India is undergoing an asynchronous demographic transition—shifting from high fertility and mortality rates toward sub-replacement fertility and population ageing, with regional states navigating these phases at markedly divergent speeds.

Demographic Transition in Contemporary India

• Demographic Transition Model (DTM): India has firmly progressed into Stage 3 (Late Expanding) and is rapidly moving toward Stage 4 (Low Stationary) as national Total Fertility Rate (TFR) settles at 2.0.
• Current Population Age Structure:
  • Youth Cohort (0–14 years): 23.3% — steadily contracting due to declining fertility.
  • Working-Age Cohort (15–59 years): 66.5% — placing India in its decisive demographic dividend window.
  • Elderly Cohort (60+ years): 10.2% — marking the structural onset of population ageing.
• Spatial Urban Transition: Driven by rural-urban migration and industrialization, India’s urban population share has expanded steadily from 27.8% in 2001 to approximately 35%, intensifying pressure on urban service delivery.

Critical Challenges of India’s Demographic Transition

• 1. Regional Asynchrony (North-South Divergence): Southern and western states have attained sub-replacement fertility, while northern states remain youthful.
  • Empirical Contrast: Bihar’s TFR of 2.8 contrasts sharply with Kerala’s TFR of 1.5, producing conflicting policy demands between school-level skilling and geriatric social security.
• 2. The Demographic Dividend is Not Automatic: A bulging working-age cohort yields growth only if matched by formal, high-productivity employment.
  • Policy Context: The Economic Survey 2024–25 notes the imperative to generate roughly 78.5 lakh non-farm jobs annually to absorb the entering workforce.
• 3. Rapid Ageing and Healthcare Burden: Rising longevity with sub-replacement fertility is accelerating the dependency ratio in early-transition states.
  • Projection: UNFPA’s India Ageing Report 2023 projects India’s elderly population (60+) to double to nearly 20% of the population by 2050.
• 4. Feminisation of Ageing: Women outlive men on average but face lower lifetime formal labor participation, persistent wage gaps, and limited asset ownership, making elderly widows acutely vulnerable.
• 5. Strain on Public Health Systems: The epidemiological transition shifts healthcare burdens from maternal-child interventions toward chronic non-communicable diseases (NCDs), cardiovascular disorders, and dementia, areas where public geriatric infrastructure remains sparse.
• 6. Distress Inter-State Labor Migration: Spatial demographic imbalance drives massive workforce migration from younger northern belts toward industrial corridors in Maharashtra, Gujarat, Delhi-NCR, and Tamil Nadu, straining urban housing, transit, and water supplies.
• 7. Skewed Sex Ratios at Birth: Entrenched son preference persists despite broader fertility declines.
  • Data: NFHS-5 documented a Sex Ratio at Birth (SRB) of 893 in Haryana and 891 in Rajasthan, against the national average of 929.
• 8. Political Economy of Delimitation & Devolution: States that proactively met population control targets voice concerns over potential penalties in parliamentary representation and horizontal tax sharing.
  • Institutional Response: The 16th Finance Commission adjusted the demographic-performance criterion weight from 12.5% to 10% to address fiscal federalism concerns.

Way Forward

• 1. Human Capital Maximization: Upgrade technical skilling, apprenticeships, and public education to convert youth potential into productive economic output.
• 2. Female Workforce Integration: Expand state-supported childcare creches, safe public transit, and targeted vocational training to raise women’s labor force participation.
• 3. Dedicated Geriatric Infrastructure: Institutionalize portable non-contributory pensions, expand primary geriatric clinics, and support community-based palliative care.
• 4. Tailored Regional Strategies: Formulate state-differentiated demographic roadmaps—focusing on schooling, healthcare access, and jobs in northern states, alongside eldercare infrastructure in southern states.
• 5. Portable Social Protection: Implement nationwide portability of health, welfare, and public distribution benefits for inter-state migrant families.

India must shift from managing population numbers to proactively managing demographic change—converting its youth window into sustainable growth while building institutions to support an ageing society.
