Reason not fully known, but survey says cohabitation may play a role

More people born between 1980 and 1989 are remaining single compared with the decade before, a survey released on Tuesday found.

Nearly 1 in 5 men and 1 in 8 women in the age group have never married, according to the Fudan Yangtze River Delta Social Transformation Survey. Back in 2005, official figures showed that the ratio of men and women between 30 and 34 who remained unmarried was 12 percent and 7 percent.
