill its own record rather than wait for an enumerator.
    5. Fields marked mandatory: The data fields in the caste section are marked mandatory, with declining to declare recorded as an option rather than left blank.
    6. Wider than the gazette text: The schedule made available to respondents further expands the data fields notified in the Gazette of India.

    What was the Socio-Economic and Caste Census (SECC) of 2011?

    1. A separate survey, not the Census: The Socio-Economic and Caste Census (SECC) of 2011 was a household survey of deprivation indicators conducted alongside but separately from the decennial Census.
    2. The caste data outcome: Its open field method of recording caste returned over 46 lakh different caste names, and the government has maintained over the last decade that the data were unreliable because of errors in data collection.

    What is the National Population Register (NPR)?

    1. A register of usual residents: The National Population Register (NPR) is a register of persons usually resident in a locality, distinct from a citizens’ register.
    2. Status of the update: The NPR was initially proposed to be updated along with the first phase of the Census, and has been put on the back burner amid opposition over concerns that the data could be used to build a country wide National Register of Citizens (NRC).

    What are the new data fields added to the 2027 schedule?

    1. Parents’ religion, date and place of birth: Under the head Family Particulars, the schedule seeks the religion, date of birth and place of birth up to the village level of both the father and the mother.
    2. Birth outside India recorded: A separate option records the place of birth of the father and mother if either was born outside India.
    3. Religion categories fixed with an escape field: Six religious categories are listed, Hindu, Christian, Sikh, Buddhist, Muslim and Jain, with other religion recordable in a separate column.
    4. Identity document details: The schedule seeks Aadhaar, mobile, voter identity card and driving licence details.
    5. Place of COVID-19 vaccination: A question on the place of COVID-19 vaccination offers two options, within India or outside India.
    6. Overlap with the NPR rehearsal form: The additional questions on parents’ particulars, Aadhaar, mobile, voter identity card and driving licence mirror those asked in the 2019 rehearsal form for the National Population Register.

    How will caste be recorded, and why does the method matter?

    1. A drop down for SC and ST respondents: Scheduled Caste and Scheduled Tribe respondents select their caste from a predetermined drop down menu, which fixes the universe of permissible answers.
    2. An open field for everyone else: Question 10(C) reads, if not SC or ST in this State or Union Territory, enter caste name, leaving the entry entirely to the respondent.
    3. Two additional recorded choices: Besides the caste field, the schedule carries Does not want to declare Caste and No Caste as recordable options.
    4. The first count since Independence: This is independent India’s first caste enumeration, since the last full caste count was conducted in 1931.
    5. Why the asymmetry matters: A closed list produces categories that can be aggregated and compared, while free text produces spelling variants, sub caste names, surnames and gotra entries that cannot.
    6. The objection raised: The principal Opposition party has questioned the open field methodology and alleged that the government has abandoned the caste census it announced on 30 April 2025.

    Why does the open field method invite the 2011 failure?

    1. The precedent is documented: The same open field method in the 2011 SECC returned over 46 lakh caste names for a country whose recognised caste categories number in the thousands.
    2. The government’s own verdict on that data: The administration has maintained consistently over the last decade that the SECC caste data were unreliable because of errors in data collection.
    3. Asymmetric quality by design: SC and ST returns will be clean because they are drawn from a list, while Other Backward Classes and general category returns will carry the full noise of free text.
    4. Post enumeration classification burden: Reconciling millions of free text strings into usable categories becomes a discretionary exercise conducted after the count, not during it.
    5. Policy consequence: The categories that most need reliable numbers for reservation and welfare targeting are precisely the ones the open field leaves unstructured.
    6. Trust consequence: Recording caste as mandatory while leaving its classification unstructured invites the charge that the exercise is being conducted without an intention to use the result.

    Challenges to Census 2027

    1. Migrant and homeless undercount: Circular migrants and street dwelling populations are systematically missed, e.g. the absence of updated migration data after 2011 left ration portability planning during the 2020 lockdown without a reliable base.
    2. Digital self enumeration excludes the least connected: A portal based first phase presumes smartphone access and digital literacy, e.g. only 57 percent of women in India have independent internet access against 72 percent of men.
    3. Enumerator capacity and training: The count relies on schoolteachers deputed for the task with short training, e.g. Booth Level Officers in the Telangana Special Intensive Revision of 2026 were found skipping door to door verification under workload pressure.
    4. Data privacy exposure: Collecting Aadhaar, mobile, voter identity and driving licence details in one record creates a linkable profile, e.g. the Digital Personal Data Protection Act, 2023 carries wide exemptions for State instrumentalities processing such data.
    5. Political contestation over the instrument: State level demands can stall the exercise itself, e.g. a 48 hour shutdown in Imphal in August 2026 demanded a National Register of Citizens before the Census in Manipur.
    6. Delimitation and reservation stakes raise the incentive to misreport: Census figures feed seat readjustment and reservation shares, e.g. Article 82 makes the census the basis for readjusting Lok Sabha seat allocation.
    7. Snow bound and conflict affected areas run on a different clock: A staggered reference date fragments comparability, e.g. Ladakh and the snow bound belts began enumeration in August 2026 while the rest of the country follows later.

    Conclusion

    The value of India’s first post Independence caste count now rests on a design choice rather than on the count itself, since a drop down for Scheduled Castes and Scheduled Tribes and free text for everyone else guarantees two grades of data from a single schedule. The stage reached is definite, the 40 question schedule was notified by the Registrar General and Census Commissioner of India on 14 August 2026, and self enumeration went live on 17 August 2026 in Ladakh and the snow bound areas of Jammu and Kashmir, Uttarakhand and Himachal Pradesh, with the self enumeration window running to 31 August. The next milestone is the extension of population enumeration to the rest of the country, for which the source names no separate date. Unless the free text entries are reconciled against a recognised list, the exercise will reproduce the 46 lakh name problem the government itself called unreliable.

