Fertility Transition in India

India has undergone a remarkable fertility transition over the last 25 years, as reflected in successive National Family Health Surveys (NFHS). The country has moved from a high-fertility developing nation to one where most states have reached or fallen below the replacement level fertility of 2.1.

This transition has effectively weakened the “Population Bomb” thesis proposed by Paul Ehrlich and Anne Ehrlich, which predicted that rapid population growth would outpace economic development.

Key Facts Regarding Fertility Transition in India

Historical Context

India’s Total Fertility Rate (TFR) remained very high (around 6 children per woman) during the 1950s–1960s. However, due to family planning measures and socio-economic changes, fertility began to decline steadily from the 1970s.

By 2000, the TFR had reduced to approximately 3.5 children per woman, indicating sustained progress.

NFHS-5 Benchmark

The NFHS-5 (2019–21) reported a TFR of 2.0, marking the first time India fell below the replacement level of 2.1.

Current Estimates

By the mid-2020s, India’s TFR is estimated at around 1.9 births per woman, confirming a continued phase of low fertility.

Regional Variations

Significant regional differences persist.

• Southern states such as Kerala and Tamil Nadu have very low TFR (1.4–1.8).

• Northern states like Bihar and Uttar Pradesh are still closer to replacement levels.

Future Projections

India’s population is expected to peak between 2060 and 2080 (1.7–1.9 billion) before stabilizing or declining.

Key Factors Driving Low Fertility Rate in India

Female Education

Female education is the most significant driver of declining fertility. Educated women tend to delay marriage, pursue careers, and exercise reproductive choices.

Urbanisation

Urban areas have a lower TFR (~1.6) compared to rural areas (~2.1), due to higher living costs, smaller family norms, and career priorities.

Economic Pressures

Rising costs of living, job insecurity, housing challenges, and lack of affordable childcare discourage larger families.

Contraceptive Access

India’s family planning programs have led to a high contraceptive prevalence rate (~67%), enabling effective birth control.

Decline in Son Preference

Traditional son preference is weakening due to education, gender awareness, and economic participation of women.

Changing Social Norms

There is a shift toward “quality over quantity”, where families prefer fewer children and invest more in their education and well-being.

Implications of Low Fertility Rate in India

Positive Implications

• Demographic Dividend: A higher proportion of working-age population boosts economic growth.

• Reduced Resource Pressure: Lower population growth reduces strain on natural resources and infrastructure.

• Improved Social Services: Better delivery of education, healthcare, and public services.

• Better Health Outcomes: Improved maternal and child health due to fewer pregnancies.

Concerns and Risks

• Ageing Population: Elderly population may reach ~20% by 2050, increasing dependency.

• Shrinking Workforce: Fewer young workers may slow economic growth.

• Loss of Demographic Dividend: Without proper policies, the advantage may fade.

• “Getting Old Before Getting Rich”: Risk of ageing before achieving high income levels.

• Sandwich Generation Burden: Working population may face pressure of supporting both children and elderly parents.

Emerging Opportunity

• Silver Economy: Growing demand for healthcare, elderly care services, and retirement-related industries.

Measures for Sustainable Population Growth

Human Capital Investment

Focus on education, skill development (AI, green energy), and healthcare to enhance productivity. Policies like National Education Policy (NEP) 2020 play a key role.

Pro-Family Policies

Reduce the cost of raising children through:

• Affordable childcare (e.g., Anganwadi reforms)

• Paid parental leave

• Tax incentives

Preparing for the Ageing Population

Develop universal pension systems, geriatric healthcare, and age-friendly infrastructure.

Managing Internal Migration

Encourage migration from high-fertility states to low-fertility regions to balance labour demand and supply.

Conclusion

India’s transition to sub-replacement fertility marks a significant demographic milestone, offering opportunities for economic growth and sustainable development. However, challenges such as ageing population, workforce decline, and regional disparities require proactive and well-planned policy interventions.
