India will overtake China to become the world’s most populated country in just eight years, according to a United Nations report.
Meanwhile, the Chinese population will decrease by 31.4 million, or around 2.2 per cent, between 2019 and 2050.
The report titled ”The World Population Prospects 2019: Highlights” estimated that the world’s population is expected to increase by two million by 2050, from 7.7 billion today to 9.7 billion.
China, with 1.43 billion people in 2019, and India, with 1.37 billion, have long been the two most populous countries of the world, comprising 19% and 18%, respectively, of the global total in 2019.
They are followed by the United States of America.
Moreover, India along with eight other countries will constitute half of the world’s population.
The nine countries expected to show the biggest increase in population are India, Nigeria and Pakistan, followed by the Democratic Republic of the Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States of America.
In all, the population of sub-Saharan Africa is expected to practically double by 2050, the report said.
Between now and 2050, 55 countries are estimated to see their populations shrink by at least 1%
In China, the population is projected to decrease by 31.4 million, or around 2.2 per cent, between 2019 and 2050.
The report has mentioned that the growth in population will happen despite the slowing of the global fertility rate.
In 1990, the average number of births per woman was 3.2.
By 2019 this had fallen to 2.5 births per woman and, by 2050, this is projected to decline further to 2.2 births!
A fertility level of 2.1 births per woman is necessary to avoid national population decline over the long run.
Further, average life expectancy, which increased from 64.2 years in 1990 to 72.6 years in 2019, is expected to increase further to 77.1 years in 2050.
