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.
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.
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 (in the absence of immigration).
