  • Are India’s small towns being increasingly urbanised?

    Why in the News?

    India still focuses its urban future on megacities, even though only about 500 towns are large cities, while nearly 9,000 are small towns, most with populations below one lakh. Earlier, urbanisation was led mainly by metros, but this pattern is now changing. Small towns are increasingly absorbing surplus labour, migrant workers, and consumption activities as metros face high land prices, stressed infrastructure, and rising living costs. This shift reflects not inclusive growth, but the spread of urban crisis to smaller towns, with serious economic and social consequences.

    How have India’s small towns proliferated since the 1970s?

    1. Metropolitan Concentration: Organised capital accumulation during the 1970s-1990s prioritised large cities as centres of industry, infrastructure, and state investment.
    2. Labour Absorption: Cities like Delhi, Mumbai, Chennai, Kolkata, and later Bengaluru and Hyderabad absorbed surplus labour and expanded consumption.
    3. Spatial Fix: Metros functioned as spatial fixes for capitalism by enabling accumulation through land, infrastructure, and labour concentration.

    Why are India’s metros facing a crisis of over-accumulation today?

    1. Land Detachment: Land prices have become disconnected from productive economic use.
    2. Infrastructure Stress: Urban systems are stretched beyond functional limits.
    3. Cost Escalation: Rising housing and living costs have become unaffordable for working groups.
    4. Accumulation Limits: Metros have exhausted their capacity to absorb surplus capital and labour efficiently.

    Why have small towns emerged as new sites of urbanisation?

    1. Capital Redirection: Small towns offer cheaper land and lower entry barriers for capital.
    2. Labour Availability: They absorb migrants displaced from metros and rural youth exiting agrarian livelihoods.
    3. Functional Integration: Towns such as Sattenapalle (Andhra Pradesh), Dhamtari (Chhattisgarh), Barabanki (Uttar Pradesh), Hassan (Karnataka), Bongaigaon (Assam), and Una (Himachal Pradesh) now act as logistics nodes, agro-processing hubs, warehouse towns, service centres, and consumption markets.

    How are small towns embedded within the urban process?

    1. Urban Continuum: Small towns operate fully within urban capitalist systems rather than existing as rural-urban intermediaries.
    2. Regulatory Gaps: Weaker regulation and minimal political scrutiny facilitate capital expansion.
    3. Cost Arbitrage: Lower land prices and pliable labour make small towns attractive for accumulation under stress conditions.

    Are small towns a better alternative to metropolitan urbanisation?

    1. No Emancipatory Promise: The article rejects the notion that small towns ensure inclusive or equitable growth.
    2. Urbanisation of Poverty: What unfolds is the relocation of rural deprivation into urban spaces.
    3. Informal Labour Dominance: Construction workers without contracts, women in home-based work, and youth in platform economies face insecurity and lack of social protection.
    4. Emerging Hierarchies: Towns such as Bhadol (Madhya Pradesh) and Raichur (Karnataka) show consolidation of power among real estate brokers, contractors, micro-financiers, and local intermediaries controlling land and labour.

    What does this reveal about India’s urban policy framework?

    1. Metro-Centric Bias: Flagship urban missions remain focused on large cities.
    2. Policy Failure: Small towns remain under-governed despite being central to contemporary urbanisation.
    3. Political Neglect: Absence of adequate scrutiny deepens informalisation and inequality.

    Conclusion

    India’s small towns are not emerging as alternatives to the metropolitan crisis but as its extension. They represent a new spatial frontier for capitalist accumulation under stress, marked by informal labour, weak regulation, and entrenched local hierarchies. Without policy recalibration, small-town urbanisation risks reproducing the very inequalities it was expected to resolve.

    PYQ Relevance

    [UPSC 2024] Why do large cities tend to attract more migrants than smaller towns? Discuss in the light of conditions in developing countries.

    Linkage: The question examines structural drivers of rural-urban migration in developing countries. It connects with debates on metro-centric growth, over-accumulation, and the emerging role of small towns as secondary but constrained urban destinations.

