India's Fertility Rate Has Fallen Below Replacement Level

A Generation-Long Collapse

India’s fertility rate has undergone a transformation that few demographers would have predicted at the pace it actually occurred. In 1992, the average Indian woman was expected to have 5.7 children over her lifetime. By 2021, that figure had dropped to 2.0 — and the decline has not stopped there.

The most recent data from Our World in Data, drawing on United Nations estimates, shows that India’s fertility rate reached 1.994 births per woman in 2022, and fell further to 1.975 births per woman in 2023. Both figures sit below the replacement threshold of 2.1 — the level at which a population sustains itself without migration.

This is not a rounding error or a statistical blip. It represents a structural shift in how Indian families are forming, and it carries implications that will ripple through the country’s economy, labor markets, and social systems for decades.

What Replacement-Level Fertility Actually Means

The concept of replacement-level fertility — roughly 2.1 births per woman — is the demographic equilibrium point. Above it, a population grows naturally. Below it, absent immigration, a population will eventually shrink as older cohorts are not fully replaced by younger ones.

India crossed that threshold sometime around 2021, and the 2022 and 2023 readings confirm the country is now firmly below it. The 2023 figure of 1.975 is not dramatically below replacement, but the direction of travel matters as much as the current level. Historically, once fertility rates fall below replacement, they rarely recover to it without significant policy intervention — and even then, results are mixed.

For context, many high-income countries have spent decades below replacement level. South Korea’s rate is now below 1.0. Japan has been managing a shrinking working-age population for years. India is entering this territory from a very different starting point — still a young country, still urbanizing — but the trajectory is now unmistakable.

The Drivers Behind the Decline

No single factor explains a fertility decline of this magnitude. The drop from 5.7 in 1992 to under 2.0 in 2023 reflects the convergence of several long-running trends.

Urbanization has played a central role. As more Indians have moved to cities, the economic calculus of having children has shifted. In rural agricultural settings, children historically contributed to household labor and provided old-age security. In urban environments, the costs of raising children — education, housing, healthcare — are higher, and the economic returns to parents are less direct.

Female education and workforce participation have expanded substantially over the same period. Research across dozens of countries consistently shows that as women gain access to education and economic opportunity, fertility rates fall. India’s improvements in female literacy and secondary school enrollment since the 1990s have been significant, even if uneven across states.

Access to family planning has also improved. Government programs promoting contraception and maternal health, combined with greater availability of private healthcare, have given more Indian women the ability to choose the number and timing of their children.

State-level variation remains important context. India is not a monolith. States like Kerala and Tamil Nadu reached below-replacement fertility years ago, while others in the north and east are still above it. The national figure of 1.975 in 2023 is an average that masks this internal diversity — but the direction is consistent across nearly all states.

The Demographic Dividend Is Narrowing

For much of the past three decades, India has benefited from a demographic dividend: a large and growing working-age population relative to dependents. This structural advantage has supported economic growth, kept labor costs competitive, and given India a window of opportunity that China, for instance, is now closing.

With fertility now below replacement, that window is beginning to narrow. The working-age share of India’s population will continue to grow for some years — there is a lag between fertility decline and its effects on age structure — but the trajectory is set. India will eventually face the same aging pressures that have challenged Europe, East Asia, and parts of Latin America.

The timing matters enormously. India has a narrowing opportunity to invest in the productivity and skills of its current young population before the dependency ratio begins to shift. Policymakers, planners, and institutions that rely on demographic assumptions built in the 1990s or 2000s will need to update their models.

What Comes Next

The 2022 reading of 1.994 and the 2023 reading of 1.975 are the most recent data points available, and they suggest the rate is still drifting downward rather than stabilizing. Whether India follows the path of East Asian economies — where fertility has continued falling well below 2.0 — or finds a floor closer to replacement level will depend on factors that are difficult to predict: economic conditions, housing costs, social norms around family size, and policy choices.

What is clear is that India’s demographic story has entered a new chapter. The country that was once synonymous with rapid population growth is now grappling with the same below-replacement arithmetic that defines the demographic challenge of the 21st century.
