2000 Definition:
Household-- A household includes all the persons who
occupy a housing unit. A housing unit is a house, an apartment, a mobile home, a
group of rooms, or a single room that is occupied (or if vacant, is intended for
occupancy) as separate living quarters. Separate living quarters are those in
which the occupants live and eat separately from any other persons in the
building and which 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 persons who share living arrangements. People not living in a
household are classified as living in group quarters.
Persons Per Household-- Obtained by dividing the number of persons in
households by the number of households (or householders) since the number of
households equals the number of householders.
Also referred to as “Average household size.”
Family Household-- A family household includes a householder and
one or more 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 census
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 census tabulations. Not
all households contain families since a household may comprise a group of
unrelated persons or one person living alone.
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 on a
100-percent basis.
