India's Fertility Rate Falls From 3.2 To 1.9; Delhi Records Lowest, But Why Is India's Population Still High?

India, the world's most populous country with more than 1.4 billion people, is entering a new demographic phase. Fresh data released through the Sample Registration System (SRS) shows that the country's Total Fertility Rate (TFR) has dropped to 1.9 in 2024, falling below the replacement level of 2.1 for the first time.

The figure marks a significant change in India's population story. In 2000, India's fertility rate stood at 3.2 children per woman. By 2014, it had fallen to 2.3. Now, just a decade later, it has slipped below the level needed to maintain a stable population in the long term.

Delhi recorded the lowest fertility rate in the country at just 1.2, highlighting how rapidly family sizes are shrinking in urban areas.

What Is The Total Fertility Rate?

The Total Fertility Rate, or TFR, refers to the average number of children a woman is expected to have during her lifetime.

Demographers consider 2.1 to be the "replacement level." This means that, on average, each generation has enough children to replace itself. The extra 0.1 accounts for factors such as child mortality and other demographic realities.

When fertility falls below 2.1 for a sustained period, a country's population eventually begins to shrink unless migration offsets the decline.

With India's TFR now at 1.9, the country has officially crossed below the replacement threshold.

Indian Families Are Having Fewer Children

The new data reflects changing social and economic realities across India.

More women are pursuing education and careers, urbanisation is increasing, healthcare has improved, and the cost of raising children continues to rise. As a result, many couples are choosing to have one or two children instead of larger families.

This trend is visible across much of the country and is no longer limited to metropolitan cities.

If Fertility Is Falling, Why Is India's Population Still Growing?

Many people may wonder why India's population continues to increase despite declining birth rates.

The answer lies in a concept known as "demographic momentum."
India experienced very high birth rates for several decades. As a result, the country today has one of the largest young populations in the world. Millions of young adults are currently entering their childbearing years.

Even though each family is having fewer children, the sheer number of young couples means that births still outnumber deaths.

Experts often compare this to a fast-moving train. Even after the brakes are applied, the train continues moving forward for some distance before coming to a stop. Similarly, population growth continues for decades even after fertility rates decline.

Delhi Records The Lowest Fertility Rate

Among all states and union territories, Delhi reported the lowest fertility rate at 1.2.
This means the average woman in Delhi is having little more than one child during her lifetime.

Such low fertility levels are already common in several developed countries and often lead to ageing populations, labour shortages, and slower population growth over time.

When Will India's Population Start Declining?

Although fertility has already fallen below replacement level, India's population is not expected to decline immediately.

According to United Nations population projections, India's population will continue growing for several more decades because of demographic momentum.

Experts estimate that India's population could reach around 1.7 billion before peaking sometime during the 2060s. After that, the country's population is expected to gradually begin declining.

What Challenges Could India Face?

A slowing population growth rate brings both opportunities and challenges.
In the short term, a large working-age population can boost economic growth if enough jobs are created. However, in the long run, lower birth rates can lead to an ageing society.

Countries with very low fertility rates often face challenges such as:

• Fewer workers entering the labour force
• Higher healthcare and pension costs
• Increased pressure on younger generations to support older citizens
• Slower economic growth

India still has time to prepare for these changes, but experts say long-term planning will be crucial.

A New Chapter In India's Population Story

For decades, discussions about India focused on rapid population growth. The latest fertility data suggests that the conversation is beginning to change.

While India's population will continue growing for some time, the decline in fertility signals a major demographic shift. The country's future challenges may no longer revolve around population growth alone, but also around managing an ageing population, creating jobs for young people, and maintaining economic growth in a changing demographic landscape.

India's fertility rate falling below replacement level is not just a statistic-it marks the beginning of a new chapter in the country's development journey.
