United States House of Representatives

The United States House of Representatives, often referred to as the House of Representatives, the U.S. House, or simply the House, is the lower chamber of the United States Congress, with the Senate being the upper chamber. Together they comprise the national bicameral legislature of the United States.

The House's composition was established by Article One of the United States Constitution. The House is composed of representatives who, pursuant to the Uniform Congressional District Act, sit in single member congressional districts allocated to each state on a basis of population as measured by the United States 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, although universal suffrage did not come to effect until after the passage of the 19th Amendment and the Civil Rights Movement. Since 1913, the number of voting representatives has been at 435 pursuant to the Apportionment Act of 1911. The Reapportionment Act of 1929 capped the size of the House at 435. However, the number was temporarily increased in 1959 until 1963 to 437 when Alaska and Hawaii were admitted to the Union.

In addition, five non-voting Delegates represent the District of Columbia and the U.S. territories of Guam, the U.S. Virgin Islands, the Commonwealth of the Northern Mariana Islands, and American Samoa. A non-voting Resident Commissioner, serving a four-year term, represents the Commonwealth of Puerto Rico. As of the 2010 Census, the largest delegation was California, with 53 representatives (to be reduced to 52 in 2023). Seven states have only one representative: Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming..

The House is charged with the passage of federal legislation, known as bills; those of which that are also passed by the Senate are sent to the president for consideration. The House also has exclusive powers: it initiates all revenue bills, impeaches federal officers, and elects the president if no candidate receives a majority of votes in the Electoral College.

The House meets in the south wing of the United States Capitol. The presiding officer is the Speaker of the House, who is elected by the members thereof. Other floor leaders are chosen by the Democratic Caucus or the Republican Conference, depending on whichever party has more voting members.
