how many members of congress are there

There are 535 voting members of the U.S. Congress: 100 senators and 435 representatives. If you include the non-voting delegates and the resident commissioner in the House, the total membership count rises to 541 (435 voting representatives plus 6 non-voting members, plus 100 senators).

Basic breakdown

• Senate : 100 members, two from each of the 50 states.

• House of Representatives (voting) : 435 seats, apportioned among the states by population.

• Non‑voting House members : 6 (from Washington, D.C., Puerto Rico, Guam, American Samoa, the U.S. Virgin Islands, and the Northern Mariana Islands).

Why 435 in the House?

• The House was expanded over time as the population grew but was capped at 435 seats by law in 1911, a limit that still applies today.

• After each census, seats are re-apportioned among states, but the total stays at 435, which drives periodic debates about whether the House should be enlarged to reflect population growth.

Current Congress context

• The current 119th Congress, which convened in January 2026, still operates with 100 senators and a 435-seat House, though there can be temporary vacancies due to resignations, deaths, or delayed elections.

• Even when some seats are vacant, the authorized size remains 535 voting members, and House control can hinge on just a few filled or unfilled seats.
