Households in the U.S.
As shown in the statistic above, the number of people per household decreases 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 households to about 123 million households in 2014.
Most of these households, about 34 percent, are two-person households. The distribution of U.S. households has changed over the years, though. The percentage of single-person households has been on the rise since 1970 and makes up for the second largest proportion of households in the U.S. in 2013 of about 28 percent.
In concordance to 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 43 percent.
