List of United States congressional districts

Congressional districts in the United States are special areas that help choose members for the United States House of Representatives. There are 435 seats in the House, and each one represents about 761,169 people, based on the 2020 United States census. This number of seats has been used since 1913, except for a short time when it went up to 437 after Alaska and Hawaii joined the country.

The Bureau of the Census counts the country’s people every ten years, and this helps decide how many districts each state gets. The 2022 elections were the first to use the new districts from the 2020 United States census.

Each state draws its own district lines. Some smaller states, like Alaska, Delaware, North Dakota, South Dakota, Vermont, and Wyoming, have just one district for everyone in the state. When the number of districts changes or when the people in a district change a lot, the lines are redrawn. Each district should have about the same number of people.

Delimitation

In the United States, state legislatures mainly decide how to draw the lines for congressional districts. This process, called redistricting, happens after every ten-year census. Most states let their legislature create the redistricting plan, but six states (Alaska, Delaware, North Dakota, South Dakota, Vermont and Wyoming) choose one representative for the whole state instead.
