Elon Musk has pointed to a fall in India’s birth rate, saying it has dropped below the level needed to maintain population size.
“India’s birth rate has fallen below replacement. Among those most educated, India’s birth rate fell below replacement many years ago,” Musk wrote in a post on X.
He was reacting to data shared online that showed a steady decline in fertility levels across the country.

What do the latest numbers show?
Recent data indicates that India’s total fertility rate (TFR) has declined to 1.9 births per woman. This is down from about 2.3 a decade ago and marks the first time it has gone below the replacement level of 2.1.
The figures also show that only a few states, including Bihar and Uttar Pradesh, remain above this level. Most other states have already fallen below it.
Delhi recorded a fertility rate of 1.2, which is lower than that of Finland.

What is the replacement level?
The replacement level is the number of children a woman needs to have, on average, for a population to stay stable from one generation to the next. This level is usually set at 2.1.
When fertility falls below this mark for a long period, population growth slows. Over time, this can lead to a decline in population size and a rise in the share of older people.
Are there differences across regions?
The decline in fertility is not the same across the country.
Northern states such as Bihar still have higher fertility rates, while southern and urban areas have seen faster declines. Cities like Delhi and states such as Tamil Nadu have recorded some of the lowest levels.

This shows a gap between more developed and less developed regions in terms of population trends.
What do global reports say?
The United Nations Population Fund (UNFPA) has also reported that India’s fertility rate is now below replacement level. It noted that while the rate has fallen, the country still has a population of more than 1.4 billion.
The agency said issues such as early marriage, gender gaps and access to healthcare continue to affect population trends in different parts of the country.
Is India’s population still growing?
India’s population is still increasing, even though fewer children are being born on average.

Experts say this is due to population momentum, where a large number of young people continue to have children. However, if fertility remains low, growth is expected to slow in the coming years and may eventually reverse.
The latest data shows a shift in India’s demographic pattern, with long-term effects likely on the workforce, economy and social structure.
