Block Groups, subdivisions of census tracts, are the smallest geographic areas for which "richer demographics" are developed by the Census Bureau. Block group demographic-economic estimates, based on Census 2010 geography, are annually updated beginning with American Community Survey (ACS) 2010. The latest ACS estimates for these 217,740 areas covering U.S. wall-to-wall are from ACS 2013. The ACS 2014 release date is December 10, 2015. See about considerations in using these data

Analyzing Labor Force Characteristics by Block Group
Examine block groups by ZIP Code ... use the interactive ranking table below to examine national scope labor force characteristics by block group. Block groups are coded by ZIP Code to facilitate use.

The table contains a row for each/every block group area. The block group (BG) geocode is shown in the first column followed by the corresponding ZIP Code area. See notes about about the BG-ZIP Code relationship. For each BG, the table provides the Census 2010 population and selected labor force characteristic characteristics from the ACS 2010 and ACS 2011 5 year estimates. See a description of items below the table.

The BG dataset was developed using the Demographic-Economic Data Extract (DEDE) API tool. See the S&O custom spreadsheet profile that shows the ACS 2011 labor force characteristics for Travis County, TX block group 48-453-001728-3 (among many other items). See the related unemployment characteristics thematic pattern map showing block groups in Austin, TX ZIP Code 78745 (default look-up ZIP Code below the table).

Block Group - ZIP Code Relationship
Block Group areas are often not coterminous with ZIP Code tabulation areas. To develop the BG-ZIP relationship a BG point shapefile was developed based on the geographic centroid of the BG. The ZIP Code (ZCTA) was was assigned to the BG code for the ZCTA containing the BG centroid point.

Census 2010 Race/Ethnicity Block Group Dataset ... downloadable dataset (scroll section)
The Census 2010 Race/Ethnicity Block Group Dataset zip file expands to the CSV structured file "BG_2010_SF1_P003.CSV". The dataset was developed using CV XE APIGateway. The dataset illustrates the capabilities of the APIGateway. Any set of 1990 Census (SF1/SF3), Census 2000 (SF1/SF3), Census 2010, ACS 2010 and later ACS data tabulated by block group may be extracted/integrated using the APIGateway. Register here for more information about the Census 2010 Race/Ethnicity Block Group Dataset download (mention "Census 2010 BG download" in text section).

The CSV file contains an 12 character GEOID census block group geocode and nine additional integer fields described below.

About Block Groups (scroll section)
Tract-Block Group-Block Relationship
Census Block Groups are geographic areas defined by the Census Bureau for a decennial census. Each block group is a set of one or more contiguous blocks. Block groups are the smallest areas for which Census sourced estimates are developed. Block Groups (BGs) are a "mid-range" geography between census blocks and census tracts. For Census 2010 there are 11,078,297 census blocks, 217,740 census block groups and 73,057 census tracts covering the U.S. wall-to-wall. These geographies have a nesting relationship as shown in the graphic at right. For any given county, Census 2000 and Census 2010 vintage block group areas might differ significantly in terms of boundary, geocode and relationship to associated census blocks and census tracts.

The census block is the lowest level geographic area for which Census 2010 data are tabulated. The census block group is the smallest geographic area for which American Community Survey (ACS) data are tabulated (estimated).

No Census 2010 Richer Demographics. As with all Census 2010 geographic areas, census block group tabulations include Census 2000 "short-form" type subject matter. There are no "richer demographics" Census 2010 data owing to use of the reduced scope questionnaire. In contrast, annual ACS block group estimates of richer demographic are available. The first ACS data for Census 2010 BG geography/boundaries are the ACS 2010 5-year estimates (release date December 2011). These estimates are based on the survey period 2006 through 2010 and thus measures centric to mid-2008.

Comparing Census 2000 to ACS BG Demographics. The first ACS BG estimates were produced as a part of the 2009 ACS 5-year estimates (for the survey period 2005-2009; measures centric to mid-2007). The 2009 ACS BG data (released December 2010) are estimates for Census 2000 vintage block group codes/boundaries. These are the only BG level estimates available to examine demographic change and patterns since Census 2000 (as both programs use the same BG codes/boundaries). The 2010 ACS shifts to use of the Census 2010 codes/boundaries. See also Census 2010 Demographics for Census 2000 Geography.
