A growing number of media sources are beginning to note that the world is no longer in danger of overpopulation. Instead, the trends show the primary danger is the opposite: too few babies.
Check out this story:
In Japan, people buy more diapers for the elderly than babies. China, which long enforced a one-child policy, recently raised its child limit to three; the nation expects its population to peak and then decline in 2030. And the population growth rate in the U.S. is at historic lows, reminiscent of the Great Depression era.
A new study published in npj Urban Sustainability explores the future of underpopulation and how it’s likely to affect sustainability goals. Using demographic data from United Nations reports, the study argues that the underpopulation problem is dynamic and twofold: Populations are simultaneously shrinking and ageing.
“Globally, people above 65 years old are the fastest-growing segments of the population and in 2019, for the first time in human history, they outnumbered children younger than 5 years old,” the researchers wrote. “In 2020, 9% of the global population was above 65 years old, accounting for 728 million people. This population is projected to increase more than twofold, reaching 1.55 billion in 2050 and accounting to 16% of global population, at medium fertility rates.”
Or how about this from the New York Times:
All over the world, countries are confronting population stagnation and a fertility bust, a dizzying reversal unmatched in human history that will make first birthday parties a rarer sight than funerals, and empty homes a common eyesore.
Maternity wards are shutting down in Italy. Ghost cities are appearing in northeastern China. Universities in South Korea cannot find enough students, and in Germany, hundreds of thousands of properties are being razed, with the land turned into parks.
Like an avalanche, the demographic forces — pushing toward more deaths than births — seems to be expanding and accelerating. Although some countries continue to see their populations grow, especially in Africa, fertility rates are falling nearly everywhere else. Demographers now predict that by the latter half of the century or possibly earlier, the global population will enter a sustained decline for the first time.
