The total fertility rate (TFR) is the average number of children born to a woman during her reproductive years. In India, the TFR has declined significantly over the past few decades, from 5.0 in 1950-55 to 2.2 in 2015-20, according to data from the National Family Health Survey (NFHS). This decline in TFR is a result of various factors such as increased access to education and employment opportunities for women, improved access to family planning services, and changing social norms and attitudes towards family size.
The decline in TFR has significant implications for India's population dynamics in 2050. With a lower TFR, India's population growth rate is expected to slow down significantly. According to projections by the United Nations, India's population is expected to reach 1.7 billion by 2050, but the annual population growth rate is projected to decline from 1.3% in 2020 to 0.3% by 2050. This slower population growth rate will have several benefits for India, including reduced pressure on resources such as water, food, and housing, and lower healthcare and education costs per capita.
However, a lower TFR also presents some challenges for India. With a smaller workforce relative to the elderly population, there could be a greater burden on the working-age population to support the elderly through pensions and healthcare services. The government will need to ensure that there are enough jobs and economic opportunities for the working-age population to support this demographic shift.
Moreover, a lower TFR could also lead to a shrinking workforce relative to the dependency ratio (the ratio of dependents - children and elderly - to working-age individuals). This could put pressure on the working-age population to support a larger number of dependents, potentially leading to lower economic growth rates and higher taxes for working individuals.
In conclusion, the decline in TFR presents both opportunities and challenges for India's population dynamics in 2050. While slower population growth rates will have several benefits for India, such as reduced pressure on resources and lower healthcare and education costs per capita, there could also be challenges such as a greater burden on the working-age population to support the elderly and a shrinking workforce relative to the dependency ratio. The government will need to implement policies that cater to these demographic shifts and ensure that there are enough jobs and economic opportunities for all individuals in society.
