The U.S. House of Representatives has 435 voting members, plus 6 non‑voting delegates from Washington, D.C. and U.S. territories, for a total of 441 people when all seats are filled.

Core numbers

  • Voting members : 435 representatives allocated among the 50 states by population.
  • Non‑voting members : 6 (5 delegates from territories and 1 resident commissioner from Puerto Rico).
  • Vacancies change over time : Because of deaths, resignations, or contested elections, there can be temporary vacancies, so the number of people actually serving on a given day can be slightly below 435.

How this works in practice

  • The Constitution sets up the House to represent people by population, and federal law currently caps the number of voting seats at 435.
  • On top of those, D.C., Puerto Rico, American Samoa, Guam, the U.S. Virgin Islands, and the Northern Mariana Islands send non‑voting delegates who can serve on committees and speak on the floor but generally cannot vote on final passage of bills.

TL;DR : When someone asks “how many people are in the House of Representatives,” the standard answer is 435 voting members, with 441 total including the 6 non‑voting delegates when every seat is filled.
