How many members are in the House of Representatives?

The House of Representatives consists of 435 members, which is established by the permanent apportionment act of 1929. This number reflects the total representation allocated to the states based on population, with each state having at least one representative regardless of its population size.

The distribution of these members can change every ten years following the national census, as it is intended to ensure that representation in the House reflects the demographic shifts within the country. The Constitution originally allowed for a number of representatives per state, but this fixed total of 435 has remained constant for several decades. This structure helps hold the legislative branch accountable to the electorate by ensuring that representation scales with population changes.

In contrast, the other numbers presented—100, 300, and 500—do not align with the established structure of the House. The House's counterpart, the Senate, has 100 members, which may lead to some confusion, but the definitive and current total for the House is indeed 435.
