The Unexpected Future
20th August 2022
We are entering an unanticipated reality—an era of slow population growth and, increasingly, demographic decline that will shape our future in profound and unpredictable ways. Globally, last year’s total population growth was the smallest in a half-century, and by 2050, some 61 countries are expected to see population declines while the world’s population is due to peak sometime later this century.
This kind of long-term global demographic stagnation has not been seen since the Middle Ages. World population has been growing for centuries, but the last century has dwarfed previous rises. About 75 percent of the world’s population growth has occurred in the last hundred years, more than 50 percent since 1970. But now, population growth rates are dropping, especially in more developed nations, according to the United Nations (all subsequent references to UN research in this essay are drawn from these data).
