Space per person in American homes, 1973 to 2025

By Rohit Gaur · Last updated October 30, 2026 · Report a mistake

Divide the median new American home finished in 2025 by the average US household and you get 857 sq ft of floor area a person — an index built from two national figures, not a measurement of who lives in new homes. In 1973 the figure was 507 sq ft. Space per person grew 69% in 52 years, while the house itself grew only 40% — because the household inside it lost half a person.

The series

The line is one division: the Census Bureau’s median new single-family home that year, over the average number of people in an American household that year. Both series are annual, both run from 1973, and both come from the Census Bureau — new homes from the Survey of Construction, households from the Current Population Survey.

Space per person peaked in 2015 at 971 sq ft, the same year the houses did, and has fallen 12% since. It is still two thirds above 1973, and a sixth above the 1990s, when a new home averaged 738 sq ft a person across the decade — about what the average standing home gives a person today by the same division.

Two changes, not one

Houses grew and households shrank, and the space one person lives in is the two divided. Taking the 52-year move in logarithms — the one split that adds to 100% whichever factor you hold still first — 65% of the gain came from bigger houses and 35% from smaller households.

Holding each half still in turn makes the same point in square feet:

• Today’s home with 1973’s household of 3.01 people: 712 sq ft each, not 857.
• 1973’s home with today’s household of 2.50 people: 610 sq ft each, not 507.

Neither number is a forecast. They are the arithmetic of the two series, and they show that a commentary about “ever bigger American houses” is describing about two thirds of what happened.

The homes people actually live in

New homes are not the housing stock. The federal energy survey measures every occupied home — flats, mobile homes and 1950s bungalows included — and puts the average at 1,845 sq ft (EIA). Across the same 2.50 people, that is 738 sq ft each: a seventh less than a new home gives. The survey’s own figure, which divides each home by the people in it before averaging, is 782 sq ft per household member — higher, because a home with one or two people in it has a lot of floor per person and counts as much in that average as a home with five.

The gap is what “new” buys. A new home is bigger than the average standing home, and it is bought by a household that can afford it; the stock figure includes everyone else.

What this measures, and what it does not

• A median home, a mean household. The Census Bureau publishes the median new home (it also publishes the mean, 2,378 sq ft, which is in new-home-size.csv) and the mean household size. Each is the better figure of its own survey: house sizes have a long right tail, household sizes run from 1 to a handful. Dividing one by the other gives a representative household in a representative new house, not any actual house.
• Two different samples. The homes are new single-family completions — about 1,005,000 of them in 2025. The households are all 134.8 million American households, most of which live in older homes. The line is a comparison of two populations, which is why the section above puts the lived-in stock beside it.
• Floor area means the Census Bureau’s definition: all completely finished floor space, measured to the outside of the exterior walls, with the garage, the carport, the porch and any unfinished basement or attic left out (Census Bureau).
• Household counts are weighted to people, not to housing units. The Bureau says so on the table itself: HH-6 uses the householder’s person weight, so its household count does not match the Housing Vacancy Survey’s count of occupied units. For an average that is the right weighting; for counting dwellings it is not.
• Two years carry a footnote. 2021 is the Bureau’s revised figure, re-weighted to the 2020 census, which is the base every later year uses. The 2025 figure also carries the Vintage 2025 population estimates, so part of the change from 2024 is methodological.
• Nothing here is adjusted for anything. No inflation, no household composition, no region. The average house size page has the size distribution and the regional split.

Work it out for your own home

A number this size is easier to judge against something you can measure. The square footage calculator takes a room at a time, the measuring guide covers what to include, and how big 2,000 square feet is draws the area to scale.
