The rise in never-married adults is caused by several factors, including later ages for marriage and more people living together and raising children outside of wedlock, the report by the Pew Research Center said.
In 2012, 23 percent of men and 17 percent of women 25 and older had never been married, marking a widening gap between the sexes. In 1960, 10 percent of men and 8 percent of women had never married, said the Pew report.
“Shifting public attitudes, hard economic times and changing demographic patterns may all be contributing to the rising share of never-married adults,” Pew said. The analysis was based on Census Bureau data and a Pew survey.
