In Europe, 24 percent of the people are 60 and over, and no country has a birthrate sufficient to maintain current population sizes. Who but immigrants can work and fund Europe’s welfare states for its graying publics?
The United Nations’ World Population Prospects says that only 10 percent of global population is in Europe, which is projected to have fewer people in 2050 than today. Just 16 percent of the world’s population is in Africa, but “more than half of global population growth between now and 2050 is expected to occur” there. It will have the world’s highest growth rate, and 41 percent of its people currently are under 15.
