Supplementary notes
According to the definition by the U.S. Census Bureau a household "includes all of the people who occupy a housing unit. 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."
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."
