In the United States, all states with multiple congressional districts are required to revise their district maps following each decennial census to account for population changes. In 2024, most states used the same districts created in the
redistricting cycle following the 2020 census, which were first used in the 2022 elections. However, maps have changed or would change in several states, often due to legal challenges made on the basis of political or racial gerrymandering. As of May 2024, several states have seen challenges to their
congressional district maps that were put in place during the
redistricting cycle brought upon by the results of the 2020 census. In
Alabama, a
special master drew a new map after the
state legislature submitted a map that did not comply with the
Voting Rights Act after the
Supreme Court ruled their original map violated the
Voting Rights Act in
Allen v. Milligan, requiring the creation of a second
predominantly Black district. Similarly, a judge in Georgia ruled that Georgia's maps were illegally racially gerrymandered and the
Georgia General Assembly drew a new map that added a new predominantly Black district. In Louisiana, the Supreme Court's decision not to intervene in
Robinson v. Ardoin led to a second majority Black district being drawn in that state as well, although this map was struck down after a legal challenge by some Louisianans before the
Supreme Court of the United States issued an emergency order allowing the new map to be used in the 2024 elections. On the other hand, Republican legislators in
North Carolina drew a map placing three Democratic incumbents in Republican-leaning districts after the
North Carolina Supreme Court ruled that partisan gerrymandering is not justiciable, which in turn was canceled out by a map passed after a similar state court ruling in
New York that made three highly competitive districts somewhat Democratic-leaning. Other racial gerrymandering cases in
Arkansas,
Florida,
South Carolina,
Tennessee and
Texas and another partisan gerrymandering case in
Utah were not resolved before the filing deadlines for the 2024 Congressional elections in those states; South Carolina's districts were ultimately upheld by the
Supreme Court of the United States over a month after the state's filing deadline.
