how often are members of the house of representatives elected

Members of the U.S. House of Representatives are elected every two years. All 435 seats are contested in these elections, which occur during both presidential and midterm election years. This biennial election cycle is established by the U.S. Constitution to ensure that representatives remain accountable to their constituents and responsive to public will. Special elections may also be held to fill vacancies if a member dies or resigns before their term ends.
