Notes:
The following are not all, but are additional examples of SF 1 tabulations:
P27 -- P30 is a series of tabulations about relationship by household type (family, non-family, and group quarters).
Households by age of householder; by presence of own children; by presence of nonrelatives, and Household type by household size.
P31 -- P36 is a series of tabulations about families. the population in families; the average family size; the family type, and the age of the children in a household
P37 -- P38 is a series of tables for the group quarters population, which includes the population in correctional institutions, college dormitories, military quarters, and other group quarters populations.
Family - 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. Beginning with the 1980 Current Population Survey, unrelated subfamilies (referred to in the past as secondary families) are no longer included in the count of families, nor are the members of unrelated subfamilies included in the count of family members. The number of families is equal to the number of family households, however, the count of family members differs from the count of family household members because family household members include any non-relatives living in the household.
Group quarters - As of 1983, group quarters were defined in the current population survey as noninstitutional living arrangements for groups not living in conventional housing units or groups living in housing units containing ten or more unrelated people or nine or more people unrelated to the person in charge. (Prior to 1983, group quarters included housing units containing five or more people unrelated to the person in charge.) Examples of people in group quarters include a person residing in a rooming house, in staff quarters at a hospital, or in a halfway house. Beginning in 1972, inmates of institutions have not been included in the Current Population Survey.
Household - Consists of all the people who occupy a housing unit. There are two major categories of households, "family" and "nonfamily".
Household, family - A family householder is a householder living with one or more people related to him or her by birth, marriage, or adoption. The householder and all people in the household related to him are family members.
Household, nonfamily - A nonfamily household consists of a householder living alone (a one-person household) or where the householder shares the home exclusively with people to whom he/she is not related.
