The Senate chamber is located in the north wing of the Capitol, in Washington, D.C. The composition and powers of the Senate are established by Article One of the United States Constitution. The Senate is composed of senators, each of whom represents a single state in its entirety. Each state, regardless of its population size, is equally represented by two senators who serve staggered terms of six years. There being at present 50 states in the Union, there are presently 100 senators.
The United States House of Representatives is the lower chamber of the United States Congress, the Senate being the upper chamber. Together they compose the legislature of the United States. The composition of the House is established by Article One of the United States Constitution. The House is composed of Representatives who sit in congressional districts that are allocated to each of the 50 states on a basis of population as measured by the U.S. Census, with each district entitled to one representative. Since its inception in 1789, all Representatives have been directly elected. The total number of voting representatives is fixed by law at 435.
