Census Tract Data for CDBG Application

definitions
Definitions
  • Census tract: A small, relatively permanent statistical subdivision of a county. Census tract boundaries normally follow visible features, but may follow governmental unit boundaries and other non-visible features in some instances; they always nest within counties. Designed to be relatively homogeneous units with respect to population characteristics, economic status, and living conditions at the time of establishment, census tracts average about 4,000 inhabitants. They may be split by any sub-county geographic entity.
  • Block group: A subdivision of a census tract (or, prior to 2000, a block numbering area), a block group is the smallest geographic unit for which the Census Bureau tabulates sample data. A block group consists of all the blocks within a census tract with the same beginning number.
  • Block: a subdivision of a census tract, a block is the smallest geographic unit for which the Census Bureau tabulates 100-percent data. Many blocks correspond to individual city blocks bounded by streets, but blocks - especially in rural areas - may include many square miles and may have some boundaries that are not streets.

factfinder reference map options
FactFinder: Reference Map Options
  • Use the options on the left side of the screen to reposition by street address or ZIP code.
  • Use the "Recenter and zoom in" and Zoom button features to display the desired area. You may have to Recenter and Zoom In several times to find the community of interest to you or to have readable street names. Tract numbers, boundaries, and street names will all be displayed when you are at an appropriate Zoom level. (Having the Zoom button on the second, third, or fourth level from the right often works well for an urban area).
  • The legend on the left side of the screen will clarify which boundaries and labels are for census tracts and which are for block groups (smaller areas within a tract).
  • Use the “Change Boundaries and Features” option at the upper left to change the information shown on the map.