  • Registrar General notifies 40 questions for Phase 2 population enumeration of Census 2027 with 13 new questions and web based self enumeration

    Why in the News

    The Registrar General and Census Commissioner of India notified 40 questions on 14 August for Population Enumeration, the second phase of Census 2027. The expansion from the 29 questions of Census 2011 to 40, including identity document numbers and the place of COVID-19 vaccination, has shifted the debate from how India counts its people to how much personal information a census may record.

    What is the Population Enumeration phase of the Census?

    1. About: It is the second and principal phase of the census, in which every individual present in a household is recorded with their demographic, social and economic particulars.
    2. What precedes it: The first phase, House Listing Operations, records buildings, households and household amenities rather than persons.
    3. Reference date: Every entry relates to a fixed reference moment, so that a person is counted once and only once across the country.
    4. Method of collection: Enumerators canvass each household with a schedule of notified questions, supplemented in this round by a web portal.
    5. Who notifies the questions: The Registrar General and Census Commissioner of India notifies the questionnaire after several rounds of consultation with all ministries.

    What is House Listing Operations?

    1. About: It is the first phase of the census, which lists every building and every household and records the amenities and assets each household holds.
    2. When it was held: For Census 2027 it was conducted from April 2026, and self enumeration was offered before it in June.

    What is the extended de facto method of enumeration?

    1. About: Under this method every person present at a location during the enumeration period is counted at that location, whether or not it is their permanent home.
    2. Why it is used: It prevents both the omission of the homeless and mobile and the double counting of persons who have moved between the two phases.

    What is self enumeration?

    1. About: It allows a household to fill in its own census schedule on an official web portal instead of waiting for an enumerator.
    2. How it is secured: The option is georeferenced, so access is restricted to devices located within the notified area for which it has been opened.

    What changes in the Census 2027 questionnaire?

    1. Total questions: The Population Enumeration schedule carries 40 questions, against 29 questions in the Census 2011 schedule.
    2. New additions: 13 new questions appear that were not part of the 2011 questionnaire.
    3. Family and identity fields: The new set records the spouse’s name, nationality, the particulars of the father and mother, and the permanent address.
    4. Document fields: It records the passport, driving licence, mobile number, Aadhaar number and voter identity number, in each case only if available.
    5. Access and asset fields: It records digital literacy and the number of bank accounts an individual holds.
    6. Health field: It records the place of COVID-19 vaccination.
    7. Caste enumeration: The Population Census will separately enumerate caste, alongside these new data fields.

    What rationale and what safeguards accompany the new data fields?

    1. How the questions were settled: The questions were decided after several rounds of discussion with all ministries, each seeking data for its own planning use.
    2. Only government issued documents: The identity documents sought, meaning Aadhaar, voter identity card, driving licence and passport, are all issued by the government itself.
    3. No account details: Enumerators will record only the number of bank accounts an individual holds, not the account details.
    4. Availability condition: Respondents provide these particulars subject to availability, so absence of a document does not obstruct enumeration.
    5. Statutory confidentiality: All data collected is confidential under the Census Act, 1948.
    6. Practical advice to households: Respondents should write their details down on paper before an enumerator arrives, since 40 questions take longer to answer.
    7. Fraud warning: Fraudsters may seek information in the name of the census, and enumerators carry QR code enabled identity cards whose credentials can be verified.

    How will self enumeration operate in Jammu and Kashmir and Ladakh?

    1. Coverage: The option opens for the entire Union Territory of Ladakh and for the snow bound areas of 16 districts of Jammu and Kashmir.
    2. Sequence of operations: The web portal opens on 17 August, and door to door enumeration begins on 1 September.
    3. Geographic restriction: The option is georeferenced and available only within the snow bound areas themselves.
    4. Effect of that restriction: A resident of a snow bound area such as Gurez who is currently in the plains cannot access the portal.
    5. Uptake in the first phase: More than 6.67 lakh households in Jammu and Kashmir and 7,009 households in Ladakh voluntarily completed self enumeration before House Listing Operations in June.
    6. Counting rule applied: Under the extended de facto pattern, everyone present at a location will be counted there.

    Why does Census 2027 carry particular significance for the two Union Territories?

    1. First count after the constitutional change: It will provide the first comprehensive demographic picture of Jammu and Kashmir after the abrogation of Article 370.
    2. First count of a new Union Territory: It will be the first Census of Ladakh as a Union Territory.
    3. Length of the gap: It updates population figures after a gap of more than a decade.
    4. Range of data generated: It will generate data on population distribution, migration, age structure, housing, education, employment, fertility, disability and social composition.
    5. Administrative use: That data feeds planning and resource allocation for two administrations without a recent baseline.
    6. Why geography is the focus: Demographic realities vary sharply across urban centres, border districts, remote mountain villages and tribal areas, so the census aims to capture where people live, how they live and how those patterns are changing.

    What makes enumeration in these two Union Territories difficult?

    1. Dispersed settlement in Jammu and Kashmir: The population is spread across cities, villages, mountainous regions, border areas and tribal habitations.
    2. Seasonal migration: Movement between summer and winter settlements complicates the fixing of a household’s location.
    3. Altitude and terrain in Ladakh: The population lives across a vast high altitude region marked by dispersed settlements.
    4. Connectivity and access: Difficult connectivity, seasonal accessibility and remote locations restrict when and how enumerators can reach households.
    5. The accuracy requirement: The exercise must capture not only headcount but the way population distribution varies across these terrains.

    How will nomadic and displaced populations be counted?

    1. Inter departmental coordination: Special coordination with the departments dealing with forests, tribal affairs and local administration will identify migratory routes and seasonal settlements.
    2. Nomadic communities: The routes and seasonal settlements of the Gujjar-Bakarwals and other nomadic groups will be mapped before enumeration.
    3. The stated objective: Mobility must not translate into undercounting.
    4. Displaced communities: Kashmiri Pandits will be recorded according to established Census concepts and reference dates.
    5. What is captured for them: Their migration history and household characteristics will be recorded alongside the standard schedule.

