Following the 2000 U.S. Census and associated realignment of Colorado congressional districts, the 2nd congressional district consisted of Broomfield, Clear Creek, Eagle, Gilpin, Grand, and Summit counties, as well as portions of Adams, Boulder, Jefferson, and Weld counties.
Following the 2010 U.S. Census and associated realignment of Colorado congressional districts, the 2nd congressional district consisted of Broomfield, Clear Creek, Gilpin, Grand, Larimer and Summit counties; most of Boulder and Jefferson counties; and portions of Eagle and Park counties.
