United States Census Bureau Demographic Data

A census block group is a geographical unit used by the United States Census Bureau that is between the census tract and the census block. It is the smallest geographical unit for which the bureau publishes sample data, i.e. data that is only collected from a fraction of all households.

Census block groups are identified by a number, usually single digit. This number determines the first digit of all the census blocks that compose the block group; for instance Census Block 2 would have any block numbered 2,000 to 2,999. Block groups generally contain between 600 and 3,000 people, with an optimum size of 1,500 people. Block groups never cross the boundaries of states, counties, or statistically equivalent entities, with the possible exception of block groups delineated by American Indian tribal authorities.
