According to the latest Sample Registration System (SRS) 2023 report, the total fertility rate (TFR) in India has fallen to 1.9 per woman. This is a decline from 2.0 in 2021. The report also indicated that for the first time in India’s documented history, the country is below the fertility level that supports population stability.
If you think about this, your grandmother’s generation used to have, on average, more than 6 children. Your mother’s generation probably had 3-4 kids. The average number of children per Indian woman today is less than 2. This figure on a government report is not just another number – it is a major change that will alter India’s way of life in ways most people haven’t realised yet.
Population growth in the world will naturally be halted if fertility rates fall below 2.1 children per woman. India is already beyond this mark. After a long period, during which the country was concerned about the problems that might have been caused by overpopulation, it is now facing the opposite issue, with a small number of young people to take care of an increasingly ageing population.
Almost nowhere else in the world has this change been so quick. India lowered the number of children per family from 6 to less than 2 in 70 years. Even with the implementation of the one-child policy in China, the transformation was not so rapid.
The Numbers Behind the Fertility Shift
The 2023 figures highlight the extent of this demographic change. India’s total fertility rate has decreased from 6.18 in 1950 to 1.9 in 2023. With that, the Crude Birth Rate has decreased from 19.1 in 2022 to 18.4 in 2023, and the Infant Mortality Rate has dropped to 25 per 1,000 live births, down from 26 in 2022.
However, the change is not the same everywhere in India. Bihar, for instance, still has the highest fertility rate, which is 2.8 children per woman, and on the other hand, Delhi has gone down to only 1.2. In other words, the average number of children per family in Bihar is still nearly three, while in Delhi, it is barely one.
The sex ratio at birth is still a matter of concern, standing at 917 girls per 1,000 boys, which suggests that strategies for fewer births are available, but in many regions, the preference for male children still exists.
Why Fertility Rates Dropped So Rapidly
Several forces combined to create this rapid transformation. Education, particularly for women, stands as the biggest driver. When women stay in school longer and enter the workforce, they marry later and have fewer children. This pattern has played out across India as literacy rates climbed.
Economic changes matter too. In agricultural families, children were extra hands for farming and insurance for old age. In urban, service-based economies, children become expensive investments requiring education, healthcare, and housing in cramped city spaces.
Government family planning programs, despite their controversial history, normalised smaller families. The “Hum Do, Hamare Do” campaign made two-child families socially acceptable and even aspirational.
Healthcare improvements created an unexpected effect: as fewer babies died, parents didn’t need to have many children to ensure some survived. Better access to contraception also gave families more control over timing and family size.
Urbanisation changed everything about family life. City living makes large families impractical and expensive. Urban areas also expose families to different social norms where smaller families are seen as modern and responsible.
The Demographic Dividend Window
The reduction in fertility rates introduced a temporary economic opportunity known as the demographic dividend. Currently, India has a larger number of people in the working age (15-59 years) than children and elderly dependents. The proportion of children (0-14 years) dropped from 41.2% in 1971 to 24.8% in 2021.
That implies more people are working and supporting the economy, while fewer people are being supported. The cases of South Korea and Taiwan are good examples of the proper use of demographic dividend periods to gain fast economic growth. India has the same chance, but only if it can generate enough vacancies for the working-age population.
Anyway, this window will not be open forever. It is anticipated that in 2050, 20 per cent of the total Indian population will be senior citizens aged 60 and above. The labour force benefit that India has now will become a dependency problem in the future.
Regional Challenges and Opportunities
The future populations of the different states are going to be totally different. Bihar still has to struggle with the side effects of rapid population growth, although the fertility rate there is 2.8. Schools, hospitals, and job markets are feeling the pressure caused by that growth. These states need continuous investment in education and family planning.
On the other hand, the fertility rates in states such as Delhi are 1.2 and are heading toward ageing societies with a possible lack of workers. In these areas, policies are needed to protect the elderly, and there may even be a necessity to encourage an increase in the birth rates or relocate people there for work.
The southern states of Kerala and Tamil Nadu were the first to go through the fertility transition in India, mainly thanks to education and the healthcare sector. The two states are now the first to show what the future is in the case of an ageing India: healthy populations with a high level of education, but a low number of people in the workforce and growing healthcare needs.
What This Means for India’s Future
The economic ripple effects are enormous. India could benefit from a higher ratio of working-age people, with smaller families enabling better education, healthcare, and a more skilled workforce.
However, the problems are as great as the advantages. Health care institutions that were originally intended for young populations must be restructured to cater to such diseases as diabetes, cancer, and other conditions of ageing, which the elderly face. Social security systems built around joint families must evolve as families shrink.
The education sector faces a paradox: fewer children mean opportunities for smaller class sizes and better quality education, but also potential overcapacity in regions where birth rates have fallen fastest.
The labour markets will be under the influence of the changes in the decade to come. Industries relying on young workers may face shortages, while demand for healthcare, eldercare, and geriatric specialists will surge.
India’s fertility decline is both a success and a challenge, easing population pressure while offering families more choice and boosting potential GDP.
The speed of this transition means India must prepare for an ageing population and regional disparities, shifting from a young to an older nation within a generation.
The next ten years of decision-making will decide if this shift from the past is India’s biggest opportunity or challenge. The saga of India’s demographics is no longer characterised by overpopulation; rather, it is about how to best utilise the available resources.
