These countries tried everything from cash to patriotic calls to duty to reverse drastically declining birth rates. It didn’t work.
…
If history is any guide, none of this will work: No matter what governments do to convince them to procreate, people around the world are having fewer and fewer kids.
In the US, the birth rate has been falling since the Great Recession, dropping almost 23 percent between 2007 and 2022. Today, the average American woman has about 1.6 children, down from three in 1950, and significantly below the “replacement rate” of 2.1 children needed to sustain a stable population. In Italy, 12 people now die for every seven babies born. In South Korea, the birth rate is down to 0.81 children per woman. In China, after decades of a strictly enforced one-child policy, the population is shrinking for the first time since the 1960s. In Taiwan, the birth rate stands at 0.87.
That may be a problem… but our global carbon footprint is a much bigger problem, and part of what can help reduce that is reducing the size of the population.
A cursory search suggests that global population is expected to peak sometime around 2090, so an actual reduction in population really can’t be a primary component of our mitigation strategy relative to a general shift towards green energy. By the time we reach that point, we’ve either solved it or solidly doomed ourselves, population be damned.
