A U.S. Senator represents all the people of their entire state. Each state, regardless of population size, elects two senators who serve six-year terms. Unlike members of the House of Representatives, who represent individual districts within a state, senators represent the whole state and all its residents

. Senators are elected by a statewide popular vote and must meet certain requirements: they must be at least 30 years old, have been a U.S. citizen for at least nine years, and be a resident of the state they represent at the time of election

. In summary, a U.S. Senator represents the entire population of their state, serving as one of two senators per state in the Senate
