AI summaryThis paper examines whether fertility rates stabilize at low levels, challenging assumptions in many population projections that fertility will rebound or reach equilibrium once it falls low. Using UN period data (1950-2023), Human Fertility Database cohort data (1935-1975 across 31 countries), and subnational data from Japan, India, and the US, the authors find no robust evidence of a systematic rebound or stable equilibrium; instead, fertility tends to keep declining once it becomes low. The findings reconcile earlier reports of fertility reversals in some countries during the early 2000s and suggest a need to reexamine equilibrium and rebound assumptions in widely used population projections.
Abstract
Many population projections used by international and government agencies assume that, in today's low-fertility societies, future fertility rates will stop declining and roughly stabilize. This paper assesses the evidence for an equilibrium point or rebound from low levels. We show that there is no robust evidence for a systematic fertility rebound, or for a stable equilibrium point at any fertility level conventionally assumed. Instead, where and when fertility has fallen low, it has tended to keep falling. This is true across a range of data sources, time periods, and fertility measures: United Nations data on period total fertility rates for all country-years from 1950 to 2023; Human Fertility Database data on completed fertility for cohorts born between 1935 and 1975 in 31 countries; and fertility rates in subnational geographies in Japan, India, and the United States. We reconcile these results with a prior literature that documented fertility reversals among some low-fertility countries in the early 2000s. Our findings provide an empirical basis for re-examining the equilibrium and rebound assumptions embedded in widely used population projections.
AI summaryThis paper examines India's rapid, below-replacement fertility transition, noting it diverges from the international pattern where fertility decline typically accompanies broad gains in education, health, women's agency, and economic transformation. Instead, India's compressed fertility decline was driven largely by state-led family-planning interventions, particularly female sterilisation, rather than parallel human development progress. This weakens the conventional link between fertility decline and socioeconomic transformation, raising questions about India's prospects for realizing a demographic (gender) dividend.
Abstract
India's attainment of below-replacement fertility marks a major demographic milestone, yet it presents a paradox when viewed against international experience. In most countries that successfully harnessed a demographic dividend-particularly in East Asia and parts of Europe-fertility decline emerged alongside broad improvements in education, health, women's agency, labour-market opportunities, and structural economic transformation. In contrast, India's fertility transition was unusually rapid, compressed into a few decades, and was driven to a significant extent by state-led family-planning interventions, especially female sterilisation, rather than by comparable advances in human development. This divergence weakened the conventional linkage between fertility decline and socioeconomic transformation.

11. Fertility Transition and India’s Economic Transformation: A Demographic Perspective
AI summaryThis study examines India's demographic and economic transformation from 1992 to 2025, tracking population growth from 0.902 to 1.46 billion, fertility decline from 3.9 to 2.0 births per woman, labour force expansion from 0.324 to 0.617 billion, and GDP growth from $288.21 billion to $3960 billion. It concludes that declining fertility and a growing working-age population have supported a demographic dividend and economic progress, though realizing long-term benefits requires addressing employment generation, skill development, informal employment, and population ageing through investment in human capital and inclusive policies.
Abstract
India has experienced a significant demographic and economic transformation since the early 1990s, driven by changes in population growth, fertility patterns, labour force expansion, and sustained economic development.This study examines the relationship between demographic transition and economic transformation in India during the period 1992-2025 using trends in population, fertility, labour force, and Gross Domestic Product.During the study period, India's population increased from 0.902 billion to 1.46 billion, while the total fertility rate declined from 3.9 to 2.0 births per woman, indicating a transition towards replacement-level fertility.Simultaneously, the labour force expanded from 0.324 billion to 0.617 billion, supporting higher productive capacity and economic growth.India's GDP also increased substantially from US$288.21 billion in 1992 to US$3960 billion in 2025, reflecting rapid structural transformation and economic progress.The analysis highlights that declining fertility and an expanding working-age population have created favourable conditions for a demographic dividend, while challenges such as employment generation, skill development, informal employment, and population ageing continue to influence long-term development.In conclusion, demographic transition has been a major contributor to India's economic transformation, and its long-term benefits depend on effective investment in human capital, productive employment, and inclusive policies that promote sustainable and balanced economic growth.
4 Individual Choice? On the Rise of Love and the Decline of Fertility in Urban Middle- Class India
AI summaryThis paper examines how human development and fertility transition shape India's demographic dividend, with particular attention to gender dimensions. It frames these factors as a 'silent constraint' influencing whether India can effectively harness its demographic potential.

Antibiotic Pollution and Infant Mortality in India: A Research Note
AI summaryThis research note examines how pharmaceutical pollution from antibiotic production contaminates Indian riverways, contributing to antibiotic resistance and infant mortality. The study finds that living downstream of an antibiotic producer increases infant mortality risk by 16%, with antibiotic production estimated to cause 17,000 infant deaths annually in India. The authors call for better monitoring, stronger regulations, improved production processes, and strategic siting of antibiotic manufacturers to reduce these negative externalities on local populations.
Abstract
Abstract The number of deaths from antibiotic resistance is steadily rising and has become a global public health issue. Children in low- and middle-income countries are disproportionately affected, as last-line antibiotics are usually unavailable to them. Pollution of riverways caused by pharmaceutical products is one driver of antibiotic resistance. In this research note, we assess whether this channel contributes significantly to infant mortality in India. We show that living downstream of a producer increases the risk of infant mortality by 16% and that antibiotic production explains 17,000 infant deaths in India per year. These findings suggest that better monitoring, stronger regulations, improved production processes, and strategic considerations on the location of antibiotic producers are needed to ensure that production does not induce negative externalities on the local population.
