The term for the people represented by a member of Congress is their "constituents." Specifically, for members of the House of Representatives, these constituents are the people living in the member's congressional district, which is a defined geographic area within a state. Each representative serves the people of their specific congressional district

. In the Senate, members represent the entire state rather than a district, so their constituents are all the people of that state

. Thus:

• For a House member, the people they represent are called their constituents from their congressional district.
• For a Senator, the people they represent are their constituents from the entire state.
