In 2 states, 1 in 20 residents missed during US head count

Around 1 in 20 residents in Arkansas and Tennessee were missed during the 2020 census, and four other U.S. states had significant undercounts of their populations which could shortchange them of federal funding in the current decade, according to figures from a survey the U.S. Census Bureau released Thursday.

In Florida, and Texas, undercounts appear to have cost them congressional seats too.

On the flip side, residents in eight states were overcounted during the once-a-decade head count that is used to allocate political power and federal funding. In Minnesota and Rhode Island, overcounts appear to have helped save them from losing congressional seats.

In the remaining 36 states and the District of Columbia, the overcounts and undercounts were not statistically significant. Undercounts signal people were missed. Overcounts suggest they were counted more than once, as for example, children of divorced parents who share custody or people with vacation homes.

The figures released Thursday from the Post-Enumeration Survey serve as a report card on how well residents in the 50 states and District of Columbia were counted during a census that faced unprecedented obstacles from a pandemic, hurricanes and wildfires, social unrest and political interference by the Trump administration.

States that did a better job of getting residents counted scored greater Electoral College and congressional representation, or did not lose expected seats in the House of Representatives. They also are now better positioned for the annual distribution of $1.5 trillion in federal funding in the coming decade.

Nothing can be done at this point to change how many congressional seats are allocated among the states, and neither can the data used for redrawing congressional districts be adjusted.