    Challenges to Census 2027

    1. Undercounting of mobile populations: Pastoral and migrant groups move between the reference date and the enumeration window. e.g. Gujjar-Bakarwal families move to high altitude summer pastures in the Pir Panjal and Ladakh ranges precisely during the enumeration months.
    2. Privacy exposure from identity fields: Recording Aadhaar, voter identity, passport and mobile numbers against a household creates a re identification risk if any downstream database is compromised. e.g. successive breaches of health and telecom databases in India have shown how linked identifiers enable profiling.
    3. Impersonation and cyber fraud: The census provides cover for fraudsters seeking financial credentials. e.g. callers posing as enumerators have previously sought Aadhaar and bank details during welfare verification drives.
    4. Enumerator capacity and quality: Enumeration is done by government employees deployed on top of their regular duties. e.g. schoolteachers form the bulk of enumerators, which interrupts academic schedules and limits training time.
    5. Digital divide in self enumeration: The portal presumes a smartphone, connectivity and literacy in the interface language. e.g. snow bound districts of Jammu and Kashmir carry among the lowest mobile internet reliability in the country.
    6. Delay in the decennial cycle distorts planning: Entitlements calculated on outdated population figures under count beneficiaries. e.g. National Food Security Act, 2013 coverage has continued to use Census 2011 population figures despite population growth since.
    7. Caste enumeration classification: Recording caste requires a settled list of categories and spellings across states. e.g. the 1931 Census recorded over 4,000 caste entries, and Bihar’s 2023 state survey used a far shorter list of 214 categories.

    Conclusion

    Population Enumeration begins on 17 August in Ladakh and the snow bound areas of Jammu and Kashmir, Himachal Pradesh and Uttarakhand and runs till 30 September, ahead of the rest of the country, which will be enumerated in February 2027. Self enumeration on the web portal opens the same day, and door to door enumeration in these areas begins on 1 September. The exercise will produce the first full demographic account of Jammu and Kashmir since the constitutional change of 2019 and the first Census of Ladakh as a Union Territory.

    The Census in India

    1. About: The census is the complete enumeration of every person in the country at a fixed reference moment, together with their demographic, social and economic characteristics.
    2. Administering body: The Office of the Registrar General and Census Commissioner of India, set up in 1961, functions under the Ministry of Home Affairs and conducts the census, the Civil Registration System and the Sample Registration System.
    3. Two phase structure: Every census is conducted in two phases, House Listing Operations followed by Population Enumeration.
    4. Scale: It is the largest peacetime administrative exercise in the world, deploying around 34 lakh enumerators and supervisors to cover more than 1.4 billion people.
    5. Historical continuity: India has conducted a census every ten years since 1881 without interruption until the 2021 round was postponed.
    6. What is new in 2027: Census 2027 will be the first digital census, using a mobile application and a self enumeration portal, and the first to enumerate caste since 1931.
    7. Why the numbers matter: Census figures determine delimitation of constituencies, the population criterion in the Finance Commission’s devolution formula, reservation of seats, and the coverage of welfare entitlements.

    Constitutional Provisions Related to the Census

    1. Entry 69, Union List, Seventh Schedule: Places census exclusively within the legislative competence of Parliament.
    2. Article 246: Distributes legislative power between the Union and the States across the three Lists, which is what makes Entry 69 a Union subject.
    3. Article 81: Fixes the composition of the Lok Sabha and requires seats to be allotted to States in proportion to population.
    4. Article 82: Requires readjustment of the allocation of Lok Sabha seats and the division of States into constituencies after every census.
    5. Article 170: Requires the same readjustment for State Legislative Assemblies after every census.
    6. Article 55: Uses population figures in computing the value of votes in the presidential electoral college, with the 84th Amendment fixing the 1971 figures for this purpose.
    7. Articles 330 and 332: Base the reservation of seats for Scheduled Castes and Scheduled Tribes in the Lok Sabha and State Assemblies on their population share.
    8. Articles 243D and 243T: Base reservation of seats in panchayats and municipalities on population proportions drawn from census data.

    Laws and Rules Governing the Census

    1. Census Act, 1948: Provides the legal authority to conduct a census, appoint census officers and require the public to answer questions.
    2. Section 8: Places a legal obligation on every occupier and every person to answer census questions truthfully.
    3. Section 15: Makes census records confidential, not open to inspection and inadmissible as evidence in any legal proceeding, so an individual’s return cannot be used against them.
    4. Census Rules, 1990: Lay down the procedural framework for appointment of census staff, canvassing and record keeping.
    5. Registration of Births and Deaths Act, 1969: Establishes the Civil Registration System administered by the same Registrar General, which supplies continuous vital statistics between censuses.
    6. Citizenship Act, 1955 and the Citizenship (Registration of Citizens and Issue of National Identity Cards) Rules, 2003: Provide for the National Population Register, a separate register of usual residents, distinct in law from the census.
    7. Collection of Statistics Act, 2008: Governs other official statistical collections and their confidentiality obligations.

    Back2Basics: Census Act, 1948

    1. Enactment: Passed in 1948 and extending to the whole of India, it is the permanent statutory basis for every decennial census.
    2. Trigger: The Central Government notifies its intention to take a census, and the dates, through a gazette notification.
    3. Machinery: It provides for the appointment of a Census Commissioner, Directors of Census Operations, and census officers down to the enumerator level, with defined powers to ask questions.
    4. Public obligation: Every person is legally bound to answer the questions put to them truthfully, and refusal or a false answer is punishable.
    5. Confidentiality guarantee: Individual records are not open to public inspection and are inadmissible as evidence, so census data cannot be used for enforcement against any individual.
    6. Penalties: The Act penalises both a census officer who discloses information and a respondent who gives a false answer.
    7. Nature of the data: Only aggregated statistical tables are published, never individual returns.

