US House
The United States House of Representatives is the lower house of the United States Congress, with the Senate being the upper house. Together they compose the national bicameral legislature of the United States. The House's composition is established by Article One of the United States Constitution. The House is composed of representatives who sit in congressional districts allocated to each state on a basis of population as measured by the U.S. Census, with each district having one representative, provided that each state is entitled to at least one. Since its inception in 1789, all representatives have been directly elected. The number of voting representatives is fixed by law at 435. If enacted, the DC Admission Act would permanently increase the number of representatives to 436. In addition, there are currently six non-voting members, bringing the total membership of the House of Representatives to 441 or fewer with vacancies.
