Census Block Group Program for the 2010 Decennial Census-Final Criteria

Block groups are statistical geographic divisions of a census tract, defined for the tabulation and presentation of decennial census data. Block groups also will be used to tabulate and present period estimates from the American Community Survey (ACS) \1\ after 2010. Block groups provide the geographic framework within which the Bureau of the Census (Census Bureau) defines census blocks. Each block group comprises a reasonably compact and contiguous cluster of census blocks; up to nine block groups can be contained within a single census tract. ---------------------------------------------------------------------------