    Government Initiatives Related to Population Data

    1. Census 2027 digital application and monitoring portal: Enumeration, supervision and data validation move to a mobile application backed by a central management and monitoring system, replacing paper schedules.
    2. Self Enumeration portal: Allows households to complete their own census schedule online, with georeferencing to restrict access to the notified area.
    3. National Population Register: A register of usual residents maintained under the Citizenship Act, 1955, first prepared alongside the 2011 House Listing phase and updated in 2015.
    4. Civil Registration System: Continuous compulsory registration of births and deaths under the 1969 Act, providing vital statistics between census years.
    5. Sample Registration System: A large scale sample survey run by the Registrar General that generates annual birth rate, death rate and infant mortality estimates.
    6. National Family Health Survey: Conducted under the Ministry of Health and Family Welfare, it supplies fertility, nutrition and health indicators that complement census counts.
    7. Census data portals: Census tables are published for public use through the official census portal and the National Data and Analytics Platform.

    Key Facts about the Census

    1. The first census in India was conducted in 1872 under Lord Mayo, and was non synchronous across provinces.
    2. The first synchronous and complete census was held in 1881 under Lord Ripon, and the decennial series has run from that year.
    3. Census 2011 was the 15th census since 1872 and the 7th after Independence, recording a population of 121.09 crore, a density of 382 persons per square kilometre, a sex ratio of 943 and a literacy rate of 74.04 percent.
    4. Census 2027 will be the 16th census, the first digital census, and the first to enumerate caste since 1931.
    5. The reference date for Census 2027 is 1 March 2027 for most of the country, and 1 October 2026 for snow bound and non synchronous areas.
    6. The Office of the Registrar General and Census Commissioner of India was set up in 1961 and works under the Ministry of Home Affairs.
    7. Census figures govern delimitation, which stands frozen under the 84th and 87th Constitutional Amendments until the first census taken after 2026.

    Challenges in Census Taking in India

    1. Disruption of the decennial cycle: A postponed census leaves every population dependent policy working on stale figures. e.g. the 2021 round was deferred and India will have gone sixteen years between full counts.
    2. Undercount of the homeless and of migrants: Persons without a fixed dwelling are systematically missed. e.g. Census 2011 recorded about 17.7 lakh homeless persons, a figure civil society organisations widely regard as an undercount.
    3. Classification difficulties in caste enumeration: Caste names vary by spelling, region and sub group, which makes tabulation contested. e.g. the 1931 Census produced over 4,000 caste entries that could not be aggregated cleanly.
    4. Urban definition problems: Statistical and administrative definitions of urban areas diverge. e.g. census towns satisfy the census definition of urban but continue to be governed by rural panchayats without urban service standards.
    5. Enumerator burden and data quality: Enumerators are serving government staff performing census duty in addition to their jobs. e.g. schoolteachers form the bulk of the enumerator pool, which limits training depth and interrupts teaching.
    6. Data security in a digital census: Digitised individual level records create risks that paper schedules did not. e.g. a mobile application that stores identity numbers requires encryption and access control standards that do not exist in the Census Act, 1948.
    7. Political sensitivity of population figures: Census numbers directly determine seats and money, which makes them contested. e.g. southern States have objected to the use of current population for delimitation on the ground that it penalises successful fertility decline.

    Way Forward

    1. Legislate a data protection layer over census data: Extend explicit statutory protection to digitally stored individual records, since the Census Act, 1948 predates digital collection.
    2. Publish a clear separation between the Census and the National Population Register: State in the notification itself that census returns cannot be transferred to any citizenship or enforcement register.
    3. Expand assisted self enumeration: Provide common service centre and panchayat level assistance so that self enumeration does not exclude those without smartphones.
    4. Build a special enumeration protocol for mobile groups: Fix pastoral and nomadic enumeration to the migration calendar rather than the general schedule.
    5. Restore and legally fix the decennial cycle: Commit to a statutory timetable so that welfare, devolution and delimitation are never based on a sixteen year old count again.
    6. Standardise the caste enumeration schema in advance: Publish a national list of caste categories and their state variants before enumeration begins to make tabulation usable.
    7. Release disaggregated data quickly: Publish primary census abstracts and district level tables within a fixed period after enumeration so that planning use is not delayed further.

  • Registrar General notifies 40-question Census schedule with caste enumerated beyond SC and ST

    Why in the News

    The Registrar General and Census Commissioner of India has notified the 40 question schedule for the population enumeration phase of Census 2027, with caste recorded as an open declaration for the first time in independent India outside the Scheduled Castes and Scheduled Tribes. The notification exposes two tensions. An open caste column stands against the State wise lists prepared in advance for recent State caste surveys, and eight identity fields drawn from the 2020 National Population Register schedule now sit inside an exercise conducted under the Census Act, 1948.

    What is the population enumeration schedule of Census 2027?

    1. About: The schedule is the questionnaire that census officers are legally authorised to put to every person residing in their assigned area.
    2. Issuing authority: It was notified by the Ministry of Home Affairs under the Census Act, 1948, on the authority of the Registrar General and Census Commissioner of India.
    3. Instrument of collection: Information is gathered through the household schedule, which records the particulars of every person residing in a household.
    4. Size: Census 2027 carries 40 questions against the 29 questions of the Census 2011 questionnaire.
    5. Placement in the exercise: The Census runs in two phases, Housing and House Listing Operations followed by Population Enumeration, and this schedule governs the second phase.
    6. The caste field: Question number 10 reads Scheduled Caste (SC), Scheduled Tribe (ST), Caste, and the enumerator records the caste as declared by the respondent.

    What is the National Population Register (NPR)?

    1. About: The NPR is the register of usual residents of the country, which is distinct from a register of citizens.
    2. Legal basis: It is prepared under the Citizenship (Registration of Citizens and Issue of National Identity Cards) Rules, 2003, framed under the Citizenship Act, 1955.

    What is the National Register of Indian Citizens?

