Pakistan’s population is likely to reach up to 403 million by 2050 according to recent United Nations (UN) report. The world’s population is probably rise up to 9.7 billion in 2050 from 7.7 billion today, according to the United Nations Department of Economic and Social Affairs’ “World Population Prospects” report. The study predict an image of a future in which a handful of countries see their populaces flow as life expectancy increases while the global growth rate slows among decreasing fertility rates. By 2050, more than half of the world’s population growth will be live 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. In the meantime, the world’s most-populous country China will see its population decline by 2.2 per cent, or around 31.4 million, between 2019 and 2050. 27 countries or territories have experienced a decrease 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 outperforming new births in Belarus, Estonia, Germany, Hungary, Italy, Japan, Russia, Serbia and Ukraine, but that population loss will be balance by an inflow of migrants. The overall international fertility rate, which reduced from 3.2 births per-woman in 1990 to 2.5 in 2019, is expected to drop further to 2.2 in 2050. This is close to the minimum of 2.1 births needed to confirm the replacement of generations and shun long-term population reduction in the absence of migration, according to the United Nations.
The report also projects growing life expectancy generally, including in poor countries where it is now seven years less than the worldwide average. International average life expectancy should reach 77.1 years in 2050 against 72.6 years currently, the report says. In 1990, the average life expectancy was 64.2 years.
