2020 Census Tracts (Census/TIGER)

This is the 2020 vintage of the 2020 TIGER/Line Census Tracts. Census tracts are small, relatively permanent statistical subdivisions of a county or equivalent entity. The primary purpose of census tracts is to provide a stable set of geographic units for the presentation of census data and comparison back to previous decennial censuses. Census tracts generally have a population size between 1,200 and 8,000 people, with an optimum size of 4,000 people. When first delineated, census tracts were designed to be homogeneous with respect to population characteristics, economic status, and living conditions. The spatial size of census tracts varies widely depending on the density of settlement. Date: 1/21/2021 Update: Irregular. While Census boundaries are updated every 10 years, the Census Bureau makes annual corrections to the geographies as needed. These updates are usually minor and BMC reviews them every few years.
