Background on Census-Defined Areas
The Census Bureau provides data for many geographic areas, including counties, cities, census tracts, block groups, and blocks. Seattle is divided into 124 census tracts and extends slightly into two additional census tracts. Seattle's census tracts are divided into 570 block groups. The block groups are further divided into 9,223 blocks. Blocks are the smallest geographic areas used by the Census Bureau. Blocks are nested in block groups which are, in turn, nested in census tracts. (See also Census 2000 data for locally defined areas.)
