Blame it on the weak U.S. job market or on changing mores, but more young Americans are opting to live with their parents rather than moving out, marrying or living with a partner.

According to a survey by Pew Research Center, this trend is more prevalent among millennials, generally taken as those born from the early 1980s to 2000. This cohort is also known as Generation Y.

Pew found that across all demographics, more and more people are living with their parents.  And for the first time in over 130 years, Americans ages 18-34 are more likely to live with their parents.

Pew said men, African-Americans, Hispanics and less educated young people are more likely to keep living  with mom and dad.

The study found that 32.1 percent of people in the 18-34 age group live in their parents' house. Another 31.6 percent live with a spouse or partner in their own homes. Living alone as single parents or in a home with roommates or renters was the choice of 14 percent.

The rest live with another family member, a non-family member or in group-living situations such as a college dorm.

On the other hand, women, white people, Asian/Pacific Islanders and people with bachelor's degrees are more likely to live with spouses or partners than with their parents.

As for gender, the study said American men, 18-34, live with their parents 35 percent of the time and with a spouse or partner 28 percent of the time. For women, it's 35 percent with a partner and 29 percent with their parents.
