SpaceX chief executive Elon Musk on Saturday commented on India's declining fertility rate on X, drawing attention to a demographic shift that official data and United Nations reports have been documenting for several years.
"India's birth rate has fallen below replacement. Among those most educated, India's birth rate fell below replacement many years ago," Musk wrote, responding to a post by media outlet AF Post that cited India's Total Fertility Rate (TFR) falling from 2.3 to 1.9 in a decade. The outlet noted that Delhi's TFR now stands at 1.2, lower than Finland's, and cited a June 4 article from The Economist titled "India's population will soon be falling, probably quite fast."
What the Data Shows
India’s national total fertility rate (TFR) of 1.9 has been confirmed by both the 2024 Sample Registration System report and the provisional NFHS-6 data. The replacement fertility rate, the level at which a population remains stable across generations in the absence of migration, is 2.1. Yet, when India’s skewed sex ratio at birth and patterns of female survival are factored in, some demographers argue that the effective replacement rate is closer to 2.2, thereby further increasing the gap.
However, the national figure masks significant internal variation. TFR in urban India fell below replacement as early as 2004, while rural India crossed that threshold more recently in 2023. Southern states such as Kerala and Tamil Nadu have been below a TFR of 1.9 for years, while Bihar, Meghalaya, Uttar Pradesh, Jharkhand, and Manipur remain the only states with fertility rates still above the replacement level and the national average.
Official data shows fertility rates are generally lower among more educated and higher-income groups, although birth rates have declined across all sections of the population over time.
According to the United Nations Population Fund (UNFPA), India's population of 1.46 billion is projected to peak at around 1.7 billion over the next four decades before beginning to decline.
The demographic shift could also influence future political representation, as the freeze on the delimitation of parliamentary constituencies is due for review after 2026. States with slower population growth may face changes in seat allocation if constituency boundaries are redrawn based on current population figures.
Musk has frequently commented on declining birth rates globally. However, the United Nations projects that the world's population will continue to grow in the coming decades despite falling fertility rates in many countries.
