Missouri's congressional districts

The State of Missouri is currently divided into eight congressional districts, with each one being represented by a member of the United States House of Representatives. The current dean of the Missouri delegation is Representative Sam Graves (MO-6) of the Republican Party. He has served in the House since 2001 and is sixty-one years old.

Due to the 2010 census, Missouri lost a congressional seat in 2013. The biggest impact has been in the 3rd congressional district, which includes portions of St. Louis that had undergone large population losses in the census. The district effectively became part of the 1st district. The largely rural 9th district, which also suffered population decreases and was dissolved as well, became part of the 6th district north of the Missouri River as well as part of a redrawn more rural 3rd district south of the river.^[1]

After the 2020 census, the number of congressional districts stayed the same.
