Congressional districts in the United States are electoral divisions for the purpose of electing members of the United States House of Representatives. The number of voting seats in the House of Representatives is currently set at 435, with each one representing an average of 761,179 people following the 2020 United States census. The number of voting seats has applied since 1913, excluding a temporary increase to 437 after the admissions of Alaska and Hawaii. The total number of state members is capped by the Reapportionment Act of 1929. In addition, each of the five inhabited U.S. territories and the federal district of Washington, D. C., sends a non-voting delegate to the House of Representatives.
