The average American family in 2023 consisted of 3.15 persons. Families in the United States According to the U.S. Census Bureau, a family is a group of two people or more (one of whom is the householder) related by birth, marriage, or adoption and residing together; all such people (including related subfamily members) are considered as members of one family. As of 2023, the U.S. Census Bureau counted about 84.33 million families in the United States. The average family consisted of 3.15 persons in 2021, down from 3.7 in the 1960s. This is reflected in the decrease of children in family households overall. In 1970, about 56 percent of all family households had children under the age of 18 living in the household. This percentage declined to about 40 percent in 2020. The average size of a family household varies greatly from state to state. The largest average families can be found in Utah, California, and Hawaii, while the smallest families can be found in Wisconsin, Vermont and Maine.

In 2024, 34.59 percent of all households in the United States were two person households. In 1970, this figure was at 28.92 percent. Single households Single mother households are usually the most common households with children under 18 years old found in the United States. As of 2021, the District of Columbia and North Dakota had the highest share of single-person households in the United States. Household size in the United States has decreased over the past century, due to customs and traditions changing. Families are typically more nuclear, whereas in the past, multigenerational households were more common. Furthermore, fertility rates have also decreased, meaning that women do not have as many children as they used to. Average households in Utah Out of all states in the U.S., Utah was reported to have the largest average household size. This predominately Mormon state has about three million inhabitants. The Church of the Latter-Day Saints, or Mormonism, plays a large role in Utah, and can contribute to the high birth rate and household size in Utah. The Church of Latter-Day Saints promotes having many children and tight-knit families. Furthermore, Utah has a relatively young population, due to Mormons typically marrying and starting large families younger than those in other states.

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.

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 made up the second largest proportion of households in the U.S. in 2022, at 28.88 percent.

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.

Households in Italy are larger in the south than in the north of the country. In Campania, the average size of households was of 2.6 people in 2023, with an increase compared to 2022, while in Marche, Apulia, and Sicily households had about 2.4 members. Trentino-South Tyrol and Veneto were the only northern regions ranging in the top-10. However, in recent years, the average number of people per household decreased in Italy. Between 2010 and 2024, the mean size of families ranged from 2.41 to 2.3 components. Structure of Italian families Nationwide, 35 percent of the households consisted of families without a nucleus, such as people living alone, families consisting of two siblings, or a parent living with a child who is separated, widowed or divorced. Furthermore, couples with children made up 31 percent of all households in Italy, representing the second most common household structure. While the average size of families experienced a decrease, one/single person households were on the rise. In 2022, there were 8.36 million single-person households in Italy, almost one million more than in 2012. More babies in the south Analyzing the birth rate in the Italian macro-regions could be useful to better understand the size of the households. In the south and on the islands, the birth rate was higher than in any other area of the country. In 2023, the Southern regions recorded a birth rate of 7 babies per 1,000 inhabitants. Similarly, on the islands, there were 6.7 births per 1,000 residents. However, on a national scale, the births dropped constantly in the last years. In 2023, 6.4 children were born every 1,000 inhabitants, three infants less than in 2002.
