BEIJING — China's population shrank for the first time in decades last year as its birthrate plunged, official figures showed Tuesday, adding to pressure on leaders to keep the economy growing despite an aging workforce and at a time of rising tension with the U.S.

Despite the official numbers, some experts believe China's population has been in decline for a few years — a dramatic turn in a country that once sought to control such growth through a one-child policy.

Many wealthy countries are struggling with how to respond to aging workforces, which can be a drag on economic growth, but some experts said the demographic change will be especially difficult to manage in an developing economy like China's.

"China has become older before it has become rich," said Yi Fuxian, a demographer and expert on Chinese population trends at the University of Wisconsin-Madison.

The National Bureau of Statistics reported Tuesday that the country had 850,000 fewer people at the end of 2022 than the previous year. The tally includes only the population of mainland China, excluding Hong Kong and Macao as well as foreign residents.

Over 1 million fewer babies were born than the previous year amid a slowing economy and widespread pandemic lockdowns, according to official figures. The bureau reported 9.56 million births in 2022; deaths ticked up to 10.41 million.

It wasn't immediately clear if the population figures were affected by the COVID-19 outbreak that was first detected in the central Chinese city of Wuhan before spreading around the world. China has been accused by some specialists of underreporting deaths from the virus by blaming them on underlying conditions, but no estimates of the actual number have been published.

China's population has begun to decline nine to 10 years earlier than Chinese officials predicted and the United Nation projected, said Yi. The country has long been the world's most populous nation, but is expected to soon be overtaken by India, if it has not already.

China has sought to bolster its population since officially ending its one-child policy in 2016. Since then, China has tried to encourage families to have second or even third children, with little success, reflecting attitudes in much of east Asia where birth rates have fallen precipitously. In China, the expense of raising children in cities is often cited as a cause.

Yi said that, based on his own research, China's population has actually been declining since 2018, showing the population crisis is "much more severe" than previously thought. China now has one of the lowest fertility rates in the world, comparable only to Taiwan and South Korea, he said.

That means China's "real demographic crisis is beyond imagination and that all of China's past economic, social, defense and foreign policies were based on faulty demographic data," Yi told The Associated Press.

China's looming economic crisis will be worse than Japan's, where years of low growth have been blamed in part on a shrinking population, Yi said.

The last time China is believed to have experienced a population decline was during the Great Leap Forward, a disastrous drive for collective farming and industrialization launched by then-leader Mao Zedong at the end of the 1950s that produced a massive famine that killed tens of millions of people.

China's statistics bureau said the working-age population between 16 and 59 years old totaled 875.56 million, accounting for 62% of the national population, while those aged 65 and older totaled 209.78 million, accounting for 14.9% of the total.

If handled correctly, a declining population does not necessarily translate to a weaker economy, said Stuart Gietel-Basten, professor of social science at Khalifa University in Abu Dhabi.

"It's a big psychological issue. Probably the biggest," Gietel-Basten said.

According to the data from the statistics bureau, men outnumbered women by 722.06 million to 689.69 million, the bureau reported, a result of the one-child policy and a traditional preference for male offspring to carry on the family name.

The numbers also showed increasing urbanization in a country that traditionally had been largely rural. Over 2022, the permanent urban population increased by 6.46 million to reach 920.71 million, or 65.22%.

The United Nations estimated last year that the world's population reached 8 billion on Nov. 15 and that India will replace China as the world's most populous nation in 2023. India's last census was scheduled for 2022 but was postponed amid the pandemic.

Despite a slowing growth rate, the world's population is expected to reach 8 billion people by Nov. 15, according to the latest United Nation's World Population Prospects 2022 report.

In a report released on World Population Day, the U.N. also said global population growth fell below 1% in 2020 for the first time since 1950.

Also Tuesday, the statistics bureau released data showing China's economic growth fell to its second-lowest level in at least four decades last year under pressure from anti-virus controls and a real estate slump.

The world's No. 2 economy grew by 3% in 2022, less than half of the previous year's 8.1%, the data showed.

That was the second-lowest annual rate since at least the 1970s, after the drop to 2.4% in 2020 at the start of the pandemic, although activity is reviving after the lifting of restrictions that kept millions of people at home and sparked protests.

Associated Press writers Huizhong Wu in Taipei, Taiwan, and Kanis Leung in Hong Kong contributed to this report.
