Household sizes are shrinking across the U.S., impacting housing demand. From 2014 to 2024, the average household size dropped from 2.65 to 2.50 nationally, with the largest decline in Lake Havasu City-Kingman, AZ.
That’s a meaningful change in just a decade. It may sound small, but when household sizes shrink, it changes the math of housing demand, since the same number of people may need more homes as households are less crowded.
However, a few metros are moving in the opposite direction, and these markets are worth highlighting because they are so rare.
When household size rises, it often suggests something different is happening locally: more families with children, more multigenerational households, or economic conditions that encourage people to live together rather than separately. The key point is that these “increase metros” are the exception. Most of the country is trending toward smaller households, while only a small set of metros are heading in the opposite direction.
