Where do 8 billion people live?

India is set to overtake China to become the most populous country in the world by the middle of 2023, data released by the United Nations shows.

India’s population is expected to reach 1.4286 billion – 2.9 million more than its neighbour on 1.4257 billion.

The Asian nations have accounted for more than a third of the global population for over 70 years.

China’s birth rate has plunged recently with its population shrinking last year for the first time since 1961.
