There are 535 voting members in the U.S. Congress. Each state elects two senators, while the number of people who represent each state in the U.S. House of Representatives differs based on the state's population. The total number of representatives is set by law at 435; the law has been in place since 1911.
The U.S. Constitution sets the number of senators per state. Representatives are a matter of public law, which is subject to change. California has 53 representatives in 2014, which is the greatest number from any state, while seven states have only one member in the U.S. House of Representatives. As of 2014, 20 of the 100 senators are female, and 80 of the 435 representatives are female. Senators serve six-year terms with alternating elections so that no more than one-third of senators hold an election in one cycle. Representatives hold two-year terms.
