The Federal Reserve Bank of Minneapolis just handed U.S. housing data a numbers-goes-to-bedroom-with-your-parents problem. In 2024, HPOP, the homeowners-to-population ratio, finds that only 22% of adults under age 35 actually own their home. The traditional owner-occupancy headline rate says 37% for under-35 households. That gap is the whole story, and it is bigger than it looks because the old metric counts housing units, not adults.

HPOP corrects the blind spot by counting individuals. In the Minneapolis Fed approach, the “under-35 homeownership” number drops from about a third to 22% once you include everyone living in an owner-occupied house, including grown children, partners, and extended family who live there but do not own. The researchers peg the nationwide share of adults living in owner-occupied homes without actually owning at 13.9%. One detail they called out as especially surprising: 9% of all U.S. adults 18 and older live in an owner-occupied home as the child of the owner. Put plainly, a meaningful chunk of the “youth homeownership” story is actually “youth co-residing inside someone else’s ownership.”

Why should executives care? Because housing is not just a household statistic. It is the primary wealth engine for most Americans, and the wrong measurement can lead to the wrong conclusion about affordability, credit stress, and where wealth is being built versus where it is being blocked. The Minneapolis Fed researchers also point out that the older measure misses entire categories of residents. Their new ratio can capture people such as nursing-home residents and students in dorms, who do not show up in owner-occupancy data at all. That means HPOP is trying to be closer to “ownership outcomes,” not “where an owner lives.”

They illustrate the distortion with a hypothetical cul-de-sac. Using the standard owner-occupancy framing, you might see 80% if four out of five houses have an owner living inside. But when HPOP-style counting includes all adults living across those homes, only half actually own. It is not a semantic tweak. It is a shift in what the statistic is measuring, and it changes what you think is happening to the youngest cohort over time. The paper shows that HPOP for 25-year-olds fell from 20% in 2006 to a low of 12% in 2015, then recovered to just 14% by 2024. The researchers say this is nowhere near pre-financial-crisis levels, even as recent headlines have suggested a young-adult homeownership rebound.

To be clear, the Minneapolis Fed researcher Erik Hembre cautioned against turning this into doom. He said most people eventually become homeowners, and the younger generation is still young enough that the future is not fully written. But the data does suggest that “at some point” is arriving later than in the past, and later than the standard 35-year cutoff implies. He also offered a systems-level argument about why that matters: changes in the economy, an aging society, and medical advancements leading to longer lifespans can effectively extend “youth” for homeownership purposes into the mid-30s. In other words, if your dashboards still treat 35 as the end of the youth window, you may be mis-timing risk and misreading who is truly accumulating housing wealth.

There is also a practical correlation executives will notice: Hembre said affordability tracks the gap between HPOP and owner-occupancy tightly at the state level. High-cost states like Hawaii and California show the largest drops between the two measures. Lower-cost states like North and South Dakota show minimal differences. He attributed this primarily to co-residency rates, meaning how many young adults live with parents or parents live with adult children. Importantly, he warned against overclaiming causation, calling his paper a “first step” and saying more research on the relationship is likely to follow.

Meanwhile, the generational fracture is not new, it is just getting easier to see. The source notes that consultant Jason Dorsey argued in 2015 that millennials were splitting into younger, more financially strained versus older, more established cohorts. Business Insider reported in 2021 that the pandemic deepened an intra-generational divide between “millennial rich” and “millennial poor.” Now the housing-market data lines up with that narrative. The National Association of Realtors’ latest generational trends report says baby boomers remained the largest share of home buyers in 2026, while the overall first-time buyer share fell to a record low of 21%. Within millennials, it found younger millennials aged 27 to 35 saw their share of first-time buyers plunge from 71% to 60% in a single year. Older millennials have become the highest-earning buyer segment, with median household income of $132,700, and they increasingly act as repeat, equity-leveraging buyers instead of first-timers.

That divergence maps to a broader wealth story the source lays out: millennials’ total net worth nearly quadrupled since 2019, rising from $3.94 trillion to $15.95 trillion by late 2024. But about $2.5 trillion of that increase came directly from home-price appreciation among millennials who already owned property, concentrated among those who bought early, disproportionately older millennials. Younger millennials remain locked out of the mechanism driving those gains. The source also points to student debt as part of the pressure: 39% report student loans with a median $30,000 balance, compared with 27% of older millennials.

For boards, lenders, and investors, HPOP is not a feel-good reframe. It is a measurement correction that can ripple through underwriting assumptions, consumer demand models, and how you interpret credit and wealth gaps. If the “under-35 homeownership” baseline is overstated because it is really counting co-residents, then the market may look healthier than it is for the people who most need housing entry. The strategic stakes are simple: if you calibrate products, capital allocation, and risk models off the wrong ownership signal, you may underprice the gap you are trying to serve and overestimate the uptake you are trying to predict.
