Research Tools: U.S. Census 2020 Type of Enumeration Area Viewer Released

From the United States Census:

The U.S. Census Bureau has released the 2020 Type of Enumeration Area (TEA) Viewer. The TEA Viewer is an interactive map application that shows how different geographic areas will be invited to respond to the 2020 Census.

Every household will have the option of responding online, by mail, or by phone. Nearly every household will receive an invitation; 95 percent of households across the nation will receive their census invitation in the mail and almost 5 percent will receive their invitation when a census taker drops it off at their home. The remaining less than 1 percent of areas, mostly remote, will be counted in person by a census taker instead of being invited to respond on their own. Each of these categories is a different TEA.

The Census Bureau used the latest information on local characteristics to assign each area to a TEA; these TEA delineations were released to the public on February 1 during the Census Bureau’s quarterly 2020 Census Program Management Review. The assigned delineations are designed to maximize each area’s participation in the 2020 Census.

The TEA Viewer allows users to explore the interactive map down to the census tract level to see what percentage of housing units are within each TEA. The TEA Viewer is a useful tool for analysis on which neighborhoods and sparsely populated areas can expect to see census takers during the public response phase of the 2020 Census.
