A note about Census Geography

Census Geography: (state, county, tract, block-group, block). Note: Data is also aggregated for "place" (cities and towns) and other political/administrative divisions such as census county divisions (ccd) and municipal civil divisions (mcd).

Please Note: Many statistics are collected only through a sample count. This means that there are fewer statistics available for the smaller geographies. In addition, some data is suppressed for very small geographic areas, e.g. blocks, to protect individual privacy.

See: the US Census guide, for additional information about the US census.
