Why should countries care about shrinking populations at a time of climate change, increasing risk of nuclear catastrophe and the prospect of artificial intelligence taking over jobs? At a global level, there is no shortage of people. But drastically low birthrates can lead to problems in individual countries.
Tomáš Sobotka, one of the authors of the U.N. report and a deputy director at the Vienna Institute of Demography, does a back-of-the-envelope calculation to illustrate the point: In South Korea, which has the lowest birthrate in the world at 0.72 children per woman, just over a million babies were born in 1970. Last year, 230,000 were. It’s obviously too simple to say that each person born in 2023 will, in their prime working years, have to support four retired people. But in the absence of large-scale immigration, the matter will be “extremely difficult to organize and deal with for Korean society,” said Mr. Sobotka.
Similar concerns arise from Italy to the United States: working-age populations outnumbered by the elderly; towns emptying out; important jobs unfilled; business innovation faltering. Immigration could be a straightforward antidote, but in many of the countries with declining birthrates, accepting large numbers of immigrants has become politically toxic.
Across Europe, East Asia and North America, many governments are, like Japan, introducing measures like paid parental leave, child care subsidies and direct cash transfers. According to the U.N., the number of countries deliberately targeting birthrates rose from 19 in 1986 to 55 by 2015.
Great piece by @motokorich on what governments can do to increase the birthrate, and how Japan's experiment doing this panned out. https://t.co/ZdaeJY3ZuO
