18% of Americans Live in a Multigenerational Home

Over the past 50 years, the share of the U.S. population that lives in a multigenerational household has more than doubled, rising from 7 percent in 1971 to 18 percent in 2021, according to a Pew Research Center analysis of the Census Bureau's Current Population Survey. Pew defines a multigenerational household as one that includes at least two generations of adults (mainly aged 25 or older) or a "skipped generation"—grandparents living with grandchildren under age 25. 

Young adults (aged 25 to 29) are most likely to live in a multigenerational household, at 31 percent. In the age group, men (37 percent) are more likely than women (26 percent) to do so.  

Percent of population living in a multigenerational household, 2021

Aged 25 to 29: 31%

Aged 30 to 34: 19%

Aged 35 to 39: 15%

Aged 40 to 64: 19%

Aged 65-plus: 18%

By race and Hispanic origin, non-Hispanic whites are least likely to live in a multigenerational household (13 percent). Asians (24 percent), Blacks (26 percent), and Hispanics (26 percent) are about equally likely to have a multigenerational living arrangement. 

The number-one reason for living in a multigenerational household is financial issues, cited by 67 percent as a reason and by 40 percent as a major reason. Nearly half (45 percent) say they live in a multigenerational household to care (or receive care) for an adult family member. Twenty-four percent are doing so to receive help with child care.

Interestingly, multigenerational living gets positive reviews. Overall, 56 percent say the experience is somewhat/very positive, 26 percent say it is neutral, and 17 percent think it is somewhat/very negative. What explains these positive reviews? The 58 percent majority of those who live in a multigenerational household say it is convenient most/all of the time. Fifty-four percent say it is rewarding most/all of the time. Only 23 percent say it is stressful most/all of the time. And, if you think most of these multigenerational households are crowded, think again. Fully 72 percent of those who live in a multigenerational household say there is plenty of space.
