‡ United States Census Bureau definitions:

Household — A household includes all of the people who occupy a housing unit. People not living in households are classified as living in group quarters. (Ex: college residence halls, skilled-nursing facilities, military barracks, …)
Family — A family includes a householder and one or more people living in the same household who are related to the householder by birth, marriage, or adoption.
Non-family Household — A householder living alone or with nonrelatives only.

Note: Family households and husband-wife-couple families do not include same-sex married couples even if the marriage was performed in a state issuing marriage certificates for same-sex couples. Same-sex-couple households are included in the family households category if there is at least one additional person related to the householder by birth or adoption. Same-sex-couple households with no relatives of the householder present are tabulated in nonfamily households.
