Households are classified by type according to sex of the householder and the presence of relatives based on questions asked on sex and household relationship. This item was determined on a complete-count basis.
A household including a family (See: "Family"). A family household may also include nonrelatives living with the family. The following subcategories are frequently provided: married-couple family; family with male householder, no wife present; and family with female householder, no husband present (see: "Family Type").
A household consisting of a person living alone or of a householder living with other unrelated individuals (see: Unrelated Individual).
In 1970, nonfamily households were termed primary individual households, a primary individual being a person living alone or the head of a household in which no relatives were present.
