How many voting members are in the House of Representatives?

The House of Representatives is made up of 435 voting members, a number established by law. This composition reflects the population distribution across the states, with each state's representation based on its population relative to others. The total of 435 was set in the Reapportionment Act of 1929, which aimed to ensure that representation in Congress remained fair and responsive to population changes in the U.S. States gain or lose representatives based on shifts in population, as determined by the decennial census. This structure is crucial for maintaining a balanced representation in the federal legislative process.
