House of Representatives
The lower chamber of the United States Congress, in which each state is apportioned voting Members roughly in proportion to its population, as counted in the decennial census. Since 1929 its voting membership has been fixed at 435, every Member elected to a two-year term.

Example: Under Article I, Section 2 of the Constitution and 2 U.S.C. 2, each state receives at least one Representative and the remaining seats are reapportioned after each census, which is why fast-growing states gained seats after the 2020 census and slower-growing states lost them.
Common misconception: The Constitution sets the number of Representatives at 435. It does not; Congress fixed that number by statute in 1929, and it could be changed by ordinary legislation.
