JOEL KOTKIN: END OF ONE-CHILD POLICY IS UNLIKELY TO SOLVE CHINA’S LOOMING AGING CRISIS:

n 2050, the number of children in China under 15 is expected to be 60 million lower than today, approximately the size of Italy’s population. It will gain nearly 190 million people 65 and over, approximately the population of Pakistan, which is the world’s sixth most populous country.

The same broad pattern will play out in Taiwan, South Korea, Singapore and Japan, but those countries’ much greater per capita wealth gives them a greater ability to cushion the impact than China. Demographer Nicholas Eberstadt envisions a developing of fiscal crisis in China caused by “this coming tsunami of senior citizens,” with a smaller workforce, greater pension obligations and generally slower economic growth.

These factors were clearly part of the calculus that led to suspending the one-child policy. But if China’s rulers think they can change demographic trends on a dime, they are massively mistaken.

The birthrates of many other East Asian countries have plummeted as well, despite campaigns to promote fertility. In South Korea, Taiwan, Japan, Singapore birthrates are near one per woman, roughly half the rate needed to sustain the current population. With the exception of Singapore, which accepts many immigrants, none have a reasonable path away from rapid aging of their populations and shrinking workforces.

So what is causing this plunge? Gavin Jones, a demographer based at the National University of Singapore, identifies primarily rapid urbanization and sky-rocketing house prices. In 1979, China’s population was 80 percent rural; today the proportion is roughly half that.

This transformation makes reversing the one-child policy largely moot, Jones says. Indeed a 2013 easing of restrictions on family size in certain circumstances elicited far fewer takers than expected. Barely 12 percent of eligible families even applied.

Having children and raising them is difficult and expensive. It turns out it’s easier to get people to stop doing that than it is to get them to start up again.
