Nigeria’s Population to Overtake China, U.S by 2100 – Study
SWITZERLAND, JULY 16 – A new research conducted by the University of Washington’s Institute for Health Metrics and Evaluation has predicted that Nigeria’s population is expected to surpass that of China by 2100.
China’s population, currently the largest in the world is expected to peak at 1.4 billion in four years before nearly halving to 732 million by 2100 while India will become the world’s most populous nation.
By 2100, countries with the five largest populations will include; India with 1.09 billion, Nigeria with 791 million, China with 732 million, the U.S. with 336 million and Pakistan with 248 million.
The study published in the Lancet Medical Journal on Wednesday inferred that the general population of the world will drop due to a reduction in fertility rates. However, the population of sub-Saharan Africa, arguably the poorest region in the world, is expected to triple in size to more than three billion people by 2100.
Researcher, Prof. Christopher Murray, averred that the population explosion in sub-Saharan Africa would lead to migration of Africans to many European and Asian countries seeking more immigrants.
This, he said, would, however, lead to a high incidence of racism.
Murray, who is a former Director of the Harvard Centre for Population and Development Studies, said, “We will have many more people of African descent in many more countries as we go through this.
“Global recognition of the challenges around racism is going to be all the more critical if there are large numbers of people of African descent in many countries.”
According to the research, falling fertility rates mean nearly every country could have shrinking populations by the end of the century.
Meanwhile, in more than 20 countries including Japan, Thailand, and Spain, the population is expected to halve by 2100. This also implies that countries would age dramatically, with as many people turning 80 as there are being born.
Falling fertility rate is due to women having greater access to education and greater access to contraceptives.
In 1950, women were having an average of 4.7 children in their lifetime. The study showed that the global fertility rate nearly halved to 2.4 in 2017 and projects that it will fall below 1.7 by 2100.
As a result, the researchers expect the number of people on the planet to peak at 9.7 billion around 2064, before falling to 8.8 billion by the end of the century.
