ongress is composed of 541 individuals from the 50 states, the District of Columbia,
Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa, and the Northern Mariana
C Islands.1 This count assumes that no seat is temporarily vacant.2 The following is a profile
of the 111th Congress.3
Party Breakdown
In the 111th Congress, the current party alignments are 261 Democrats in the House of
Representatives (including five Delegates and the Resident Commissioner) and 180 Republicans.
The Senate has 57 Democrats; two Independents, who caucus with the Democrats, and 41
Republicans.
Age
The average age of members of the 111th Congress is among the highest of any Congress in recent
U.S. history.4 The average age of Senators at the beginning of the 111th Congress was 63.1 years,
approximately 1.5 years greater than that of the 110th Congress (61.7 years) and three years older
than that of Senators in the 109th Congress (60.1 years).
At the beginning of the 111th Congress, the average age of members of the House, including
Delegates and the Resident Commissioner, was 57.2 years, over a year older than that of
Representatives in the 110th Congress (55.9 years), and almost two years older than that of
Representatives in the 109th Congress (55.1 years). The average age of all members in both
houses is 58.2 years.
At the beginning of the 111th Congress, the average age of new members of the House, including
a Delegate and the Resident Commissioner, was 49.8 years. The average age of new Senators was

1 This figure includes 100 Senators, 435 Representatives, five delegates (from the District of Columbia, Guam,
American Samoa, the U.S. Virgin Islands, and the Northern Mariana Islands), and one Resident Commissioner from
Puerto Rico. The 111th Congress is the first one in which the Northern Mariana Islands have had a delegate. Note that
since 1789, 11,909 individuals (not including Delegates and Resident Commissioners) have served in Congress: 9,991
only in the House, 1,268 only in the Senate, and 650 in both houses.
2 Currently, there are no House vacancies or Senate vacancies. For information on all special elections and
appointments to fill vacancies in the 111th Congress, refer to http://crs.gov/resources/Pages/Congress_111.aspx. This

fill a vacancy.
