Multigenerational living: how it works and what is hard

November 9, 2026

Multigenerational living means two or more adult generations sharing one home, such as grown children living with their parents, or grandparents with their children and grandchildren. Pew Research Center counted 59.7 million Americans living this way in March 2021, 18% of the population. It was far more common in the United States before the postwar suburbs, and extended-family homes are still the most common household type worldwide. It tends to work when money, space and chores are agreed up front, and to go wrong when they are not.

What it is, and how common

Pew's census-based count covers households with "two or more adult generations (mainly ages 25 and older)", or grandparents living with grandchildren under 25. By that count the number of people in such homes has quadrupled since 1971.

In 2010 Pew reported that about a quarter of Americans lived in a multigenerational family household in 1940. By 1980 the share had fallen to 12%, and by 2008 it was back up to 16.1%. Pew names three likely causes of the postwar drop: nuclear-family suburbs, fewer immigrants, and a sharp rise in the health and wealth of people over 65. The suburban nuclear household is the newer arrangement. Why tribes don't get lonely covers the older pattern of a small group who all knew each other.

Worldwide, Pew's 2019 study of living arrangements found that the extended family is the most common household type, with 38% of the world's population in one. Almost half of people in the Asia-Pacific region live this way, against about one in ten North Americans. Pew defines it as a household with relatives beyond children or partners, for example "adults who live with their siblings or parents in addition to their own children."

How it works now

People give different reasons, and Pew's October 2021 survey shows the mix:

• Money. Among adults 25 to 39 living with parents, 57% cite finances as a major reason, against 31% of those 40 and older. Lower-income adults are the most likely to say the arrangement helps them financially: 50% at least a little, against 24% of upper-income adults.
• Care. A third of adults in multigenerational homes say caregiving is a major reason: 25% for adult care and 12% for child care.
• Culture. Pew reports that Asian, Hispanic and Black Americans are each more likely than White Americans to live with extended family, especially immigrants.

Day to day, the households that work tend to settle the same few things. This list is my reading of what the arrangement involves, not a finding from Pew:

1. Who pays what, and how much.
2. Which rooms or hours are private.
3. Who cooks, cleans and drives, and whether that is written down.
4. Who decides when someone needs more care.

What is hard

Pew asked people how it feels. 30% called their experience very positive and 27% somewhat positive. 26% said neither, 14% somewhat negative and 3% very negative. 23% said it is stressful all or most of the time, 40% some of the time, and 36% rarely or never. Among those living with adult relatives other than a spouse or partner, 54% said it is rewarding all or most of the time.

Positive views rose with income: 71% for upper-income adults, 59% for middle and 50% for lower. That fits a plain reading. The arrangement is more often a necessity for people with less money, and people who chose it have an easier time liking it.

Pew does not break down who does the extra work by gender, so I cannot give you a number for how the burden of care and housework splits. If you are planning this, ask the question out loud, because an unspoken split tends to settle on whoever is most willing.

Loss of privacy, old family disputes under one roof, and different habits around money and noise are the other costs people mention. The Pew sources used here give no figures for them.

What you can do this week

You can test the idea before anyone moves.

1. Share one meal a week with the relatives you might live with. Notice who cooks, who clears and who talks.
2. Have the money conversation before the move: rent or share of bills, who owns what, what happens if it ends.
3. Write a one-page agreement covering chores, quiet hours, guests and care. Review it after a month.
4. Plan private space for each adult, even if it is only a door that closes.
5. Agree on an exit. Decide now how much notice anyone gives if it is not working.

If a shared home is too big a step, a weekly table with neighbours is a smaller one. Our piece on how to start a commune covers that route, and what loneliness does to your brain explains why it is worth the effort.
