Long Slide Looms for World Population, With Sweeping Ramifications
Fewer babies’ cries. More abandoned homes. Toward the middle of this century, as deaths start to exceed births, changes will come that are hard to fathom.

All over the world, countries are confronting population stagnation and a fertility bust, a dizzying reversal unmatched in recorded history that will make first-birthday parties a rarer sight than funerals, and empty homes a common eyesore.
Maternity wards are already shutting down in Italy. Ghost cities are appearing in northeastern China. Universities in South Korea can’t find enough students, and in Germany, hundreds of thousands of properties have been razed, with the land turned into parks.
Like an avalanche, the demographic forces — pushing toward more deaths than births — seem to be expanding and accelerating. Though 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.
A planet with fewer people could ease pressure on resources, slow the destructive impact of climate change and reduce household burdens for women. But the census announcements this month from
China and
the United States, which showed the slowest rates of population growth in decades for both countries, also point to hard-to-fathom adjustments.
spirals exponentially. With fewer births, fewer girls grow up to have children, and if they have smaller families than their parents did — which is happening in dozens of countries — the drop starts to look like a rock thrown off a cliff.
“It becomes a cyclical mechanism,” said Stuart Gietel Basten, an expert on Asian demographics and a professor of social science and public policy at the Hong Kong University of Science and Technology. “It’s demographic momentum.”
Some countries, like the United States, Australia and Canada, where birthrates hover between 1.5 and 2, have blunted the impact with immigrants. But in Eastern Europe, migration out of the region has compounded depopulation, and in large parts of Asia, the “demographic time bomb” that first became a subject of debate a few decades ago has finally gone off.
South Korea’s fertility rate dropped to a record low of 0.92 in 2019 — less than one child per woman, the lowest rate in the developed world. Every month for the past 59 months, the total number of babies born in the country has dropped to a record depth.

even iPhones.
To goose the birthrate, the government has handed out baby bonuses. It increased child allowances and medical subsidies for fertility treatments and pregnancy. Health officials have
showered newborns with gifts of beef, baby clothes and toys. The government is also building kindergartens and day care centers by the hundreds. In Seoul, every bus and subway car has pink seats reserved for pregnant women.
But this month, Deputy Prime Minister Hong Nam-ki admitted that the government — which has spent more than $178 billion over the past 15 years encouraging women to have more babies — was not making enough progress. In many families, the shift feels cultural and permanent.

municipalities have been consolidated as towns age and shrink. In Sweden,
some cities have shifted resources from schools to elder care. And almost everywhere, older people are being asked to keep working. Germany, which previously raised its retirement age to 67, is now considering a bump to 69.
Going further than many other nations, Germany has also worked through a program of urban contraction: Demolitions have removed around 330,000 units from the housing stock since 2002.
recently increased to 1.54, up from 1.3 in 2006. Leipzig, which once was shrinking, is now growing again after reducing its housing stock and making itself more attractive with its smaller scale.
“Growth is a challenge, as is decline,” said Mr. Swiaczny, who is now a senior research fellow at the Federal Institute for Population Research in Germany.
Demographers warn against seeing population decline as simply a cause for alarm. Many women are having fewer children because that’s what they want. Smaller populations could lead to higher wages, more equal societies, lower carbon emissions and a higher quality of life for the smaller numbers of children who are born.
But, said Professor Gietel Basten, quoting Casanova: “There is no such thing as destiny. We ourselves shape our lives.”
The challenges ahead are still a cul-de-sac — no country with a serious slowdown in population growth has managed to increase its fertility rate much beyond the minor uptick that Germany accomplished. There is little sign of wage growth in shrinking countries, and there is no guarantee that a smaller population means less stress on the environment.

Many demographers argue that the current moment may look to future historians like a period of transition or gestation, when humans either did or did not figure out how to make the world more hospitable — enough for people to build the families that they want.
Surveys in many countries show that young people would like to be having more children, but face too many obstacles.
Anna Parolini tells a common story. She left her small hometown in northern Italy to find better job opportunities. Now 37, she lives with her boyfriend in Milan and has put her desire to have children on hold.
She is afraid her salary of less than 2,000 euros a month would not be enough for a family, and her parents still live where she grew up.
“I don’t have anyone here who could help me,” she said. “Thinking of having a child now would make me gasp.”
