Congressional districts are the 435 areas from which people are elected to the U.S. House of Representatives. After the apportionment of congressional seats among the states based on decennial census population counts, each state with multiple seats is responsible for establishing congressional districts for the purpose of electing representatives. The boundaries and numbers shown for the congressional districts are those specified in the state laws and/or court orders establishing the districts within each state.
This wall map depicts congressional district boundaries in effect for the 113th Congress of the United States (January 2013-2015). The map includes county names and boundaries for each state, the District of Columbia, Puerto Rico, American Samoa, Guam, the Commonwealth of the Northern Mariana Islands, and U.S. Virgin Islands. The map also includes a listing of the names of all members of the 113th Congress, as of January 22, 2013.
