China’s projected population crash has garnered a lot of attention for the last decade. Enough of it for the country to remove it’s One Child Policy in an attempt to boost falling birth rates.
This nosedive will also change the shape of the Chinese population, with older adults outnumbering younger adults and children. This increases old-age dependency ratios that can put pressure on social systems like healthcare.
On the other hand, several African countries—including the DRC, Ethiopia, and Tanzania—are predicted to rapidly climb the most populous countries ranks after 2050.
Finally, based on current estimates, no country will cross the 1 billion mark again.
