Empty-nest baby boomers own nearly 3 in 10 (28.2%) large U.S. homes. That’s twice as many as millennials with kids, who own just 14.2% of the country’s large homes. Gen Zers with kids own almost none (0.3%) of them. 

An additional 7.5% of the country’s large homes are owned by baby boomers with households of three adults or more; this category likely consists mostly of adult children living with their boomer parents.

This is based on a Redfin analysis of U.S. Census data from 2022 (the most recent year for which data is available) that breaks down the share of three-bedroom-plus homes owned and occupied by each generation, by household type and size. The three household types are as follows: 1 or 2 adults total living in the home; neither are minor children (for boomers, we refer to this category as “empty nesters”), 3 or more adults total living in the home; none are minor children, and households where adults are living with their minor children. Redfin also broke down the share of three-bedroom-plus homes rented by each generation; that information is below. Adult Gen Zers were 19-25 years old in 2022, millennials were 26-41, Gen Xers were 42-57, and baby boomers were 58-76. See the end of this report for more details on methodology.

It’s worth noting that even though millennials with kids own half as many large homes as empty nesters, there are more millennials than baby boomers. Millennials make up roughly 28% of the country’s adult population, the largest share of any generation. They’re followed by baby boomers (27%), Gen Xers (25%) and Gen Zers (12%). 

Baby boomers own an outsized share of large homes for several reasons, current and historical:

“There’s unlikely to be a flood of large homes hitting the market anytime soon,” said Redfin Senior Economist Sheharyar Bokhari. “Logically, empty nesters are the most likely group to sell big homes and downsize: They no longer have children living at home and don’t need as much space. The problem for younger families who wish their parents’ generation would list their big homes: Boomers don’t have much motivation to sell, financially or otherwise. They typically have low housing costs, and the bulk of boomers are only in their 60s, still young enough that they can take care of themselves and their home without help. Still, some boomers are ready to downsize into a condo or move somewhere new for retirement, and the mortgage-rate lock-in effect is starting to ease–so even though there won’t be a flood of inventory, there will be a trickle.”

Many young families are renting large homes in the meantime. Millennials with kids take up one-quarter (24.8%) of the three-bedroom-plus rentals in the U.S., the largest share of any generational category, followed by millennials without kids (11.6%). Empty-nest baby boomers take up the next-highest-share (11.4%) of three-bedroom-plus rentals.

Young first-time buyers who want a relatively large home should consider new construction, Bokhari said. Almost all newly built homes have three bedrooms or more, and there are a fair amount of them on the market as builders try to get rid of surplus homes they started building at the height of the pandemic buying boom. Some builders are even offering incentives like mortgage-rate buydowns or free upgrades to get new homes off their books. 

We discussed the share of large homes owned by each generation and household type above. In this section, we’ll discuss the share of each generation and household type that owns large homes. 

Empty-nest baby boomers are almost twice as likely as millennial families to own three-bedroom-plus homes. Nearly half (45.5%) ) of one-to-two-person boomer households own large homes. Just over one-quarter (27%) of households consisting of millennials with kids own large homes, and roughly 3% of Gen Zers with kids own them. 

Some young families rent large homes: Roughly 1 in 10 (9.3%)  millennial-with-kid households live in three-bedroom-plus rentals. Others rent smaller units. 

Other millennials live with family or roommates. Of all U.S. millennials (whether they have kids or not), roughly 17% of them live with a family member in a home that family member owns or rents–most likely their parents. Another 10% live in a home owned or rented by someone they’re not related to–most likely a roommate. Seven in 10 are the head of their own household, whether they’re owning or renting. 

Who owns large homes has changed over the last decade. In 2012, empty nesters of the silent generation (who were 67-84 at the time) took up 16% of three-bedroom-plus homes. That’s a smaller share than Gen Xers (who were 32-47 at the time) with kids, who took up 19% of those large homes. 

But one thing has remained the same over time: Baby boomers with no kids living at home take up the lion’s share of big houses. In 2012, empty-nest boomers (who were then 48-66) owned and occupied 26.4% of three-bedroom-plus homes in the U.S., comparable to today’s share. 

Empty-nest baby boomers take up the biggest share of large homes in relatively affordable Rust Belt and southern metros. Baby boomers with one or two people in the household take up roughly one-third of three-bedroom-plus homes in Pittsburgh, PA (32.1%), Birmingham, AL (31.1%) and Cleveland, OH (30.8%), the highest shares in the nation. Next come Buffalo, NY (30.5%) and Virginia Beach, VA (30.4%). Demographics are one reason why Pittsburgh tops this list; the metro skews older: Baby boomers make up 40% of Pittsburgh’s households, a far higher share than Gen Xers (27%) or millennials (20%). 

Empty nesters own at least 20% of large homes everywhere in the country. They take up the smallest share of three-bedroom-plus homes in popular migration destinations and California metros: Riverside, CA (21.9%), Salt Lake City, UT (22%), Austin, TX (22.2%), Houston (23.2%)and San Jose, CA (23.7%). 

Young families take up the smallest share of large homes in coastal California and Florida, where large homes tend to be more expensive, and the largest share in relatively affordable inland metros–but nowhere do millennials with kids take up more than 18% of them. 

Just about one of every 10 three-bedroom-plus homes are owned and occupied by millennials with kids in Los Angeles (9.4%), San Jose, CA (10.4%), San Francisco (10.9%), Miami (11.2%) and New York (11.8%). ) Millennials with kids have the largest share in Indianapolis, IN (17.6%), Minneapolis (17.4%), Cincinnati, OH (17%), Kansas City, MO (16.5%) and Riverside, CA (16.5%). 

This report is based  on a Redfin analysis of U.S. Census American Community Survey micro data from 2022 (the most recent year for which this data is available) that breaks down the share of three-bedroom-plus homes owned and occupied by each generation, by household type. The three household types are as follows: 1 or 2 adults total living in the home; neither are minor children (for boomers, we refer to this category as “empty nesters”), 3 or more adults total living in the home; none are minor children, and households where adults are living with their minor children. Redfin also broke down the share of three-bedroom-plus homes rented by each generation, by household type. 

Gen Zers were 19-25 years old in 2022 (only adult Gen Zers were included), millennials were 26-41 Gen Xers were 42-57, and baby boomers were 58-76.
