In 2024, the average size of a single-family home built for sale in the United States amounted to ***** square feet. Although in the past five years American homes have been shrinking, since 1975, they have almost doubled in size. This trend towards larger homes seems illogical given that the average size of families has shrunk over the same period. Why are American homes so large? Homes in the U.S. are among the largest in the world, only surpassed by Australia. There are thought to be several reasons for this, including the concentration of wealth in the country and the deeply engrained driving culture, which means that cheaper land outside city centers is easily accessible. Where are the largest homes located? The size of homes also varies regionally, with the largest homes being located in wealthy, urban areas and in the South. Large homes, or McMansions as they’re often called, are especially popular in Texas. In 2024, Milwaukee and Omaha had the largest average home size.

The average American household consisted of 2.51 people in 2023.

Households in the U.S.

As shown in the statistic, the number of people per household has decreased over the past decades.

The U.S. Census Bureau defines a household as follows: “a household includes all the persons who occupy a housing unit as their usual place of residence. A housing unit is a house, an apartment, a mobile home, a group of rooms, or a single room that is occupied (or if vacant, is intended for occupancy) as separate living quarters. Separate living quarters are those in which the occupants live and eat separately from any other persons in the building and which have direct access from outside the building or through a common hall. The occupants may be a single family, one person living alone, two or more families living together, or any other group of related or unrelated persons who share living arrangements. (People not living in households are classified as living in group quarters.).”

The population of the United States has been growing steadily for decades. Since 1960, the number of households more than doubled from 53 million to over 131 million households in 2023.

In concordance with the rise of single-person households, the percentage of family households with own children living in the household has declined since 1970 from 56 percent to 40.26 percent in 2022.
