Family Type – A family consists of 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 family household may contain people not related to the householder, but those
people are not included as part of the householder’s family in tabulations. Thus, the number
of family households is equal to the number of families, but family households may include
more members than do families. A household can contain only one family for purposes of
tabulations. Not all households contain families since a household may be comprised of a
group of unrelated people or of one person living alone – these are called nonfamily
Families are classified by type as either a “married-couple family” or “other family” according to the sex of the householder and the presence of relatives. The data on family type are based on answers to questions on sex and relationship that were asked of all people.
Married-Couple Family – A family in which the householder and his or her spouse
are listed as members of the same household.
Male Householder, No Wife Present – A family with a male householder and no spouse of householder present.
Female Householder, No Husband Present – A family with a female householder and no spouse of householder present.
Householder – The data on relationship to householder were derived from answers to
Question 2, which was asked of all people in housing units. One person in each household is
designated as the householder. In most cases, this is the person, or one of the people, in
whose name the home is owned, being bought, or rented and who is listed on line one of the
survey questionnaire. If there is no such person in the household, any adult household
member 15 years old and over could be designated as the householder.
Households are classified by type according to the sex of the householder and the presence of
relatives. Two types of householders are distinguished: a family householder and a nonfamily
householder. A family householder is a householder living with one or more
individuals related to him or her by birth, marriage, or adoption. The householder and all
people in the household related to him or her are family members. A non-family householder
is a householder living alone or with non-relatives only.