    1. About: It is a register of citizens prepared by verifying the entries already recorded in the Population Register.
    2. Local tier: The Local Register of Indian Citizens holds the verified particulars of persons within the jurisdiction of a Local Registrar.

    What is the Socio Economic and Caste Census (SECC) 2011?

    1. About: The SECC was a household survey of socio economic status and caste conducted alongside Census 2011.
    2. Statutory position: It was run as a survey outside the purview of the Census Act, 1948, carried no statutory backing, and its caste data were never released by the government.

    What are Housing and House Listing Operations?

    1. About: This is the first phase of the Census, which lists every building and household and records housing conditions and household assets.
    2. Current status: The phase is due to end on 30 September and has been completed in most States except West Bengal, Assam and Manipur.

    What is a reference date in a Census?

    1. About: The reference date is the fixed instant to which every entry relates, so a person is counted by their situation at that moment rather than on the day the enumerator visits.
    2. Dates notified: It is 12 a.m. on 1 October for the areas enumerated early and 12 a.m. on 1 March 2027 for the rest of the country.

    What is self enumeration in the Census?

    1. About: Self enumeration allows a household to fill its own schedule through a digital application before any enumerator visit.
    2. Window notified: The option is available from 17 to 31 August, before house to house population enumeration begins.

    Who is the Registrar General and Census Commissioner of India (RG&CCI)?

    1. About: The RG&CCI is the authority under the Ministry of Home Affairs that conducts the Census and notifies the questions census officers are authorised to ask.
    2. Other charge: The same office runs the Civil Registration System and the Sample Registration System.

    What are the new or modified questions in the Census 2027 schedule?

    1. Spouse name: The name of the respondent’s spouse is recorded for the first time.
    2. Nationality as declared: Nationality is recorded as stated by the respondent.
    3. Father’s particulars: Details of the respondent’s father are recorded.
    4. Mother’s particulars: Details of the respondent’s mother are recorded.
    5. Scheduled Caste, Scheduled Tribe, Caste: The existing SC and ST question is modified to add an open caste field.
    6. Literacy and digital literacy: Digital literacy is added to the existing literacy question.
    7. Highest educational level attained and stream or discipline: The stream or discipline of study is recorded along with the level attained.
    8. Place of COVID 19 vaccination: The place where the person received a COVID 19 vaccine is recorded.
    9. Total number of bank accounts: The count of bank accounts held is recorded.
    10. Mobile number: The mobile telephone number is recorded where available.
    11. Aadhaar number: The Aadhaar number is recorded where available.
    12. Voter ID number: The voter identity card number is recorded where available.
    13. Passport number: The passport number is recorded for Indian passport holders.
    14. Availability of driving licence: Whether the person holds a driving licence is recorded.
    15. Permanent residential address: The permanent residential address is also listed among the fields added for the first time.
    16. Scale of the change: Thirteen questions or data fields are entirely new against the 29 question Census 2011 schedule, and 14 questions are new or modified when the caste field is counted as a modification.

    Which of these questions were also part of the 2020 NPR schedule?

    1. Nationality as declared: Declared nationality was sought in the NPR schedule notified in 2020.
    2. Father’s particulars: Particulars of the father were part of the same NPR schedule.
    3. Mother’s particulars: Particulars of the mother were part of the same NPR schedule.
    4. Mobile number: The mobile number was collected under the NPR schedule.
    5. Aadhaar number: The Aadhaar number was collected under the NPR schedule.
    6. Voter ID number: The voter identity card number was collected under the NPR schedule.
    7. Passport number: The passport number was collected under the NPR schedule.
    8. Driving licence: Availability of a driving licence was collected under the NPR schedule.

    Why does an open caste column divide opinion against a list prepared in advance?

    1. The method notified: The enumerator records the caste as declared by the respondent, because the field is an open column with no fixed set of options.
    2. Evidence from the pre test: The pre test for population enumeration ran from 1 to 20 July in 16 States and Union Territories, where respondents outside the reserved categories recorded caste in an open column.
    3. The alternative sought: The Congress general secretary stated that the caste question was widely expected to carry a State wise list prepared in advance, as in the Bihar and Telangana caste surveys, with the response merely ticked.
    4. Charge on intent: The absence of such a list has been described as raising serious doubts on intent.
    5. Record of the open column: The same method in the 2011 SECC returned over 46 lakh different caste names, largely owing to differences in what people understand by caste.
    6. Historical benchmark: The 1931 Census, the last to enumerate caste, recorded 4,147 castes.
    7. Government position: The 2011 SECC caste data have been held over the last decade to be unreliable because of errors in data collection.

    How does the overlap with the NPR schedule reopen the citizenship question?

    1. Statutory link: The Citizenship Rules, 2003 provide for preparation of a Population Register and envisage its verification for preparation of the National Register of Indian Citizens.
    2. Doubtful entries: Rule 4 provides for marking the particulars of individuals whose citizenship is considered doubtful during verification, for further inquiry.
    3. Parental birth details: The 2020 NPR schedule sought the date and place of birth of a person’s father and mother, including district and State, and the country of birth where they were born outside India.
    4. The earlier controversy: Opposition parties and civil society groups argued in 2019 and 2020 that the NPR was a precursor to a nationwide NRC and that parental birth details could later be used to determine citizenship.
    5. State resistance: Several Opposition ruled States passed resolutions opposing the NPR exercise.
    6. Political amplification: The Union Home Minister had repeatedly spoken of a nationwide NRC and sought to link it with the Citizenship Amendment Act through a stated chronology.
    7. Assurance on record: The Prime Minister said in December 2019 that the government had not taken any decision to conduct the NRC, and the Home Ministry reiterated that position on several occasions.
    8. Present position: The Census questions return without any notification for an NPR and without any announced decision to undertake a nationwide NRC.

    What is the current status of the NPR exercise?