  • How Haryana turned around sex ratio at birth, now close to national average

    Introduction

    Sex ratio at birth reflects deep-rooted social preferences, access to technology, and effectiveness of governance. Haryana’s demographic profile was historically distorted due to entrenched son preference and misuse of prenatal diagnostic technologies. The recent improvement indicates a shift driven by administrative vigilance, legal enforcement, and behavioural correction mechanisms, rather than mere awareness campaigns.

    Why in the News

    Haryana’s sex ratio at birth (SRB) rose to 923 females per 1,000 males in 2023, bringing the state close to the national average of 933. This marks a sharp reversal from its historical position among India’s worst-performing states. The improvement follows two decades of sustained interventions, including enforcement against illegal sex selection, medical monitoring, inter-departmental coordination, and district-level surveillance. The state also recorded its best SRB performance in five years, signalling structural rather than episodic change.

    How severe was Haryana’s demographic imbalance earlier?

    1. Historically low SRB: Haryana ranked among the worst Indian states during the 2000s due to female foeticide.
    2. Technology misuse: Easy access to ultrasound and weak regulation facilitated sex-selective abortions.
    3. Structural bias: Son preference reinforced by inheritance practices and patriarchal norms.
    4. National comparison: Haryana consistently performed below the national SRB average for years.

    What institutional measures drove the turnaround?

    1. Legal enforcement: Strict implementation of the (Pre-Conception and Pre-Natal Diagnostic Techniques (PCPNDT) Act, 1994, including registration checks and surprise inspections.
    2. Criminal accountability: Filing of over 1,375 FIRs against illegal practitioners since 2014.
    3. Administrative coordination: Weekly reviews involving health, police, and district administrations.
    4. Tracking mechanisms: Continuous monitoring of ultrasound centres and pregnancy outcomes.

    How did district-level governance contribute?

    1. District surveillance: Identification of high-risk districts and targeted enforcement.
    2. Best-performing districts: Panchkula, Jhajjar, and Rewari crossed 940 SRB.
    3. Worst-performing districts: Palwal, Faridabad, and Panipat remained below the state average, indicating uneven progress.
    4. Outcome-based reviews: Regular district rankings created competitive accountability.

    What role did monitoring of medical practices play?

    1. Ultrasound regulation: Tight scrutiny of ultrasound centres and equipment movement.
    2. Pregnancy audits: Tracking of repeat abortions and abnormal sex ratios at facility levels.
    3. Professional deterrence: Suspension and prosecution of erring doctors.
    4. Sustained vigilance: Monitoring continued even during COVID-19 disruptions.

    Why is this shift considered structurally significant?

    1. Consistency over time: Improvement sustained across multiple years rather than isolated spikes.
    2. Behavioural correction: Reduced acceptance of sex-selective practices at the community level.
    3. Policy credibility: Demonstrates effectiveness of law when combined with administrative resolve.
    4. Replication potential: Offers a governance model for other demographically stressed states.

    Value Addition: Sex Ratio at Birth in India 

    1. National SRB: Approximately 933 females per 1,000 males.
    2. Regional variation: Northern and north-western states historically record lower SRB.
    3. Underlying causes: Son preference, declining fertility, and access to diagnostic technology
    4. Policy instruments: Beti Bachao Beti Padhao, PCPNDT Act, and conditional cash transfer schemes.
    5. Trend: Gradual national improvement, but inter-state disparities persist.

    Conclusion

    Haryana’s improvement in sex ratio at birth underscores that deep-rooted gender bias is not irreversible when governance moves beyond symbolic welfare to sustained enforcement and accountability. The experience demonstrates that demographic correction requires a long-term, law-driven, and institutionally coordinated approach, reinforcing that gender justice must be ensured at the earliest stage of life for social transformation to be durable.

    PYQ Relevance

    [UPSC 2021] “Though women in post-Independent India have excelled in various fields, the social attitude towards women and feminist movement has been patriarchal.” Apart from women education and women empowerment schemes, what interventions can help change this milieu?

    Linkage: Persistent patriarchal attitudes, reflected in practices like female foeticide and skewed sex ratios at birth, show that women’s progress has not translated into social acceptance. Haryana’s SRB turnaround demonstrates that strict legal enforcement, behavioural regulation, and institutional accountability are critical interventions.
