Over the past two decades, economists have watched inflation grow faster than ever. Inflation has reshaped not only consumer pricing and budgets, but also the entire makeup of young-adult living. And, its impact on young adults, especially Gen Z and recent college graduates, reaches far deeper than monthly CPI data suggests. Inflation has made living alone and forming new households less economically feasible, bringing about changes in living arrangements that ultimately affect relationships and family formation. The younger generations’ stagnant entry-level wages limit them from the asset ownerships that may protect them from rising prices. Thus, studies show that many young people today choose to return home or live with roommates, as they gain stability towards financial independence.
Housing difficulties have become the clearest and most unmanageable effect of inflation, with price pressures spilling into rents, home ownership, and essential living costs. For one, the rent index for homes increased 3.6% per year from 2015 to 2020, but, now, is rising at least 6.1% annually over the last five years (Zillow); Zillow (2025) also reported that 233 cities had average starter homes valued at $1 million or more, an increase of 148 cities compared to five years ago; And according to Zillow’s “New Homeowner Affordability” data (2025), the amount of income required to deem a new home “affordable” for mortgage payments, insurance, taxes, and maintenance was up to $95,761, about a 13% per year increase over 5 years ago. Rising prices for rent is due to an increase in home prices: for example, today’s 7% mortgage rates stand in clear contrast to the 2–4% rates locked in by earlier buyers (Otrowski et al., 2025). Also, “food at home” prices have increased 4.6% per year since 2020, compared to less than 1% annually in the five years prior (U.S. Bureau of Labor Statistics, 2025).
Taken together, these trends reveal a broader reality: in recent years, prices across both essential expenditures and everyday “social goods” have accelerated far faster than wages. For housing, in particular, steep price inflation combined with elevated mortgage rates has created severe affordability challenges for younger generations. These immense cost increases compare unfavorably with an average hourly wage gain that has consistently increased by less than 7% each year over the last five years, effectively producing real, inflation-adjusted declines in income (Economic Policy Institute, n.d.). The average annual wage for 20- to 24-year-olds is $41,184, compared to $71,552 for those aged 45 to 54. Because younger adults earn significantly less, these non-discretionary expenses consume a disproportionate share of their budgets (Haan, 2025). With stagnant starting wages and minimal asset ownership to protect them from inflation, younger generations face a higher personal inflation rate and are increasingly forced to adopt new, frequently limited financial approaches.
Against the backdrop of increasing living expenses, a growing share of young adults are returning home and forming multigenerational households. Today, an unprecedented 52% of Americans ages 18 to 29 live with a parent or grandparent, displaying the highest level since the 1940s (Fry, Passel, & Cohn, 2020). Importantly, this alteration is not driven by widespread unemployment: the current 9.4% unemployment rate for 20- to 24-year-olds sits well below the 17.1% peak experienced since 2010 (U.S. Bureau of Labor Statistics, 2025). Instead, the key impediment is affordability: lower starting salaries that have failed to keep pace with inflation, paired with rent increases that dramatically outstrip the fixed 5–7% mortgage rates many parents locked in years ago (Bankrate, n.d.). For many young adults, moving home becomes a practical way to save toward a future down payment, pay off student loans, or simply achieve basic economic security.
Culturally, multigenerational living has also become more acceptable. The pandemic, which normalized living at home as a health and logistical necessity, helped shed the stigma long attached to “boomerang kids”, also known as young adults returning to the family home (Pew Research Center, 2012). With more peers making the same choice, the social barrier has weakened, potentially accelerating the trend further. While some young adults never leave home and others return after college, the underlying cause remains consistent: independent living has become increasingly out of reach. In contrast to older generations who secured homeownership when prices and interest rates were lower, today’s young adults face a far more challenging housing landscape, making multigenerational living not a fallback, but an economically rational response to an unaffordable cost of living.
One alternative to moving back home has been cohabitation with similarly stretched peers, a trend often described as the rise of the “roommate economy.” In recent years, the share of young adults living with two or more non-family members has grown sharply. Roughly eight million adults ages 25 to 34 now live in shared households, while Apartment List reports a steep rise in “doubled-up” living arrangements among 18- to 34-year-olds (Hemez & Vespa, 2025). The expansion of co-living companies in cities like New York, Chicago, and Los Angeles further illustrates rising demand, with many residents citing escalating living costs without corresponding wage growth as the primary driver. Cohabitation offers clear economic advantages: shared utilities, groceries, streaming subscriptions, and furniture all create meaningful economies of scale, and rent burdens as a share of income can fall from around 40% for a single renter to 20–25% in a shared arrangement (U.S. Census Bureau, n.d.). Yet even as living with roommates differs from moving home, both are fundamentally economic responses to an unaffordable cost of living, and both delay full independence. That delay brings considerable downstream effects on relationship-building and household formation. Couples increasingly postpone major milestones until reaching economic security, causing the highest median ages at first marriage ever recorded at about 30 for men and 28 for women (Lippert & Fetterolf, 2025). National household-formation data from 2022 to 2024 likewise show slowing rates despite strong employment, signaling that economic pressure is altering when and how young adults form relationships, marry, and start families (Hemez & Vespa, 2025).
Overall, these trends point to a generation whose path to independence has been fundamentally modified by the accelerating cost of living. While the decisions to remain at home, cohabitate, and delay major life relationship decisions are the result of steep inflation in otherwise unavoidable housing categories, these largely financial choices are producing several social dynamics shifts in the structure of the American household. Patterns in multi-generational living and expanded and extended roommate living are slowing the relationship-building process and, in turn, raising the age at which families are formed in the United States. Whether these lifestyle and household-formation patterns persist depends heavily on self-correction in young adults’ real earnings. If either housing affordability increases through lower prices, rents, and mortgage rates, or entry-level wages rise materially in excess of residential living costs, current trends toward shared living and delayed independence may recede. For the more independently-minded and family-oriented, let us hope that those economic adjustments occur sooner rather than later.
