The numbers behind a quiet trend
The scale of this shift is larger than most people assume. The share of young adults living with their parents increased in 2024, interrupting the post-pandemic trend of moving out, with roughly a third of adults ages 18 to 34 (32.5%) living with parents according to the latest American Community Survey data, up from 31.8% in 2023, though still below the pre-pandemic peak of 34.5% in 2017. That’s not a spike. It’s a slow drift upward that has held steady for two consecutive years.
Separate Federal Reserve data paints an even sharper picture for the youngest adults. Last year, 49% of adults under age 30 lived with a parent, up 12 percentage points from 2019. Pew Research has found something similarly striking looking at slightly older cohorts. A Pew Research Center analysis found that 52% of adults aged 18 to 29 were living with one or both parents, a level not seen since the era of the Great Depression.
Housing costs sit at the center of it all
Ask economists why this is happening and the answer rarely changes. High living costs, including a national median home price above $400,000 and record rents, are driving young adults home. Renting alone in most major metros now consumes a share of income that would have seemed unreasonable to previous generations trying to launch their own households.
Thrivent’s most recent Boomerang Kids Survey backs this up directly. Top factors driving young adults back home include unaffordable housing, cited by 45%, and job loss or reduced income, cited by 36%. Housing affordability, in other words, isn’t one factor among many. It’s consistently the biggest one, year after year.
The debt and wage math that isn’t adding up
Beyond rent, there’s the slower drag of student debt and wages that haven’t kept pace with living costs. High rent and housing costs, cited by 62% of respondents, and inadequate salary, cited by 38%, are the top reasons young professionals move back home, according to one recent survey of early-career workers. That combination, expensive housing paired with pay that doesn’t stretch far enough, is what turns a temporary stay into something longer.
It’s worth noting that this isn’t only about hardship. Roughly a third of young adults (34%) said their primary reason for living at their parents’ home was saving for a down payment on their own place. For a meaningful share of boomerang kids, home is a launchpad rather than a landing pad, a place to rebuild savings before buying rather than renting forever.
Not just twentysomethings anymore
The image of a fresh college graduate crashing in their childhood bedroom for a summer is outdated. Thrivent’s survey looks specifically at adults aged 18 to 35, and the numbers there are notable. Half of U.S. parents with adult children ages 18 to 35 said this year that a child has moved back home at some point, a figure in line with 2025’s rate of 46%.
The National Association of Realtors has tracked a similar climb in older cohorts too. Forty-one percent of respondents in a recent NAR survey said they had adult children age 18 or older living at home, up from just 18% in 2015. That more than doubling over a single decade suggests this isn’t a pandemic-era blip working its way out of the system. It looks structural.
Where boomerang living is most common
Geography matters enormously here, and the pattern lines up almost exactly with where housing is least affordable. Over 40% of young adults ages 18 to 34 lived in parental homes in New Jersey (44%) and Connecticut (41%), while California and Maryland registered the nation’s third and fourth-highest shares at 39% and 38% respectively. These are expensive coastal markets where rent alone can swallow a paycheck.
Looking at a slightly older age band tells a similar story from a different angle. Adult children are most likely to reside at home in Hawaii (21.6%), New Jersey (20.7%) and Florida (20.1%). Florida stands out slightly, since its cost of living runs lower than the others on that list, which points to caregiving for aging parents as an added motivator in that state rather than affordability alone.
The stigma that used to come with staying home
For decades, moving back in with mom and dad past your mid-twenties carried a quiet embarrassment, a sense of falling behind peers who’d rented apartments or bought starter homes. That social pressure has softened considerably. A majority of respondents, 62%, said the harsh stigma around moving back home has faded compared with previous generations, and 63% say they personally no longer feel embarrassed or judged about their living situation.
Many young adults now frame the choice in explicitly practical terms rather than as a personal failing. Three in four young adults say living with family or in transitional housing is a smart financial strategy rather than a setback, and 26% declared they moved home specifically to save money. That reframing, from failure to strategy, is arguably the biggest cultural change tucked inside this trend.
What it costs parents
None of this support is free, even when no rent changes hands. Many families report cutting back on personal spending, cited by 47%, delaying major purchases or plans at 36%, or postponing personal goals like travel or education at 33%, in order to support their adult children financially. These aren’t small sacrifices tucked into a monthly budget. They’re the kinds of choices that reshape a decade of financial planning.
The hit to long-term savings is where things get more serious. Nearly one in five parents said they would be willing to reduce personal savings or retirement contributions to provide that support. Separately, 38% of parents report that their long-term savings, including retirement contributions, have been impacted by the return of their adult children. Retirement, in many households, is quietly becoming a shared resource rather than a solitary goal.
What actually predicts who leaves and who stays
Beyond broad averages, researchers have identified specific factors that shape an individual’s odds of moving out. Marriage turns out to be the single strongest predictor. Marriage is by far the strongest predictor of leaving the parental home, with married young adults more than four times as likely to live apart from parents as otherwise similar unmarried individuals.
Income and employment matter almost as much. More than a third (34%) of unemployed young adults reside with their parents, compared with 17% among those who have jobs. The pattern continues along the income scale as well, since the share living at home declines steadily with earnings, from nearly 30% among those earning less than $30,000 annually to just 6% among those earning $100,000 or more.
How families are making it work
For all the financial strain this trend can create, plenty of families report that it genuinely strengthens rather than damages relationships. About half (49%) of parents who’ve let their adult children move back in say it improved their relationship, a figure that suggests shared space doesn’t have to mean shared friction. Clear expectations around chores, bills, and timelines seem to make the biggest difference in whether the arrangement feels collaborative or tense.
Financial planners who study these arrangements tend to circle back to the same advice. Setting a rough timeline, agreeing on financial contributions upfront, and treating the stay as a stepping stone rather than an open-ended default all seem to reduce resentment on both sides. It’s a small amount of structure applied to a situation that otherwise tends to drift without it.
Final thoughts
What’s happening across millions of American households right now isn’t a return to some old pattern from the past. It’s a new arrangement built out of genuinely different economic conditions, higher home prices, tighter rental markets, and wages that haven’t kept up, layered onto a culture that’s grown far less judgmental about the whole thing.
Whether this becomes a permanent feature of American family life or eventually eases as housing markets shift is still an open question. For now, the spare bedroom stays made up, the family budget stretches a little further, and a quieter version of adulthood keeps taking shape one household at a time.
