Group Quarters Population
Persons who reside in places such as nursing homes, military facilities, or rooming houses. Two general categories of persons in group quarters are recognized: 1) inmates or residents of institutions, and 2) other persons in noninstitutional group quarters.

Hispanic
Persons of Hispanic Origin identifying themselves generally as Latino, Spanish, Spanish-American, Hispanic, Hispano, etc. Origin can be viewed as ancestry, nationality group, lineage, or country of birth of the person or the person's parents or ancestors.

Household Population
The difference between total population and group quarters' population. The term includes all persons living in individual housing units. Housing units include attached or detached single units, units in a multiple-unit building, and other miscellaneous units such as mobile homes.

Household Size

Household
Household is another term for an occupied dwelling unit. A household includes all persons who occupy a housing unit. A housing unit is a group of rooms or a single room occupied as separate living quarters where occupants live separately from other persons in the building and have direct access from outside the building or through a common hall.

A household can include more than one family.

Mean Household Income

This figure is calculated by dividing total personal income, as estimated by ABAG, by the total number of households. Total personal income includes estimates of wages and salaries, income from interest, dividends, or rental income, and income obtained through transfer payments, such as social security or public assistance. The income numbers are based upon the definition of income as reported in Census 2000. In Projections 2007, mean (average) household income is expressed in 2005 dollars.
