Peak population

Sooner or later every country reaches its largest population and then starts to shrink. According to United Nations projections (medium scenario) some have already got there, others will in the coming decades, others will still be growing in 2100.

The world population will peak in 2084, at 10.29 billion people; in 2100 it will be 10.18 billion.