    1. First collection: NPR data were first collected in 2010, along with the houselisting phase of the 2011 Census.
    2. Update: The register was updated through a door to door exercise in 2015.
    3. Revival: The Registrar General revived the NPR through a notification in August 2019, to be carried out with the houselisting phase of the 2021 Census.
    4. Postponement: That exercise was postponed because of the COVID 19 pandemic.
    5. Budget provision: The Union Budget 2026 to 2027 allocated Rs 6,000 crore under the head Census, Survey and Statistics and Registrar General of India, for Census 2027 and the NPR.
    6. No fresh notification: The houselisting phase was notified for 1 April to 30 September and made no mention of the NPR, and no fresh NPR exercise has been notified.
    7. Official explanation: A Home Ministry official stated that the allocation followed provisions made in previous budgets since 2020, to keep funds available if and when the government decides to conduct the NPR.

    How is Census 2027 being sequenced across the country?

    1. Early start: Population enumeration begins on Monday in Ladakh and the snow bound areas of Jammu and Kashmir, Uttarakhand and Himachal Pradesh.
    2. Rest of the country: Enumeration in the remaining States and Union Territories will take place in February 2027.
    3. Self enumeration window: The self enumeration option runs from 17 to 31 August, before house to house enumeration starts.
    4. Reference dates: The count relates to 12 a.m. on 1 October for the early areas and to 12 a.m. on 1 March 2027 for the rest of the country.
    5. First phase status: Housing and House Listing Operations end on 30 September and are complete in most States except West Bengal, Assam and Manipur.
    6. Historical marker: This is the first Census since 1931 to enumerate caste and the first in independent India to record caste beyond the Scheduled Castes and Scheduled Tribes.

    Challenges to caste enumeration in Census 2027

    1. Uncontrolled caste nomenclature: An open column accepts whatever name a respondent offers, so sub castes, gotras, sect names and surnames enter the record as separate castes. e.g. the 2011 SECC returned over 46 lakh caste names against the 4,147 castes recorded in the 1931 Census.
    2. No mapping to State lists: Names collected without a State list cannot be matched to State Other Backward Classes schedules that decide reservation benefits. e.g. Bihar’s 2023 caste survey worked from a fixed list of 214 castes, which allowed direct tabulation of shares.
    3. Enumerator discretion in the field: Recording is left to a field enumerator, usually a school teacher, with limited training in caste classification. e.g. the 2011 SECC required years of post survey classification by an Expert Group and still yielded data the government declined to release.
    4. Privacy exposure of identity numbers: Aadhaar, voter identity, passport and mobile numbers create a single linked identity record collected by a field officer. e.g. the Supreme Court in K.S. Puttaswamy versus Union of India (2017) required legality, legitimate aim and proportionality for any state collection of personal data.
    5. Association with citizenship verification: Eight fields repeat the NPR schedule that triggered protests in 2019 and 2020, which raises the risk of non response in minority and migrant households. e.g. several Opposition ruled State assemblies passed resolutions against the NPR in 2020.
    6. Operational strain of a longer schedule: Forty questions against 29 lengthens every household visit and raises enumerator fatigue and transcription error. e.g. the first phase is still incomplete in West Bengal, Assam and Manipur with six weeks left on the notified deadline.
    7. Contestation of the published count: Caste totals feed directly into claims on reservation, so each figure becomes a subject of political dispute. e.g. Bihar’s survey finding that Extremely Backward and Backward Classes form about 63 percent of the State’s population immediately produced demands to breach the 50 percent ceiling.

    Conclusion

    The notification settles the method of the caste count and leaves its reliability open. An open column repeats the design that produced 46 lakh caste names in 2011, and eight identity fields carry the NPR schedule into a statutory Census that no NPR notification accompanies. Population enumeration begins on Monday in the snow bound areas, with the rest of the country following in February 2027.

    Population Data Systems in India

    1. About: India measures its population through one complete decennial count, one continuous registration system, and a set of large sample surveys that fill the years between counts.
    2. Census: The Census is a complete headcount conducted since 1872 and synchronously since 1881, and it has run every ten years without interruption until the 2021 round was postponed.
    3. Civil Registration System: The system continuously records births and deaths under the Registration of Births and Deaths Act, 1969, through State registrars.
    4. Sample Registration System: This large scale sample survey supplies annual estimates of birth rate, death rate and infant mortality rate between two Censuses.
    5. National Population Register: The NPR is a register of usual residents maintained under the Citizenship Rules, 2003, and is not a statistical product.
    6. Sample surveys: The National Sample Survey and the National Family Health Survey supply consumption, employment and health estimates that draw their sampling frames from the Census.
    7. Digital shift: Census 2027 is the first Census to be conducted digitally, using a mobile application for enumerators and a self enumeration portal for households.

    Key Facts about the Census of India

    1. First post Independence census: The first census of independent India was conducted in 1951.
    2. Phases of Census 2011: House Listing Operations ran from April to September 2010 and Population Enumeration from 9 to 28 February 2011.
    3. Population recorded in 2011: The count stood at 121,08,54,977 persons.
    4. State extremes in 2011: Uttar Pradesh was the most populous State, Sikkim the least populous, Kerala recorded the highest literacy and Bihar the lowest.
    5. Density extremes in 2011: Bihar recorded the highest density among States at 1,106 persons per square kilometre and Arunachal Pradesh the lowest at 17.
    6. Frozen delimitation: Lok Sabha seat allocation remains fixed on the 1971 Census until the first census taken after 2026.
    7. Observance: World Population Day is observed on 11 July every year.

