Recent data released in the “China Statistical Yearbook 2026” reveals significant changes in the household structure of China. As of 2025, households comprised of one or two individuals accounted for a total of 59.6%, nearing sixty percent. Over the past 25 years, the average number of people per household has decreased by one, indicating a shift away from the traditional multi-generational living arrangements that were once the norm. Industry experts warn that smaller households are contributing to increasing pressures regarding eldercare and child-rearing responsibilities.
According to a report by a financial magazine, data from the National Bureau of Statistics of China indicates that in 2025, there were approximately 515 million households in the country, housing about 1.297 billion people. The average household size was recorded at 2.52 individuals. Under detailed scrutiny, it was found that single-person households represented 26.4% while two-person households accounted for 33.2%. The two categories combined totaled 59.6%, approaching sixty percent. Additionally, when considering households with three or fewer members, they totaled nearly 80%, as noted in correspondences with the “2025 National 1% Population Sample Survey Main Data Report.”
Looking back further, data from the fifth national census in 2000 revealed an average household size of 3.44 individuals. This figure declined to 3.10 in the sixth census conducted in 2010, and further decreased to 2.62 in the seventh census of 2020. The average has continued to drop to 2.52 in 2025, illustrating a continuous contraction in household sizes over the last quarter-century. The once common family structure of three or more members is now fading from the mainstream.
The marriage data from the “China Statistical Yearbook 2026” further highlights evolving trends in family structures. In 2025, around 3.937 million divorce cases were legally processed, correlating to a divorce rate of 2.8%, marking the highest in the last five years. The report underscores the changing dynamics of marriage, with couples marrying later and experiencing higher rates of divorce, both factors contributing to the rise in smaller households.
One of the primary reasons for the increase in smaller households is the declining birth rate. The yearbook reports a birth rate of only 5.63‰ for 2025, which is the lowest recorded in the series. As fewer children are born, it follows naturally that families are becoming smaller. Official figures show there were 7.92 million births in China throughout 2025, while the death toll reached 11.31 million, leading to a net population decrease of 3.39 million. This marks the first time that annual births have fallen below 8 million, a staggering reduction of over 55% compared to the 17.86 million births that occurred in 2016 after the implementation of the two-child policy.
Another contributing factor is the improvement in living conditions, which allows elderly family members and children to no longer reside under one roof as was typical in larger, multi-generational households. Instead, these extended families have been separated into two or three smaller households.
In addition, the mobility of the population plays a significant role in household fragmentation. The seventh national census indicated that by 2020, there were approximately 376 million people who had migrated, with around 125 million moving across provincial borders. Most of this moving population consists of young individuals who often establish single or two-person households in their new locations. Consequently, with each instance of migration, family units are frequently divided.
Professor Jiang Quanbao from the School of Labor Economics at Capital University of Economics and Business predicts that over the next decade, the average household size will continue to decline. He notes that the fertility rates are expected to keep falling, leading to an increase in childless households, while the number of single-person homes expands. Furthermore, the effects of population mobility are contributing to this ongoing trend of household fragmentation.
Jiang emphasizes that as household sizes decrease, the functions and support systems traditionally associated with larger families are also diminishing. This reduction results in weakened intergenerational support for eldercare and child-rearing, thereby challenging the capacity of traditional families to mitigate risks. “With every slight decrease in household size, the demand for social support in eldercare and childcare rises correspondingly,” he states.
Moreover, the reduction in the average number of individuals per household means that caregiving responsibilities that were once distributed among multiple generations are becoming increasingly concentrated and burdensome for fewer individuals.
In addition, Professor Yuan Xin from the School of Economics at Nankai University emphasizes that the declining household sizes are disrupting the equilibrium of supply and demand in traditional eldercare systems. The basic pension replacement rate in China has remained around 45% for an extended period, which is substantially lower than the internationally preferred standard. With the cohort born during the second baby boom between 1962 and 1975 transitioning to retirement, the number of retirees is growing rapidly, putting sustained pressure on the basic pension insurance funds.
Yuan suggests that the impending demographic shifts resulting from population aging will generate a demand for larger financial pension assets. However, he points out that many current eldercare organizations possess characteristics of light assets, extended timeframes, and slow returns, which are not aligned with traditional financial lending preferences.
