What is a census block ID?
Every Census Block Group has a unique 12-digit FIPS code. The Block Group’s unique identifier is the 12th digit of the FIPS Code. This number determines the first digit of all the census blocks contained within a block group. For instance, census Block Group 2 includes any block numbered 2000 to 2999.
How many digits is a census tract number?
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.)
How to find census block codes by state?
Below are links to lists of the 15-digit census block FIPS codes for each U.S. state/territory in two formats: (1) a CSV file listing all of the census blocks in a state, or (2) an Excel file with a worksheet for each county in the state that lists the census blocks in that county. The block codes are based on the 2010 Census.
Where can I find the census geographic entities for an address?
You can also find the census geographic entities for an address using the “Find Geographies Using…” option. The “Find Geographies Using…” option returns the state, county, census tract, and block for each address. Additional geographies are available using the instructions under Documentation below.
How is the location of a census tract determined?
The state, county, census tract, and block codes are returned. The geocoder takes the address and determines the approximate location offset from the street centerline.
Where does the Geocoder for a census come from?
The information in the geocoder comes from our MAF/TIGER database, which holds our geographic information used for censuses and surveys. The address ranges used in the geocoder are the same address ranges that can be found in the TIGER/Line Shapefiles which are derived from the Master Address File (MAF).
