How many members are in the U.S. Senate?

The United States Senate is composed of 100 members. This structure is established by the U.S. Constitution, which designates that each state is represented by two senators, regardless of population size. As there are 50 states in the union, this results in a total of 100 senators. This system was designed to ensure equal representation of each state in the legislature, balancing the interests of both larger and smaller states. In contrast, the U.S. House of Representatives has 435 members, which is based on the population of each state, further highlighting the distinct roles and structures of the two chambers of Congress.
