The number of voting representatives in the House is fixed by law at no more than 435, proportionally representing the population of the 50 states.
In the U.S., Congress includes two âhouses:â the Senate and the House of Representatives. There are 100 senators, and 435 representatives. Sometimes people are not careful about the distinction, and say âCongressâ or âCongressmanâ when they mean specifically the House and not the Senate.
