The world population is expected to climb to 9.7 billion in 2050 from 7.7 billion today, with the population of sub-Saharan Africa doubling, a United Nations report released Monday said.
On the other hand, Pakistan’s population is expected to climb to 403 million by 2050, a United Nations (UN) report said. The study paints a picture of a future in which a handful of countries see their populaces surge as life expectancy lengthens while the global growth rate slows amid declining fertility rates. By 2050, more than half of the world’s population growth will be concentrated in just nine countries: India, Nigeria, Pakistan, the Democratic Republic of Congo, Ethiopia, Tanzania, Indonesia, Egypt and the United States
“The populations of both Pakistan and Nigeria more than doubled in size between 1990 and 2019, with Pakistan moving up in rank from the 8th to the 5th position and Nigeria from the 10th to the 7th position,” said the report. Meanwhile the world’s most-populous country China will see its population drop by 2.2 per cent, or around 31.4 million, between 2019 and 2050.
All told, 27 countries or territories have experienced a reduction of at least one per cent in the size of their populations since 2010 due to low levels of fertility. The report also says deaths are outpacing new births in Belarus, Estonia, Germany, Hungary, Italy, Japan, Russia, Serbia and Ukraine, but that population loss will be offset by an inflow of migrants.
