A household includes all of the people who occupy a housing unit. A housing unit is a house, an apartment, a mobile home, a group of rooms, or a single room occupied (or if vacant, intended for occupancy) as separate living quarters. Separate living quarters are those in which the occupants live separately from any other people in the building and that have direct access from the outside of 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 people who share living quarters.
In 100-percent tabulations, the count of households or householders always equals the count of occupied housing units. In sample tabulations, the numbers may differ as a result of the weighting process.
A measure obtained by dividing the number of people in households by the number of households (or householders). In cases where household members are tabulated by race or Hispanic origin, household members are classified by the race or Hispanic origin of the householder rather than the race or Hispanic origin of each individual.
Relationship to Householder
The phrase "Coverage Improvement Adjustment" was included in the table outlines and the technical documentation before the review, analysis, and recommendation on whether to adjust Census 2000 data for coverage improvement was completed. As the data are not adjusted, a zero (0) will appear. This phrase does not refer to any other outreach or collection opertions that were introduced to improve coverage in Census 2000.
The data on relationship to householder were derived from the question "How is this person related to Person 1," which was asked of Persons 2 and higher in housing units. One person in each household is designated as the householder (Person 1). In most cases, this is the person, or one of the people, in whose name the home is owned, being bought, or rented. If there is no such person in the household, any household member 15 years old or over could be designated as the householder (that is, Person 1).
Households are classified by type according to the sex of the householder and the presence of relatives. Two types of householders are distinguished: family householders and nonfamily householders. 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 of the people in the household related to him or her are family members. A nonfamily householder is a householder living alone or with nonrelatives only.
Includes a person married to and living with a householder. This category includes people in formal marriages, as well as people in common-law marriages. The number of spouses is equal to the number of "married-couple families" or "married-couple households" in 100-percent tabulations. Marital status categories cannot be inferred from the 100- percent tabulations since the marital status item was not included on the 100-percent form.
Includes a son or daughter by birth, a stepchild, or an adopted child of the householder, regardless of the childs age or marital status. The category excludes sons-in-law, daughters-inlaw, and foster children.
A son or daughter of the householder by birth, regardless of the age of the child.
A son or daughter of the householder by legal adoption, regardless of the age of the child. If the stepson/stepdaughter of the householder has been legally adopted by the householder, the child is then classified as an adopted child.
A son or daughter of the householder through marriage but not by birth, regardless of the age of the child. If the stepson/stepdaughter of the householder has been legally adopted by the householder, the child is then classified as an adopted child.
A child under 18 years old who is a son or daughter by birth, marriage (a stepchild), or adoption. In certain tabulations, own children are further classified as living with two parents or with one parent only. For 100-percent tabulations, own children consist of all sons/daughters of householders who are under 18 years of age. For sample data, own children consist of sons/daughters of householders who are under 18 years of age and who have never been married, therefore, numbers of own children of householders may be different in these two tabulations.
"Related children" in a family include own children and all other people under 18 years of age in the household, who are related to the householder, except the spouse of the householder. Foster children are not included since they are not related to the householder.
Includes any household member related to the householder by birth, marriage, or adoption, but not included specifically in another relationship category. In certain detailed tabulations, the following categories may be shown:
The grandson or granddaughter of the householder.
The brother or sister of the householder, including stepbrothers, stepsisters, and brothers and sisters by adoption. Brothers-in-law and sisters-in-law are included in the "Other relative" category on the questionnaire.
The father or mother of the householder, including a stepparent or adoptive parent. Fathers-in-law and mothers-in-law are included in the "Parent-in-law" category on the questionnaire.
Includes the mother-in-law or father-in-law of the householder.
By definition, these are spouses of the children of the householder.
Anyone not listed in a reported category above who is related to the householder by birth, marriage, or adoption (brother-in-law, grandparent, nephew, aunt, cousin, and so forth).
Includes any household member who is not related to the householder by birth, marriage, or adoption, including foster children. The following categories may be presented in more detailed tabulations:
Includes roomers or boarders, who live in a room in the household of Person 1 (householder). Some sort of cash or noncash payment (e.g., chores) is usually made for their living accommodations.
A person who is not related to the householder and who shares living quarters primarily to share expenses.
A person who is not related to the householder, who shares living quarters, and who has a close personal relationship with the householder.
Foster children are people under 18 placed by the local government in a household to receive parental care. They may be living in the household for just a brief period or for several years. Foster children are nonrelatives of the householder. If the foster child is also related to the householder, the child should be classified as that specific relative.
A person who is not related by birth, marriage, or adoption to the householder and who is not described by the categories given above. When relationship is not reported for an individual, it is imputed according to the responses for the age and sex for that person while maintaining consistency with responses for other individuals in the household.
An unrelated individual is: (1) a householder living alone or with nonrelatives only, (2) a household member who is not related to the householder, or (3) a person living in group quarters who is not an inmate of an institution.
A family includes a householder and one or more other people living in the same household who are related to the householder by birth, marriage, or adoption. All people in a household who are related to the householder are regarded as members of his or her family. A household can contain only one family for purposes of census tabulations. Not all households contain families since a household may be a group of unrelated people or one person living alone.
Families are classified by type as either a "married-couple family" or an "other family" according to the presence of a spouse. "Other family" is further broken out according to the sex of the householder. The data on family type are based on answers to questions on sex and relationship that were asked on a 100-percent basis.
A family in which the householder and his or her spouse are enumerated as members of the same household.
Male householder, no wife present
A family with a male householder and no spouse of the householder present.
Female householder, no husband present
A family with a female householder and no spouse of the householder present.
A householder living alone or with nonrelatives only.
A measure obtained by dividing the number of people in families by the total number of families (or family householders). In cases where this measure is tabulated by race or Hispanic origin, the race or Hispanic origin refers to that of the householder rather than to the race or Hispanic origin of each individual.
An unmarried-partner household is a household other than a "married-couple household" that includes a householder and an "unmarried partner." An "unmarried partner" can be of the same sex or of the opposite sex of the householder. An "unmarried partner" in an "unmarried-partner household" is an adult who is unrelated to the householder, but shares living quarters and has a close personal relationship with the householder.
The 1990 relationship category "Natural-born or adopted son/daughter" has been replaced by "Natural-born son/daughter" and "Adopted son/daughter." The following categories have been added: "Parent-in-law" and "Son-in-law/daughter-in-law." The 1990 nonrelative category, "Roomer, boarder, foster child" has been replaced by two categories, "Roomer, boarder" and "Foster child." In 2000, foster children had to be in the local governments' foster care system to be so classified. In 1990, foster children were estimated to be those children in households who were not related to the householder nor who had any people over 18 who may have been their parents. In 1990, stepchildren who were adopted by the householder were still classified as stepchildren. In 2000, stepchildren who were legally adopted by the householder were classified as adopted children.
