Redistricting is the process of redrawing the boundaries of election districts to ensure that the people of each district are equally represented. It is done in the United States after the completion of Congressional reapportionment, which decides how many seats each state has in the 435 member House of Representatives. Reapportionment happens following the Decennial Census.
In Minnesota, the state legislature has constitutional responsibility for redistricting Minnesota's Congressional districts, as well as Minnesota Senate and House districts, and Metropolitan Council districts. Local governments are responsible for redistricting other election districts:
County boards are responsible for redistricting county commissioner districts
City councils are responsible for redistricting city wards
School boards are responsible for redistricting board member districts
During the redistricting time period, cities and townships will establish (or reestablish) their precinct boundaries as part of the redistricting process, as will counties that have unorganized territory.
In April, the County Board of Commissioners approved new District boundaries and a new map of those boundaries, which can be seen below.
