What is a census tract code?
Census tracts are geographic entities within counties (or the statistical equivalent of counties). Census tracts within a county are identified by a 4-digit basic code between 0001 and 9999, and may have a 2-digit suffix ranging from . 01 to . 98; for example, 6059.02.
Are census tract numbers unique?
Census tract numbers range from 1 to 9999 and are unique within a county. The U.S. Census Bureau reserves the basic census tract numbers 9400 to 9499 for census tracts delineated within or to encompass American Indian reservations and offreservation trust lands that exist in multiple states or counties.
How many digits is a census tract?
four digits
Each census tract has a basic census tract number composed of no more than four digits, and may have an optional two-digit decimal suffix. (Leading zeroes appear in electronic media products, but do not appear on the Census Bureau’s maps or in the printed reports.)
Which is bigger census tract or block?
Census tracts are statistical subdivisions of a county that aim to have roughly 4,000 inhabitants. A block group is a subdivision of a census tract and contains a cluster of blocks. Block groups usually have between 250 and 550 housing units. A census block is the smallest geographic census unit.
What is the smallest unit ever used in the census geography hierarchy?
BG
The BG is the smallest geographic entity for which the decennial census tabulates and publishes sample data. It has now largely replaced the earlier enumeration district (ED) as a small-area geographic unit for purposes of data presentation.
How do you get census block level data?
http://www.census.gov/geo/www/tiger/tgrshp2010/tgrshp2010.html allows you to download census blocks by county. Update: the TIGER/shapefiles does not have any demographic data – if that’s what you are looking for you would need American FactFinder.
