Among the most educated... : Elon Musk's warning on India's birth rate
Elon Musk commented on India's fertility data and said the birth rate is below replacement level. He said the decline reflects a wider global trend and had appeared earlier among the most educated groups.

Elon Musk has weighed in on India's demographic trends, warning that the country's birth rate has fallen below the replacement level. Reacting to recent fertility data shared on X, Musk said India's declining fertility rate mirrors a trend seen across several countries and noted that birth rates among the country's most educated population had dropped below replacement levels years ago.
"India’s birth rate has fallen below replacement. Among those most educated, India’s birth rate fell below replacement many years ago," read his tweet.
India's fertility rate has fallen below the replacement level, according to the 2024 Sample Registration System (SRS) report, which showed the country's Total Fertility Rate (TFR) declining from 2.1 to 1.9 children per woman.
The replacement level of fertility, set at 2.1 children per woman, is considered the threshold required for a population to replace itself from one generation to the next without migration. The latest data indicates that most Indian states have now slipped below this benchmark.
According to the report, only six states — Bihar, Uttar Pradesh, Madhya Pradesh, Rajasthan, Chhattisgarh and Jharkhand — continue to record fertility rates above the replacement level.
WHAT DOES REPLACEMENT FERTILITY MEAN?
Demographers consider a Total Fertility Rate (TFR) of 2.1 children per woman as the replacement level — the rate required for a population to replace itself from one generation to the next in the absence of migration.
When fertility remains below this threshold for a prolonged period, population growth gradually slows and can eventually turn negative. Experts warn that sustained low fertility can lead to an ageing population, a shrinking workforce and increased pressure on pension, healthcare and social welfare systems.
INDIA'S DEMOGRAPHIC TRANSITION
India's declining fertility trend was also highlighted in the 2025 State of World Population Report released by the United Nations Population Fund, which estimated the country's fertility rate at 1.9 births per woman, below the replacement level of 2.1.
Although India remains the world's most populous country with a population exceeding 1.46 billion, the latest figures suggest it is entering a new phase of demographic transition characterised by smaller families, lower fertility and slower population growth.
BIRTH RATE VS FERTILITY RATE: WHAT'S THE DIFFERENCE?
While the terms are often used interchangeably, birth rate and fertility rate measure different aspects of population change. While birth rate refers to the number of live births per 1,000 people in a population in a given year, total fertility rate is the average number of children a woman is expected to have over her lifetime.
The two indicators are closely related. A sustained decline in fertility rates typically leads to lower birth rates over time, which in turn can slow population growth and contribute to an ageing society.
