Frequently asked questions
How are House seats allocated to states?
The Constitution requires a census every 10 years and guarantees each state at least one House seat. After that, the remaining seats (435 total) are distributed proportionally by population using the "Method of Equal Proportions" (Huntington-Hill method). States that grew faster than the national average gain seats; slower-growing states lose them. After the 2020 census, Texas gained 2, Florida gained 1, and California lost 1 for the first time.
What is the difference between apportionment and redistricting?
Apportionment is the process of deciding how many total House seats each state gets — done by the federal government after each census. Redistricting is the process of drawing the actual geographic boundaries of those districts within a state — done by each state individually, usually by the state legislature or an independent commission, and subject to legal challenges.
Why does every state get exactly 2 senators?
The "Great Compromise" of the 1787 Constitutional Convention resolved the conflict between large and small states. Large states wanted proportional representation; small states wanted equal representation. The compromise created two chambers: the House (proportional by population) and the Senate (equal at 2 per state). This is ensrenched so deeply that Article V of the Constitution explicitly states no state can be deprived of equal suffrage in the Senate without its consent.
Which states have only one House seat?
Seven states have only one at-large representative: Alaska, Delaware, Montana (gained a second seat from 2023), North Dakota, South Dakota, Vermont, and Wyoming. When a state has only one seat, the entire state is one congressional district and the representative runs statewide.
