Muscat: The United Nations estimates that the global human population will reach eight billion by mid-November, and will continue to grow, albeit at a slower pace and with regional disparities, in the decades to come.
A major takeaway from the UN analysis is that the two most populous countries, China and India, will trade places on the podium as early as 2023, according to the UN.
China's 1.4 billion population will eventually begin to decline, falling to 1.3 billion by 2050, the UN projects.
By the end of the century, the Chinese population could fall to only 800 million.
India's population, currently just below that of China, is expected to surpass its northern neighbor in 2023, and grow to 1.7 billion by 2050 -- though its fertility rate has already fallen below replacement level.
The United States will remain the third most populous country in 2050, the UN projects, but it will be tied with Nigeria at 375 million.
