India’s fertility rate falls below replacement level: Why it matters

India’s fertility rate has for the first time fallen below the level needed to stop the population from shrinking, raising concerns about future labour shortages and an ageing society.

For decades, India has seen rapid population growth. According to government statistics, including the Sample Registration System (SRS) Statistical Report — the country’s largest demographic survey — India has had a falling fertility rate for some years, but the reproduction rate remained high enough to keep the population growing.

The latest SRS report, released last month by India’s Office of the Registrar General and Census Commissioner, said that India’s Total Fertility Rate (TFR) had dropped to 1.9 children per woman – lower than the benchmark level of 2.1 needed to keep the population stable in the long run. TFR is the average number of children that a woman is expected to have in her lifetime. In the 2000s, India’s TFR was around 3.3 births per woman.

So, what is behind reduced fertility? Why does it matter and what are the consequences?

For decades starting in the 1970s, Indian governments and policymakers have tried to battle what they argued was overpopulation — too many people, and too few resources to manage for what was then a relatively poor nation.

Many top-down government initiatives — including a brief controversial effort to forcibly sterilise people in the 1970s — aimed to control India’s population.

Despite that, by 2019, India’s Prime Minister Narendra Modi was still warning of a “population explosion”.

But by 2022, the first signs that India was about to tip over into uncharted territory: The National Family Health Survey released data suggesting that India’s TFR was falling fast, across communities. Yet a year later, India surpassed China to become the world’s most populous nation — and the trend of a declining fertility rate was swamped by the headlines of a 1.5 billion population.
