In April, the United Nations estimated that India had overtaken China as the world’s most populous country. While the announcement received a great deal of media attention, India’s 2024 census will likely reveal that the U.N.’s projections have been vastly overestimated.
According to India’s most recent census data, the country’s population stood at 1.03 billion in 2001 and 1.21 billion in 2011. The U.N.’s 2022 World Population Prospects (WPP) report, however, put these figures at 1.08 billion and 1.26 billion, respectively. Moreover, India’s National Family Health Survey indicated a fertility rate of 1.99 in 2017-19, in contrast to the WPP’s estimate of 2.16.
At the 1974 U.N. population conference in Bucharest, India’s then-Minister for Health and Family Planning, Karan Singh, famously said, “Development is the best contraceptive.” While it is often assumed that income per capita is directly correlated with fertility, declining fertility rates are primarily driven by improvements in health and education, along with the wider availability of contraceptives. This trend is evident in India, where the fertility rate has plummeted in tandem with reductions in infant mortality and rising education levels.
