In a milestone for humanity, the global population hit 8 billion on Tuesday after having added a billion people in the last 12 years.
India was the largest contributor to the milestone, having added 177 million people, while China, whose contribution to the next billion in the global population is projected to be in the negative, the UN said. India is expected to surpass China as the world's most populous nation by next year.
The UN Population Fund (UNFPA), in a special graphic to mark the global population reaching eight billion, said Asia and Africa has driven much of this growth is expected to drive the next billion by 2037, while Europe's contribution will be negative due to declining population.
The world added a billion people in the last 12 years. UNFPA said that as the world adds the next billion to its tally of inhabitants, China's contribution will be negative.
“India, the largest contributor to the 8 billion (177 million) will surpass China, which was the second largest contributor (73 million) and whose contribution to the next billion will be negative, as the world's most populous nation by 2023,” UNFPA said.
The UN said that it took about 12 years for the world population to grow from 7 to 8 billion, but the next billion is expected to take about 14.5 years (2037), reflecting the slowdown in global growth.
World population is projected to reach a peak of around 10.4 billion people during the 2080s and is expected to remain at that level until 2100.
For the increase from 7 to 8 billion, around 70 per cent of the added population was in low-income and lower-middle-income countries.