    Challenges in India’s Population Data System

    1. Delay in the decennial count: A postponed Census leaves the country without a fresh headcount for far longer than the ten year cycle allows. e.g. the 2021 Census was deferred and the next reference date is 1 March 2027, a gap of sixteen years.
    2. Outdated policy denominators: Welfare entitlements are calculated on population shares that are more than a decade old. e.g. National Food Security Act, 2013 coverage still rests on 2011 population, and estimates placed before the Supreme Court in 2021 put the excluded number at about 10 crore people.
    3. Under registration of births and deaths: Incomplete civil registration prevents the Census from being cross checked against a continuous record. e.g. excess mortality during the COVID 19 pandemic could not be settled because registration completeness varied sharply across States.
    4. Weak measurement of migration: The Census captures migration by last residence and misses seasonal and circular movement. e.g. the 2011 Census counted about 45.6 crore internal migrants, yet in 2020 no State held a usable register of returning migrant workers.
    5. Caste data gap: The absence of a modern caste count forces policy to rely on pre Independence figures. e.g. the Mandal Commission derived its estimate of Other Backward Classes at about 52 percent from the 1931 Census.
    6. Data privacy architecture: Collection of identity numbers by a field officer proceeds without an independent oversight body in place. e.g. the Digital Personal Data Protection Act, 2023 permits the Centre to exempt State instrumentalities from key obligations by notification.
    7. Delayed release and access: Long gaps between collection and release reduce the value of the data for planning. e.g. SECC 2011 caste data were never released at all.

    Way Forward

    1. Publish a State wise caste directory: Prepare and release a standardised caste list for each State before tabulation, so open column returns can be mapped consistently.
    2. Legislate a fixed census calendar: Amend the Census Act, 1948 to bind the Centre to a stated reference date and a stated release schedule for each decennial round.
    3. Separate the statistical count from citizenship registers: Notify expressly that data collected under the Census Act, 1948 will not be used to prepare or verify any register under the Citizenship Rules, 2003.
    4. Strengthen the Civil Registration System: Raise registration completeness to near universal levels so annual vital statistics reduce dependence on a ten year count.
    5. Constitute an independent data audit: Route quality assurance of the caste and identity fields through the National Statistical Commission before publication.
    6. Release anonymised unit level data: Publish anonymised microdata on a fixed timetable so researchers can test tabulations rather than accept them.
    7. Train enumerators on caste recording: Run a dedicated module for enumerators on recording caste responses and on handling refusals, before the February 2027 round.

    1. Between Census 1951 and Census 2001, the density of the population of India has increased more than three times.

    2. Between Census 1951 and Census 2001, the annual growth rate (exponential) of the population of India has doubled.

  • Ladakh to begin Census 2027 caste enumeration first

    Why in the News

    Ladakh is set to be the first to begin the Population Enumeration phase of Census 2027, from 17 August, with an open-ended caste column. It is the first full caste count in independent India’s Census.

    What is Population Enumeration?

    1. Definition: Population Enumeration is the second phase of the Census, when detailed data on every individual, including caste, is collected.
    2. First phase: It follows Houselisting, which records housing and household amenities.

    Why does caste enumeration matter?

    1. Policy base: Caste data underpins reservation, welfare targeting, and sub-categorisation debates that currently rely on 1931 caste figures.
    2. Open-ended column: An open caste field captures self-reported identity rather than a fixed dropdown, raising classification and comparability challenges.
    3. Security-sensitive geography: Ladakh’s enumeration near the China and Pakistan borders is being geo-tagged, adding a strategic dimension.

    Conclusion

    The caste column makes Census 2027 a landmark data exercise for social policy. The next milestone is the nationwide enumeration schedule.

  • Proof of life: reworking the law on delayed birth and death registration

    Why in the News?

    The Lok Sabha passed the Registration of Births and Deaths (Amendment) Bill, 2026, amending the Registration of Births and Deaths Act, 1969. It requires a Judicial Magistrate’s order for registration of births or deaths delayed by more than two years.

    Key Provisions

    • Judicial Approval: Delayed registration beyond 2 years requires approval from a Judicial Magistrate.
    • Existing Process Retained: Delays up to 2 years continue to require approval from an Executive Magistrate.
    • Objective: Strengthen verification and prevent fraudulent birth or death registrations.

    Why was the Amendment Needed?

    • The 2023 amendment made the birth certificate the primary proof of date and place of birth for: School admissions, Passports, Aadhaar, Voter rolls, Driving licences, and Government jobs
    • Higher importance of birth certificates increased the risk of fraudulent registrations.

    Significance

    • Enhances authenticity of delayed registrations.
    • Supports reliable digital civil registration records.
    • Reduces misuse of birth certificates for identity fraud.

    Challenges

    • Judicial process may increase costs and delays for genuine applicants.
    • Remote and vulnerable populations may face greater difficulty.
    • Adds workload to the lower judiciary.
    • No clear evidence supporting the two-year threshold.

    Back2Basics

    • Registration of Births and Deaths Act, 1969: Makes registration of every birth and death compulsory.
    • Registrar General of India (RGI): Nodal authority under the Ministry of Home Affairs (MHA).
    • Concurrent List: Both Parliament and State Legislatures can legislate on registration.
    • 2023 Amendment: Birth certificate became the primary document for proving date and place of birth.

  • Census 2027 self-enumeration begins in Assam

    Why in the News?

    India has launched its first Digital Census with self enumeration starting in Assam. The online phase continues till 16 August, followed by House Listing from 17 August.

    What is the Census?

    The Census is the official collection of demographic, social and economic data of the population.

    Key Facts

    • Legal Basis: Census Act, 1948
    • Authority: Office of the Registrar General and Census Commissioner, Ministry of Home Affairs
    • Frequency: Every 10 years (Decennial)
    • Nature: Mandatory; information is kept confidential
    • Constitutional Status: Union Subject (Entry 69, Union List)

    What is Self Enumeration?

    Households can submit Census details online instead of depending solely on enumerators.

    Two Phases

    • House Listing: Housing and household details
    • Population Enumeration: Individual demographic details

    Significance

    • Improves data accuracy through digital verification.
    • Enables faster processing and publication.
    • Provides updated data for Delimitation, Welfare targeting, Reservation, Fiscal devolution, and Development planning
    • Replaces reliance on 2011 Census data after the delay of the 2021 Census.

