What is the length of a single term for a u. s. senator?

Two senators are elected from each state, but the number of House members varies per state. There are 435 members of the House of Representatives. Representation by state is determined by the U.S. Census population statistics. States are divided into districts that contain an equivalent number of people. Each state is guaranteed at least one representative.

A senator must be at least 30 years old, and members of the House of Representatives must be at least 25 years old.
