According to official Chinese statistics, most young people born in the 1990s do not want to get married and the divorce rate among married people is nearly 35 percent. More and more families are single-person households.
The data that the China Ministry of Civil Affairs recently released shows that there are currently about 170 million people, born in the 1990s (the post-90s generation) in China, who have a male to female ratio of 54 to 46. This group has reached the age of marriage. The oldest post-90s are in their 30s, and the youngest post-90s are 22 years old. While between 70 and 80 million “post-90s” people were expected to register for marriage, fewer than 10 million “post-90s” couples have actually registered for marriage, which translates into a marriage rate of a little over 10 percent. Further, among the post-90s who are already married, the divorce rate is as high as 35 percent.
Chinese social media comments attribute the low marriage rate among post-90s people to high housing costs and low income. Most of the post-90s are the only child in the family. Once married, a young couple would need to support four elder parents and one young child. The cost can be prohibitive for many of those in the post-90s.
According to data from the Ministry of Civil Affairs, of all age groups, in 2019, marriage registrations in China fell by 8.5 percent year on year, while divorces rose by 5.4 percent in the same period. The data shows that the same trend has continued since 2015.
According to survey data released by the China National Bureau of Statistics in the China Statistical Yearbook, the result has been more families which are single-person households. One-person households have increased consecutively every year, from 13.15 percent in 2015 to 18.45 percent in 2019, .
