More than half of the projected increase in global population up to 2050 will be concentrated in just eight countries.
They are the Democratic Republic of the Congo, Egypt, Ethiopia, India, Nigeria, Pakistan, the Philippines and the United Republic of Tanzania.
The share of the global population aged 65 years or above is projected to rise from 10% in 2022 to 16% in 2050.
Over the next few decades, migration will be the sole driver of population growth in high-income countries.
India has attained the Replacement Fertility Rate.
It is the rate at which a population exactly replaces itself from one generation to the next.
In India, Population of 0-14 years and 15-24 years will continue to decline.
Age of 25-64 and 65+ will continue to rise for the coming decades.
Those who are already in the 25-64 age bracket, there is a need for skilling, which is the only way to ensure they are more productive and have better incomes.
