How many members are there in the House of Representatives?

The House of Representatives is composed of 435 members. This number is established by law and has been in effect since 1911, with adjustments made to reflect population changes through a process known as apportionment following each U.S. Census. Members of the House serve two-year terms, and the total number of representatives is divided among the states in proportion to their population. This ensures that larger states have more representatives, while smaller states have fewer, maintaining a balance in representation.

The other options reflect incorrect totals based on different contexts. For instance, there are 100 senators in the Senate, two for each state, which could lead to confusion. The number 200 is not representative of any significant body in the U.S. Congress, nor does it reflect any modern legislative body. Likewise, 500 is not a correct count for any legislative assembly in the United States. Therefore, the correct answer of 435 underscores the actual composition of the House and its structure within the U.S. government.
