Thirty-something At Home: America’s Young Adults Are Staying Put Like Europeans

The old American formula used to be simple. Excel in school. Land a steady job. Move out of your parents’ house and don’t look back. That script is breaking. More millennials and Gen Z workers are bunking with family well into their thirties, and housing researchers say the pattern isn’t temporary.

Ivy Zelman, cofounder and executive vice president at Zelman, a Walker & Dunlop Company, put it plainly in a roundtable covered by Fortune. “We are going to start looking a lot more like Europe: multigenerational living.” The negative stigma that once clung to adult children at home has faded. Young people, she said, are often “happy or content” with the arrangement. Rates have risen as mortgage costs climbed and affordability stayed stretched. Zelman expects the share of twenty- and thirty-somethings living with parents to hold near current levels through the rest of the decade.

Back in 1980, only about 15 percent of younger adults lived with their parents. Now the figure sits at 22.4 percent for Gen Zers and millennials, according to Zelman’s data. Just 44 percent of people aged 20 to 39 can afford the median local rent. Baby boomers and Gen X still hold the bulk of housing wealth. Older Americans are far more likely to own a second home. Those 70 and up average nearly $1.4 million in net worth. The under-40 crowd sits closer to $100,000.

A stalled launch. Not a jobs story.

Most of these young adults are working. Realtor.com found that a record 25.2 million people under 35 lived with parents in 2025, topping even the pandemic peak. That’s 33 percent of the age group. Among those 30 to 34, the share has nearly doubled since 2000, reaching 12.7 percent, or about three million people. Seven in ten adults aged 25 to 34 who remain at home are employed. Hannah Jones, senior economist at the firm, told The New York Times that employment rates have stayed relatively stable while co-residence climbed. The math of independent living simply isn’t working.

If early-2000s patterns had held, nearly five million fewer young adults would be sharing a roof with parents today. Median listing prices sit 34 percent above pre-pandemic levels. Rents are up too. The United States still faces a structural shortage of about four million housing units, much of it at the entry-level rung where first-time renters and buyers need to start. The typical first-time buyer is now 40. Every year spent in a childhood bedroom is a year of missed equity.

But the change isn’t only economic. Zelman described a lasting change in how people live. Delayed marriage plays a part. Roughly nine in ten of those 25 to 34 at home have never married. College degrees no longer guarantee an exit. About one in three 25- to 29-year-olds living with parents now holds a bachelor’s degree or higher. Men still outnumber women in the older groups, though the gap has narrowed among younger adults.

So the United States is inching toward patterns long familiar across the Atlantic. Eurostat data for 2025 shows young people in the European Union left the parental home at an average age of 26.3 years, a figure that has hovered near 26 for two decades. Southern and eastern countries sit much higher. Croatia averaged 31.5 years. Greece and Slovakia 30.9. Spain and Italy 30.2. Northern Europe looks different. Finland’s average was 21.4. Denmark 21.8. The gap between north and south is nearly a decade, as Euronews reported. In many southern countries, young people leave later but often skip renting altogether, moving straight into ownership with family help. Parental cash gifts, inheritance, or a family-owned unit are common. Gen Z across Europe has received more such support than any prior cohort.

America’s version is arriving without the same dense urban fabric or cultural ease that long made multigenerational households ordinary in parts of Italy, Spain, or Greece. High land prices and local resistance to denser construction keep supply tight. Zelman has noted that a one-percentage-point swing in the 20-to-39 living-at-home rate equals roughly 500,000 households a year. That’s demand that never materializes as new leases or starter-home purchases. It’s also a variable that housing underwriters now watch closely.

Costs keep compounding. Gasoline, food, education, utilities, and medical care have all risen sharply since 2000. Essential payments now consume more than half of income for many. The personal savings rate recently hit its lowest point since 2007. Forty-two percent of Gen Z renters say they have no money left for anything fun. Those who do pay rent are cutting back elsewhere. Even a group dinner costs more at every step.

And yet some young adults are treating the arrangement as practical rather than shameful. After a friend’s death, one 30-year-old told The New York Times that moving home let him heal and focus on work without constant money worry. Others see it as a way to pay down student debt or save for a future they still hope to build. The Federal Reserve’s latest household survey found 49 percent of adults under 30 living with a parent in 2025, up 12 points since 2019.

Parents, of course, are not a limitless resource. Many boomers and Gen Xers are themselves carrying mortgages or planning retirement. Home equity makes up a fifth of boomer wealth. The intergenerational transfer of that wealth will be slower if younger cohorts never form independent households of their own. Delayed household formation also means delayed family formation for some, with effects that will show up in fertility numbers and school enrollments years from now.

The crowded nest is already changing what people search for in housing. Interest in homes that can hold multiple generations has risen. Accessory dwelling units, in-law suites, and larger suburban houses with extra bedrooms are getting more attention. Until entry-level supply expands and prices ease, that demand will keep building. Young adults who might have rented or bought five years ago are now aging into their thirties still at the family address.

This isn’t failure to launch in the old, pejorative sense. It’s a rational response to prices that rose faster than wages, rates that jumped, and a construction pipeline that never caught up after the last crisis. Europe has lived with later independence for years, especially in the south. America is discovering the same arithmetic. The childhood bedroom that was supposed to empty by 25 now often stays occupied until 30 or beyond. The question is no longer whether the trend continues. It’s how the housing market, family finances, and ideas of adulthood adjust around it.
