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.
The population could then grow to 11 billion by 2100, according to the United Nations Department of Economic and Social Affairs’s “World Population Prospects” report.
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.
Meanwhile the world’s most-populous country China will see its population drop by 2.2 percent, or around 31.4 million, between 2019 and 2050.
All told, 27 countries or territories have experienced a reduction of at least one percent 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.
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.
That’s close to the minimum of 2.1 births needed to ensure the replacement of generations and avoid long-term population decline 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 global average.
Global 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.
Babies born near oil and gas wells are up to 70% more likely to have congenital heart defects, new study shows
Researchers at the University of Colorado studied pregnant women who are among the 17 million Americans living within a mile from an active oil or gas well
Proximity to oil and gas sites makes pregnant mothers up to 70 percent more likely to give birth to a baby with congenital heart defects, according to a new study.
Led by Dr. Lisa McKenzie at the University of Colorado, researchers found that the chemicals released from oil and gas wells can have serious and potentially fatal effects on babies born to mothers who live within a mile of an active well site—as about 17 million Americans do.
Mueller testimony ‘is going to be a devastating day for the president’: former White House lawyer
The eyes of the nation will be on Capitol Hill on Wednesday when former special counsel Robert Mueller publicly testifies before Congress.
Mueller, who was a federal prosecutor, top DOJ official, and director of the FBI before serving as special counsel, is scheduled to testify before the House Judiciary Committee on Wednesday morning and the House Intelligence Committee on Wednesday afternoon.
"As Democrats prepare for the arrival of special counsel Robert Mueller on Capitol Hill next week, their plans for his day of wall-to-wall testimony is becoming clearer: if Donald Trump were anyone but the president, he would be charged with the crimes Mueller uncovered," MSNBC anchor Nicolle Wallace reported on Friday.
WATCH: Trump blurts out a massive lie about Dem congresswomen — after being asked about Melania
President Donald Trump on Friday falsely accused Democratic congresswomen of using the phrase "evil Jews."
Trump ignited a firestorm over the weekend after saying that the congresswomen of color should "go back" to their countries of origin. At a rally on Wednesday, his supporters chanted "send her back" after Trump attacked one of them, Rep. Ilhan Omar (D-MN).
But on Friday, Trump insisted the congresswomen were the real racists.
"You know what is racist to me? When somebody goes out and says the horrible things about our country, the people of our country, that are anti-Semitic, that hate everybody, that speak with scorn and hate -- that to me is really a very dangerous thing," Trump said.
