India has taken the top spot for the long term. UN projections show India’s population growing until the early 2060s, peaking at about 1.7 billion. China’s population is expected to keep falling for the rest of the century.
Africa is where the growth is. Nigeria, Ethiopia and the DR Congo are among the fastest-growing countries in the top 20. Nigeria is expected to overtake the United States as the world’s third most populated country later this century.
Several large countries are already shrinking. Japan, Russia, China and Germany all have fertility rates well below the replacement level of about 2.1 children per woman. Their populations are getting older, and growth, where there is any, comes mainly from immigration.
The world as a whole is slowing down. The UN expects the global population to peak at about 10.3 billion in the mid-2080s and then decline slightly.
