RUDONG, China—At the edge of the East China Sea, where salt flats meet the Yangtze River delta, this coastal city of 1 million is aging faster than any other in China. Forty percent of Rudong’s residents are now over 60, a demographic milestone that arrived a decade earlier than Beijing’s projections—and a direct consequence of the one-child policy that was first tested here in 1980 before becoming national law.
Ten years after China officially ended the policy, allowing couples to have two, then three children, Rudong’s streets tell a story of unintended consequences. Empty playgrounds stand beside shuttered schools, while senior activity centers overflow with retirees playing mahjong under fluorescent lights. The city’s labor force has shrunk by 20% since 2010, according to local government data, forcing factories to recruit workers from inland provinces or automate production lines.
The Policy’s Birthplace Now Faces Its Aftermath
Rudong was chosen as the pilot site for the one-child policy because of its agricultural economy and stable population. Officials at the time believed strict birth controls would accelerate modernization. Instead, the city’s fertility rate collapsed to 0.8 births per woman by 2020—far below the replacement level of 2.1—and has shown no signs of recovery despite national incentives like cash bonuses for second children and extended maternity abandon.
“We were the model for the country,” said Zhang Wei, a retired local official who helped implement the policy in the 1980s. “Now we are the model for what comes next.” Zhang, now 72, lives alone in a government-subsidized apartment complex where the average resident is 68. His only child, a 45-year-old engineer, moved to Shanghai a decade ago and visits twice a year.
Aging at Warp Speed
China’s national median age is expected to reach 48 by 2050, but Rudong has already surpassed that threshold. The city’s pension system, designed for a younger workforce, is under strain: contributions from current workers cover only 60% of payouts, with the rest drawn from reserves that are projected to run dry by 2035, according to a 2023 report by the Rudong Social Security Bureau.
The economic ripple effects are visible. Local hospitals have repurposed pediatric wards into geriatric care units, while real estate developers pivot to building retirement communities. A 2024 study by the Chinese Academy of Social Sciences found that Rudong’s GDP growth has slowed to 2.1% annually, half the national average, as younger workers migrate to cities with better job prospects.
National Lessons from a Local Crisis
Beijing has taken note. In 2021, the central government designated Rudong as a “demographic transition pilot zone,” funneling funds into elder care infrastructure and tax breaks for businesses that hire older workers. Yet these measures have done little to reverse the trend. A survey by the Rudong Civil Affairs Bureau found that 78% of residents over 50 say they would not have a second child even if offered financial incentives, citing the high cost of living and lack of childcare support.
“The problem isn’t just the policy—it’s the entire social contract,” said Li Jianmin, a demographer at Nankai University who has studied Rudong for two decades. “People here don’t trust the system to support them in old age, so they don’t take the risk of having more children.”
The Next Decade
Rudong’s government has begun experimenting with radical solutions. Last year, it launched a “reverse migration” program, offering cash subsidies and housing to young families willing to relocate from inland provinces. So far, only 1,200 have taken the offer—far below the 10,000 needed to stabilize the workforce. Meanwhile, the city is betting on automation: a new industrial park on the outskirts of town now houses robotics firms producing everything from textile looms to elder-care robots.
Yet for all the planning, Rudong’s future remains uncertain. The city’s last maternity ward, which delivered 3,000 babies in 1990, now averages 300 births a year. Its oldest resident, a 103-year-old woman named Wang Meiying, lives in a nursing home where the staff outnumber the residents under 80. When asked about Rudong’s future, she smiled and said, “I won’t be here to see it.”
In Beijing, policymakers are watching closely. A 2025 report by the National Health Commission, obtained by The Wall Street Journal, warned that Rudong’s demographic collapse could spread to other coastal cities within a decade. The report urged “urgent reforms” to pension systems and elder care, but stopped short of proposing specific measures. For now, the central government has not announced any new policies in response.
