Footnotes:

  1. 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. 
  2. 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.
  3. Nonfamily households consist of a single person living alone or two or more persons occupying a housing unit who are not related by birth, marriage or adoption.
  4. Unmarried couples include a person who is not related to the householder, who shares living quarters, and who has a close personal relationship with the householder.  Unmarried couples can be of the opposite sex or the same sex.
  5. Multiply figure by 100 for percentage.
