India is set to overtake China as the world’s most populous nation by 2022, BBC News reported, citing a new UN study on global population trends.
Currently, China has a population of 1.38 billion, compared with India’s 1.31 billion.
But by 2022, India’s population will draw even with that of China, at 1.4 billion people, and then exceed it, CNN said, citing the UN study.
The new projection has India overtaking China’s population six years earlier than previously predicted.
According to the forecasts, India will have 1.5 billion people by 2030 and 1.7 billion by 2050. The population of China, meanwhile, is expected to remain stable until the 2030s, and then decline.
The current world population of 7.3 billion will reach 9.7 billion in 2050 and 11.2 billion in 2100, according to the study.
The report also said that Nigeria will replace the United States as the world’s third most populous country by around 2050.
Africa is expected to account for more than half of the world’s population growth over the next 35 years.
It said half of the world’s population growth between 2015 and 2050 is expected to be concentrated in nine countries: India, Nigeria, Pakistan, the Democratic Republic of Congo, Ethiopia, Tanzania, the US, Indonesia and Uganda.
The populations of 28 African countries are projected to more than double, and by 2100, 10 African countries are projected to have increased by at least a factor of five.
“The concentration of population growth in the poorest countries presents its own set of challenges, making it more difficult to eradicate poverty and inequality, to combat hunger and malnutrition,” John Wilmoth, director of the UN’s Population Division, was quoted as saying.
