PRB has produced an updated series of tables and maps identifying neighborhoods with a very high risk of undercounting young children in combination with low 2020 Census self-response rates. The new data and maps are based on response rates as of July 16.

We also added new functionality to the maps to make data for different racial/ethnic groups more accessible. Use the filters in the upper right corner of each map to display census tracts where different racial/ethnic groups make up the majority of children under age 5.

Here is a sample map of the Washington, DC area, displaying undercount risk and self-response rates in census tracts where the majority of children under age 5 are Black.

In some neighborhoods, no single racial/ethnic group constitutes a majority of the young child population. We classified these census tracts as “No Majority.” Use the tract-level database to access more detailed information about the racial/ethnic composition of the young child population in each neighborhood.
