Congressional Apportionment

There are 435 seats in the U.S. House of Representatives. Those seats are divided, or apportioned, among the states based on each state's population. According to the U.S. Constitution, a census of the population of each state shall be conducted once every ten years to ensure that the representation of each state is apportioned fairly. The U.S. Census Bureau conducted the 2010 Census to determine the population of each state. Using that data, the Census Bureau will then calculate the number of representatives per state. The representation of each state must reflect the relative size of its population as compared to other states and every state must have at least one seat. Title 13, U.S. Code requires that the apportionment population counts for each state be delivered to the President within 9 months of the census date. In the 2010 Census and most 20th century censuses, the census date has been April 1, meaning that the Office of the President received the counts by December 31 of each census year. The apportionment process does not affect U.S. Senate seats since each state has two senators, regardless of population.

Minnesota has had eight congressional representatives since 1960. While Minnesota has gained population since the last census, the rate of population growth has been less than in some other states. Minnesota census data was released March 16, 2011 and can be accessed at Minnesota's State Demographic Center. The U.S. Census Bureau has a wealth of information related to Congressional Apportionment.


Every member of the U.S. House of Representatives represents a specific area, or district, of their state. Each of these 435 districts has to be changed after each apportionment to reflect changes in the number of congressional seats and/or changes in population demographics in each state. This process is known as redistricting. State legislatures are responsible for creating new congressional districts.

Separate from congressional redistricting is state legislative redistricting. State legislatures are responsible for creating new state legislative districts. Currently in Minnesota, districts are redrawn after each U.S. Census. The number of districts remains the same but district borders are changed to make sure each district has approximately the same number of people in it. In Minnesota, there are 67 state senate districts; each senate district is divided into 2 house districts (134 state house districts), for a total of 201 state legislative districts.

Minnesota's nonpartisan Legislative Coordinating Commission is responsible for assisting the legislature in carrying out its redistricting responsibilities under Minnesota Statutes, section 2.91. In early 2011, the Minnesota Legislature received U.S. Census data for Minnesota and the process of creating congressional and state legislative districts began. The Minnesota Legislature's Geographic Information Services Office has posted a Redistricting Timetable for 2010-2012 as part of their Redistricting 2010 website.

Drawing congressional and legislative district boundaries is a difficult political process. Ideally, staff hired by the four legislative caucuses (House Republican Caucus, House DFL Caucus, Senate Republican Caucus, and the Senate DFL Caucus) draft proposed redistricting plans and come to consensus on plans that meet the technical requirements of law. The plans are then presented to the legislature as a bill that must be passed by the legislature and approved and signed by the governor (2010 Redistricting Plans). New congressional and legislative districts must be determined early enough to give sufficient time to prepare for the state primary election on August 14, 2012. The statutory deadline is twenty-five weeks before the primary election. (Minnesota Statutes, section 204B.14, subdivision 1a).

Role of the Courts

The redistricting plan can end up in the courts if the legislature and governor fail to agree on a plan or if someone files a lawsuit against the approved plan. Minnesota's congressional and legislative plans have often been referred to the courts. (See: History of Minnesota Redistricting; Resources on Minnesota Issues: Redistricting 1990; Resources on Minnesota Issues: Redistricting 2000.)

A lawsuit was filed Wednesday, January 12, 2011 in U.S. District Court as Audrey Britton, et al. v. Mark Ritchie, Secretary of State of Minnesota, et al. over the state's redistricting process. The suit asked for an order to intervene in the redistricting process, alleging that the current district boundaries discriminate against high-population districts and that the Legislature can't be expected to produce a better result this year.

Minnesota Supreme Court Chief Justice Lorie Gildea appointed five judges to a special redistricting panel on June 1, 2011. The judicial panel would hear challenges to the state's redistricting process and in the event that the MN Legislature and Governor Dayton failed to agree on a plan by February 21 of 2012, the panel would then draw the lines itself. The panel issued a scheduling order on Thursday, October 6, 2011 instructing all parties to have their proposed maps to the court by November 18, 2011. The court had a hearing on the plans on Jan. 4, 2012. At 1 p.m. on Tuesday, February 21, 2012, without a final agreement between the Legislature and Governor, the five-judge panel released the state's new redistricting maps. The 2012 maps are posted on the Legislative Coordinating Commission's Geospatial Information, Redistricting Plan L2012 website.

Local Redistricting

Once districts are established, local units of government with districts apportioned by population must also redistrict themselves. When all the districts have been determined, boundaries for election precincts are set.
