How are census tracts determined?

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. The decimal point separating the 4-digit basic tract code from the 2-digit suffix is shown in U.S. Census Bureau printed reports and maps.

Who is tallied in the census?

How are block groups determined for the 2020 census?

General Principles and Criteria for Block Groups for the 2020 Census 1. Block groups are statistical geographic subdivisions of a census tract and are the smallest geographic areas for which the Census Bureau provides sample data, primarily from the ACS 5-year period estimates.

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.

Can a block group cross a county boundary?
