| Block group | Census | 1: A statistical subdivision of a census tract (or, prior to Census 2000, a block numbering area). A BG consists of all tabulation blocks whose numbers begin with the same digit in a census tract. For example, for Census 2000, BG 3 within a census tract includes all blocks numbered from 3000 to 3999. (A few BGs consist of a single block.) BGs generally contain between 300 and 3,000 people, with an optimum size of 1,500 people. The BG is the lowest-level geographic entity for which the U. S. Census Bureau tabulates sample data from a decennial census. See tribal block group. (references) | |
| 2: A subdivision of a census tract (or, prior to 2000, a block numbering area), a block group is the smallest geographic unit for which the Census Bureau tabulates sample data. A block group consists of all the blocks within a census tract with the same beginning number. Example: block group 3 consists of all blocks within a 2000 census tract numbering from 3000 to 3999. In 1990, block group 3 consisted of all blocks numbered from 301 to 399Z. Related terms: Census block, Census geography, Census tract, Sample data. (references) | |||
| Block group | Transportation | A small population area that the U.S. Census Bureau uses to measure and record demographic characteristics. The population of a block group typically ranges from 600 to 3,000 people and is designed to reflect homogeneous living conditions, economic status, and population characteristics. Block group boundaries follow visible and identifiable features, such as roads, canals, railroads, and above-ground high-tension power lines. (references) | |
| Census block group | Transportation | The smallest geographic unit for which the U.S. Census provides information on racial background, ethnic heritage, and household income. (references) | |
| Tribal Block Group | Census | 1: A subdivision of a tribal census tract, a tribal block group is the smallest geographic unit for which the Census Bureau tabulates sample data. Tribal BGs are delineated by American Indian tribal participants or the Census Bureau, and average about 1,000 people. A tribal BG consists of all the census blocks within a tribal census tract with the same beginning number. Example: Tribal BG 3 within a tribal census tract consists of all blocks numbered from 3000 to 3999. In situations where an American Indian reservation or trust land crosses county or state lines, the same tribal BG number (within a tribal census tract) may be assigned on both sides of the county/state line. (references) | |
| 2: A block group within a tribal census tract. Where a census tract numbered in the 9400 series crosses a county line, a tribal block group may be located on both sides of that boundary. See block group, tribal census tract. (references) | |||
