The homeownership rate for multigenerational households increased by 4.9 percentage points (pp) over the last decade, but there’s another household type that experienced an even larger increase in the homeownership rate over the same period—single parent households.

In further analysis of the Census’s American Community Survey (ACS) data, NAHB dives deeper into the homeownership rate for other family household types: married couples with no children, married couples with children and single parent households. In 2022, most family households were married with no children (44%), followed by married with children (26%), single parents (12%), others (12%), and multigenerational families (6%). This composition has not changed much, with the exception of a gradual decrease in the share of married with children and single parent households, which is offset by an increase in the share of married with no children households.

The homeownership rate for single parent households saw the largest gains in homeownership rate with an increase of 5.7 percentage points over the decade. However, the overall level of homeownership rate for single parent households remains the lowest among all other family household types at just 41%.    Another group that saw a large increase was the married couple with children households, with a 4.5% increase over the decade from 73% to 78%. Like multigenerational households, these increases were spurred on by historically low mortgage rates in 2021.

The only household type to have plateaued was married without children. As a matter of fact, these households saw decreasing homeownership rates for a few years before creeping back up to be at roughly the same rate as they were ten years ago at 84%. Nonetheless, married without children households remain as the group with the highest homeownership rate with an average rate of 84% over the decade.

We also examined the estimated home price-to-income ratio (HPI) for various household types. To calculate the home prices for recent homebuyers we used the median property value for owners who moved into their property within the past year. Here is where we see the effect of how multigenerational households were able to lower their HPI with pooled income and budgets. In contrast are single parent households with their estimated home prices approaching five times their income, indicating that these households are significantly burdened by housing costs.   

Given that homeownership rates jumped in recent years for most household types despite increases in home prices suggests that the low mortgage rates in 2021 made steep home prices more palatable for homebuyers to enter the market. However, it is unlikely that we’ll see a continued increase in homeownership while mortgage rates remain elevated.
