How many members are there in the House of Representatives?

The House of Representatives is composed of 435 members. This number has been set since the Reapportionment Act of 1929, which established a fixed total of representatives to ensure a manageable size for legislative deliberation and governance. Each member represents a congressional district, and these districts are apportioned among the states based on population, as determined by the decennial census.

The other figures provided do not reflect the actual number of members. For instance, 400, 450, and 500 would exceed the established limit and would lead to impracticalities in representation and legislative processes. The decision to maintain 435 members allows for a balance between adequate representation and effective functioning of the legislative body.
