How many members are there in the House of Representatives?

The House of Representatives consists of 435 members. This number is established by law and is based on the apportionment of representatives among the states, which is determined by the population of each state. The total of 435 representatives was set by the Reapportionment Act of 1929, and it remains unchanged unless a new law is enacted to alter that number.

In contrast, the other options reflect incorrect totals. For instance, the Senate is made up of 100 members, with each state represented by two senators, regardless of population. The options of 200 or 535 members do not correspond to any specific structure within the U.S. Congress: 535 would be the total number of members when both the House and the Senate are combined, but when referring specifically to the House of Representatives, the correct figure is 435.
