Missouri currently sends 8 representatives to the U.S. House of Representatives, with the delegation in the 118th Congress comprising 6 Republicans and 2 Democrats, led by Sam Graves (R-MO-6) as its dean, who has served since 2001. After the 2010 census, Missouri lost a seat, shrinking from 9 to 8, which forced the dissolution of the rural 9th district and dramatically redrew the 3rd district, transferring its population-losing St. Louis portions into the 1st district. The 2020 census did not change the state's allotment, keeping it at 8 districts. Over the decades, Missouri has shed many districts due to slower population growth relative to the nation, with obsolete districts including the 10th (since 1980), 11th (since 1960), 12th and 13th (since 1950), and several others from the 1930s, plus an at-large seat that ended in 1935. The article also provides a chronological table of district boundary maps from 1973 to 2013, illustrating the significant redistricting shifts, particularly around St. Louis and rural areas.
