Geographic Component
A geographic component is the portion of a geographic area (e.g., Alabama) that meets a location-based test such as "in a metropolitan area" or "in a rural place". For example, a geographic component of "in metropolitan area" for Texas combines the land area of El Paso, TX MSA, San Antonio, TX MSA and all other metropolitan areas in Texas into a single collective identity.
The Census Bureau recognizes about 100 different geographic components, with most focusing on urban/rural or metropolitan/non-metropolitan distinctions. Geographic components are only available for some types of geographic areas (e.g., State, Region). And the specific geographic components available for one geographic type may be different from those available for another geographic type.
A two-character code is associated with each geographic component. See census- or survey-specific code lists for the American Community Survey and Census 2000.

Group quarters (GQ)
The Census Bureau classifies all people not living in households as living in group quarters. There are two types of group quarters: institutional (for example, correctional facilities, nursing homes, and mental hospitals) and non-institutional (for example, college dormitories, military barracks, group homes, missions, and shelters).
Related term: Household
Group quarters population
Includes all people not living in households. This term includes those people residing in group quarters as of the date on which a particular survey was conducted. Two general categories of people in group quarters are recognized: 1) the institutionalized population which includes people under formally authorized supervised care or custody in institutions at the time of enumeration (such as correctional institutions, nursing homes, and juvenile institutions) and 2) the noninstitutionalized population which includes all people who live in group quarters other than institutions (such as college dormitories, military quarters, and group homes). The noninstitutionalized population includes all people who live in group quarters other than institutions.
