As per a report released on Monday by the United Nations, the world population is likely to reach 9.7 billion in 2050 which is 7.7 billion today. The report also says the population of sub-Saharan Africa will be double.
According to the United Nations Department of Economic and Social Affairs’ “World Population Prospects” report, the population could grow to 11 billion by 2100. The prediction indicates that a handful of countries see their populaces surge as life expectancy lengthens while the global growth rate slows amid declining fertility rates.
India, Pakistan, Ethiopia, Nigeria, the Democratic Republic of Congo, Tanzania, Indonesia, Egypt, and the United States are the nine countries in which more than half of the world’s population growth will be dense by 2050.
Meanwhile, China which is currently the most populous country will see its population drop by 2.2 percent, or around 31.4 million, between 2019 and 2050. As the level of fertility has decreased since 2010, the 27 countries have witnessed a reduction of at least one percent in the size of their populations.
The report also claims that deaths are outpacing new births in Belarus, Estonia, Germany, Hungary, Italy, Japan, Russia, Serbia, and Ukraine but that population loss will be balanced by an inflow of migrants.
The overall global fertility rate, which declined from 3.2 births per-woman in 1990 to 2.5 in 2019, is expected to fall further to 2.2 in 2050.
The United Nation says that to ensure the replacement of generations and to avoid long-term population decline in the absence of migration, minimum 2.1 births needed. In 2050, the global average life expectancy should reach 77.1 years against 72.6 years currently, says report.
