New Delhi: The Total Fertility Rate (TFR) is a demographic indicator that estimates the average number of children a woman can have during her childbearing years. It is a critical thread that weaves together the story of a nation’s population growth.

This article lets us understand everything about fertility rate, formula and more.

Total Fertility Rate: The concept

The Total Fertility Rate (TFR) builds on the idea of fertility rate. It shows the average number of children a woman would have if she followed the birth rates for different ages in a specific year. TFR gives a clearer view of fertility trends by taking into account women’s ages and their ability to have children.

Understanding the Total Fertility Rate (TFR) Formula

The Total Fertility Rate (TFR) is calculated by adding fertility rates for different age groups. This means you take the age-specific fertility rates and sum them together to get the TFR.

Total Fertility Rate = Σ (Age-Specific Fertility Rate * Proportion of Women in Each Age Group)

This calculation shows the average number of children a woman is expected to have in her lifetime.

It is important to know the difference between birth rates and fertility rates. Birth rates refer to the number of live births per 1,000 women in the total population. The TFR is the most important factor in population growth.

What is the Fertility Rate?

The fertility rate measures how many children a woman is expected to have in her lifetime. It is an important way to understand how populations grow and gives us insights into future population changes. The formula for calculating the fertility rate is:

Fertility Rate = (Number of Births / Number of Women) * 1,000

This equation shows the fertility rate for every 1,000 women who can have children.

Why in the news?

RSS chief Mohan Bhagwat raised concerns on Sunday about declining population growth. He said India’s total fertility rate should be at least 3, above the current one of 2.1.

Bhagwat said, “A declining population is a serious concern. Demographic studies suggest that when a society’s total fertility rate falls below 2.1, it risks facing extinction. This decline does not necessarily require external threats; a society can gradually fade away on its own.”

Decline in India’s Total Fertility Rate (TFR)

According to the National Family Health Survey data released in 2021, India’s TFR has declined from 2.2 to 2, while the Contraceptive Prevalence Rate has increased from 54 per cent to 67 per cent.
