Explanation:

This bulge in the working-age population is going to last till 2055, or 37 years from its beginning.Since 2018, India’s working-age population (people between 15 and 64 years of age) has grown larger than the dependant population — children aged 14 or below as well as people above 65 years of age. This bulge in the working-age population is going to last till 2055, or 37 years from its beginning.

Many Asian economies — Japan, China, South Korea — were able to use this ‘demographic dividend’, defined by the United Nations Population Fund (UNFPA) as the growth potential that results from shifts in a population’s age structure. This transition happens largely because of a decrease in the total fertility rate (TFR, which is the number of births per woman) after the increase in life expectancy gets stabilised.
