Definition of Terms


Includes all the people who occupy a housing unit; whether it is a house, an apartment, a mobile home, a group of rooms, or a single room intended for separate occupancy. The count of households equals the count of occupied housing units.

Persons Per Household:

The number of persons in households divided by the number of households (or householders).


A householder and one or more other persons living in the same household who are related to the householder by birth, marriage, or adoption. All persons in a household who are related to the householder are regarded as members of his or her family. For census tabulations, a household can contain only one family. Not all households contain families since a household may comprise a group of unrelated persons or one person living alone.

Married-Couple Family:

A family in which the householder and his or her spouse are enumerated as members of the same household.

Other Family:

Either, Male Householder, No Wife Present or Female Householder, No Husband Present.
