The United States House of Representatives is composed of 435 voting members, each elected from a congressional district in the 50 states. Membership is apportioned among the states according to population as measured by the decennial census; the largest single state delegation is California, which currently has 53 districts. In addition to the voting membership there are several non‑voting delegates and a Resident Commissioner who represent territories and the District of Columbia.
Composition and party distribution
Members of the House are elected to two‑year terms, with all seats contested at regular biennial elections. Party control and the numerical composition of the House can change with each election and through special elections held to fill vacancies. As of the current Congress, one of the major parties holds the largest number of seats, and party leaders in the House set the legislative agenda, committee assignments and much of the chamber's daily business.
Non‑voting members and special roles
Besides the 435 voting representatives there are non‑voting delegates and the Resident Commissioner from Puerto Rico. These members may serve on committees and take part in debates, but they do not cast final floor votes on legislation. The Resident Commissioner's term differs from other delegates in that it is longer than the standard two years.
How the list is organized and what it includes
Standard published lists of current members typically include: state and district, member name, party affiliation, date first sworn into the House, current committee assignments and leadership positions, and contact information. Lists may be sorted by state, by seniority, or alphabetically. For many users the most useful form is a state-by-state roster showing each district's representative and party.
Changes in membership and how to follow updates
Membership can change between general elections through resignations, deaths, expulsions or appointments to other offices; vacancies are usually filled by special election according to state law. For the most reliable and current roster consult the official House directory and the Clerk of the House, which maintain updated member information, voting records and committee rosters: Official House directory and Clerk of the House resources. Nonpartisan and party trackers also publish consolidated lists and maps: external trackers and encyclopedic summaries.
Understanding the list of current members is essential for tracking legislation, constituent services and the balance of power in Congress. Because membership numbers and party advantage can shift, always consult official sources for the latest changes before citing counts or delegations.