    Prelims Facts

    • First Census: 1872 (non synchronous)
      • A non-synchronous census is a population count that is carried out at different times in different regions rather than all at once on a single date
    • First synchronous Census: 1881
      • A synchronous census is an official population count conducted simultaneously across an entire country within a specific, unified timeframe rather than at different times in different regions.
    • Conducted by Registrar General and Census Commissioner of India
    • Census falls under the Union List.

    [2009] Consider the following statements:

    1. Between Census 1951 and Census 2001, the density of the population of India has increased more than three times.

  • On the method of caste enumeration

    Why in the News?

    The pre-test for the second phase of Census 2027 began on July 6, 2026, in 16 States and Union Territories, using an “open column” for respondents to record their caste. The outcome of this pre-test will decide the final methodology for India’s first statutory caste enumeration since 1931.

    What has changed in this pre-test, and why does its outcome carry more weight than the 2011 exercise?

    1. Pre-test scope: The rehearsal for the second phase of Census ran in 16 States and Union Territories from July 6 to July 20, 2026, and included an open column for respondents to record their caste.
    2. Statutory shift: Unlike the 2011 Socio Economic and Caste Census (SECC), which was conducted outside the purview of the Census Act, caste in 2027 will be enumerated within the second and final phase of the Census itself, giving the count statutory backing.
    3. Methodology still open: Census officials stated that the final caste enumeration methodology will be prepared based on feedback from this pre-test, not fixed in advance.
    4. Historical gap: Caste-wise population, other than Scheduled Castes and Scheduled Tribes, has not been enumerated in independent India since the 1931 Census.
    5. Limited rehearsal access: Self-enumeration was permitted, with the portal accessible only from July 1 to 5, and only in the specific area undergoing the rehearsal.

    Why did the government finally agree to caste enumeration after years of resistance?

    1. Reversal in position: The BJP-led NDA government, after repeatedly opposing caste enumeration, announced on April 30, 2025, that caste would be counted during Population Census 2027.
    2. Opposition pressure: The Congress had consistently demanded a full caste count prior to this announcement.
    3. Coalition pressure: Some NDA allies also pushed for caste enumeration, adding pressure from within the ruling coalition.
    4. State-level precedent: Bihar’s 2022-23 caste-based survey demonstrated a working alternative model and added political momentum for a national exercise.

    Does repeating the open-column method risk reproducing the same unreliable outcome the government itself rejected?

    1. Scale of past failure: The 2011 SECC’s open-column method returned over 46 lakh distinct “caste names,” compared to only 4,147 recorded in the 1931 Census.
    2. Cause of inflation: Respondents recorded surnames or sub-castes as separate categories. For example, “Gupta” and “Agarwal” were recorded separately instead of under the common Baniya caste.
    3. Government’s own admission: In a 2021 Supreme Court affidavit, the Union government stated that the caste count “cannot be exponentially high” through genuine sub-caste bifurcation alone, and that SECC data cannot be relied on for reservation in education, employment, or local body elections.
    4. Method repeated despite the admission: The 2026 pre-test uses the identical open-ended caste column. Officials describe the method as “not final.”
    5. Structured alternative already exists: Current government data lists about 2,650 OBCs on the Central List, 1,170 Scheduled Castes, and 890 Scheduled Tribes — a far smaller, curated framework similar to the list-based model Bihar used, but not yet adopted for the national pre-test.

    What concerns have been raised about the process, and how has the government responded?

    1. Demand for consultation: Opposition parties have sought wider stakeholder consultation before the caste Census is finalised.
    2. Parliamentary question: On December 2, 2025, a Member of Parliament asked in the Lok Sabha whether the government would publish the draft Census questions for public and representative input, and whether it would consider best practices from state-level caste surveys.
    3. Government’s stated process: Minister of State for Home responded that draft questionnaires are field pre-tested before finalisation, consistent with over 150 years of Census practice that incorporates past learnings and stakeholder input.
    4. Repeated deferral through 2025: The government stated multiple times through 2025 that the final caste questionnaire had not been settled.
    5. Notification timeline unresolved: Parliament was informed in February 2026 that caste-related questions would be notified only before the commencement of the second Census phase, leaving the methodology undecided even as the pre-test proceeds.

    5. Why has the Census itself not just the caste count been delayed for over a decade?

    1. Two-phase structure: The Population Census is conducted in two phases, Houselisting and Housing Operations (HLO), and Population Enumeration, spanning over 11 months.
    2. Overdue cycle: The last Census was completed in 2011; the next was constitutionally due in 2021.
    3. Pandemic disruption: The first phase, due to begin April 1, 2020, was delayed by the COVID-19 pandemic that surfaced in India around March 2020.
    4. Unexplained continued delay: Pandemic-related restrictions had ended by 2022, but the government did not specify reasons for the delay beyond that point.
    5. Announced timeline: On June 4, 2025, the government announced that the Population Census, combined with caste enumeration, would be conducted in two phases by February 28, 2027, with the reference date and time of the headcount fixed at 12 a.m., March 1, 2027.

    Conclusion

    The 2027 Census will give caste enumeration statutory backing for the first time, closing the ambiguity that surrounded the unreleased 2011 SECC. The ongoing pre-test’s use of the same open-ended, self-declared caste column risks reproducing the unreliable, exponentially inflated caste count the government itself flagged before the Supreme Court in 2021. Whether the final methodology adopts a curated caste list, as Bihar’s survey did, or persists with the open column, will determine whether the resulting data is usable for its stated purpose of informing reservation, education, and employment policy. The government’s promise to notify questions only before the second phase begins leaves this central design choice unresolved even as the exercise proceeds.

    PYQ Relevance

    [UPSC 2020] Has caste lost its relevance in understanding the multicultural Indian Society? Elaborate your answer with illustrations.

    Linkage: The PYQ directly evaluates the contemporary relevance of caste. The decision to include caste in the 2027 Census itself reflects the continued administrative, political and socio-economic significance of caste in policymaking and governance.
