China’s population is already declining. The country has been shrinking since 2022, and the trend is accelerating. With a total fertility rate of roughly 1.0 in 2025, far below the 2.1 needed to maintain a stable population, China is now among the lowest-fertility countries in the world. The current population stands at about 1.416 billion, but that number will fall steadily for decades to come.
How Fast Fertility Has Fallen
The speed of China’s fertility collapse is historically remarkable. In the 1960s, Chinese women had an average of about 7 children each. By 1980, that number had dropped to 2.74. It continued falling and slipped below 1.5 in 2019, then hit 1.03 in 2022. It has stayed at or near 1.0 since then.
To put that in perspective: a fertility rate of 1.0 means each generation of parents is producing roughly half the number of children needed to replace themselves. In less than six decades, China went from one of the highest fertility rates in the world to one of the lowest, joining South Korea and parts of Southern Europe at the bottom of global rankings.
The one-child policy, which ran from 1980 to 2015, played a major role in starting this decline. But the policy’s legacy is now less important than a broader cultural shift. Even after the government loosened restrictions to allow two children in 2016 and three children in 2021, birth rates kept falling. Surveys consistently show that people of childbearing age simply don’t want larger families, regardless of what the government permits.
Why the Three-Child Policy Isn’t Working
China’s government introduced the three-child policy in May 2021, hoping to reverse the trend. It hasn’t. Researchers studying the policy’s impact have concluded it is unlikely to cause a “baby boom” for a straightforward reason: having a third child requires having a second one first, and most couples aren’t even doing that. The proportion of current childbearing-age adults who already have two children is small.
Multiple social surveys conducted after the earlier two-child policy found the same pattern. Willingness to have children remained low, and births didn’t grow as expected. The shift in fertility culture appears to run deeper than policy. Young Chinese adults face high housing costs, intense educational competition for their children, and workplace pressure that makes raising even one child expensive and exhausting. Government permission to have more children doesn’t address any of those barriers.
Fewer Marriages, Fewer Births
The decline in births is closely tied to a decline in marriages. China recorded just 6.1 million marriage registrations in 2024, a drop of 20.5% from the previous year. The marriage rate fell to 4.3 per 1,000 people. In the first quarter of 2025, registrations dropped another 8% compared to the same period in 2024. Since the vast majority of births in China occur within marriage, fewer weddings translate directly into fewer babies.
This isn’t a temporary dip. Young adults are marrying later or choosing not to marry at all. The economic pressures that discourage childbearing also discourage marriage, particularly the cost of housing, which remains a de facto prerequisite for many couples.
An Aging Population at an Unprecedented Scale
As births fall, the share of older adults is rising rapidly. In 2020, about 172 million people in China were 65 or older, roughly 12% of the population. By 2050, that group is projected to more than double to 366 million, making up over 26% of the population. More than one in four Chinese residents will be 65 or older.
This shift will reshape daily life. Demand for healthcare and eldercare will surge while the supply of younger workers to provide those services shrinks. Rural areas, where younger residents have already migrated to cities in large numbers, will age even faster. Urbanization has also contributed to lower fertility by converging rural and urban birth rates, meaning there is no large pool of higher-fertility rural families to offset the decline.
A Shrinking Workforce
The economic consequences center on one core problem: fewer workers supporting more retirees. China’s working-age population in 2050 is projected to be only about 73% of its 2010 level. That is a massive contraction for the world’s second-largest economy, one that built its growth model on abundant, affordable labor.
The picture is slightly less dire than raw population numbers suggest because education levels and productivity per worker have risen. Researchers who account for these factors estimate that “effective labor input” (a measure combining the number of workers with their skills and productivity) grew at about 0.4% per year from 2015 to 2030, even as the raw working-age population shrank by about 0.6% annually. But productivity gains can only partially offset a workforce that is shrinking this quickly.
Pressure on the Pension System
China’s pension system faces a ticking clock. Without reform, the country’s main urban worker pension fund is projected to record its first annual cash-flow shortfall in 2033, meaning it would pay out more in a single year than it takes in. By 2042, the fund’s accumulated reserves would be completely exhausted.
The government is already acting on this. A phased increase in retirement ages would push those deadlines back, delaying the first annual shortfall to 2049 and reserve depletion to 2058. But even with that reform, the system is still expected to accumulate an unfunded deficit of roughly 1,715 trillion yuan by 2100. Delayed retirement buys time; it doesn’t solve the underlying math of too few contributors and too many retirees.
How Far the Population Could Fall
At a fertility rate of 1.0, each generation is roughly half the size of its parents’ generation. If that rate persists, China’s population could fall below 1 billion by the 2060s and continue dropping. Even modest improvements in fertility, say to 1.3 or 1.4, would still mean decades of decline because there are simply fewer women of childbearing age entering their twenties and thirties each year. The shrinking is, in demographic terms, already locked in for at least the next 30 years.
No country has successfully reversed a fertility decline this deep through government policy alone. Financial incentives for childbearing have produced only small, often temporary bumps in countries like Japan and South Korea. China’s situation is compounded by its scale: the social infrastructure, pension obligations, and labor market adjustments required are enormous. The population decline is not a future possibility. It is the present reality, and its effects will deepen for decades.
