Minnesota's 4th congressional district

Minnesota's 4th congressional district covers nearly all of Ramsey County and part of Washington County. It includes all of St. Paul and most of its northern and eastern suburbs, including Woodbury, Blaine, Roseville, and Maplewood. The district is solidly Democratic, with a CPVI of D+18. It is currently represented by Betty McCollum of the Minnesota Democratic-Farmer-Labor Party (DFL). The DFL has held the seat without interruption since 1949 and all but one term (1947–1949) since the merger of the Democratic and Farmer-Labor Parties.

One of the most diverse congressional districts in Minnesota, the 4th district has the second-largest immigrant population of Minnesota's congressional districts, at 15% of the population. The largest countries of origin are Laos, Thailand, Myanmar, Mexico, India, Ethiopia, and Somalia, with immigrant populations largely concentrated in Saint Paul. The 4th district has the highest percentage of Hmong residents of any district in the United States, at 6% of the population.
