A variety of factors contribute to the long-run increase in the share of young adults living with their parents.
The first is the postponement of, if not retreat from, marriage.
For men ages 18 to 34, living at home with mom and/or dad has been the dominant living arrangement since 2009.
In 2014, 28% of young men were living with a spouse or partner in their own home, while 35% were living in the home of their parent(s).
A previous Pew Research Center analysis projected that as many as one-in-four of today’s young adults may never marry.
While cohabitation has been on the rise, the overall share of young adults either married or living with an unmarried partner has substantially fallen since 1990.
Similarly with earnings, young men’s wages (after adjusting for inflation) have been on a downward trajectory since 1970 and fell significantly from 2000 to 2010.
As wages have fallen, the share of young men living in the home of their parent(s) has risen.
In 2014, more young women (16%) than young men (13%) were heading up a household without a spouse or partner.The median age of first marriage has risen steadily for decades.In addition, a growing share of young adults may be eschewing marriage altogether.This is mainly because women are more likely than men to be single parents living with their children.For their part, young men (25%) are more likely than young women (19%) to be living in the home of another family member, a non-relative or in some type of group quarters.
