Redistricting data

Census 2020

The Census Bureau has released the redistricting data in a format that is difficult for most users to work with. Many government agencies use census data for funding and planning purposes.

There are several resources available for accessing the 2020 Census redistricting data. They are:

State Demographic Center Data

Our office has reformatted the most-requested data into easy-to-use CSV files, so that the legislature and others in Minnesota can use the data for redistricting work. The census blocks from the redistricting file have been added together to obtain the total population of townships, cities, counties, and tribal areas. For some geographies we have included an additional codebook and data file with 2010 and 2020 data.

  • Census Blocks - Statistical areas bounded not by population but by visible features such as roads, streams, and railroad tracks, and by non-visible boundaries such as property lines, city, township, school district, county limits and short line-of-sight extensions of roads. These boundaries change frequently and are the smallest level of geography you can get basic demographic data for, such as total population by age, sex, and race.

  • Census Block Groups - Statistical divisions of census tracts, are generally defined to contain between 600 and 3,000 people, and are used to present data and control block numbering. A block group consists of clusters of blocks within the same census tract that have the same first digit of their four-digit census block number.

  • Census Tracts - Small, relatively permanent statistical subdivisions of a county or equivalent entity that are updated by local participants prior to each decennial census. Census tract boundaries are delineated with the intention of being maintained over a long time so that statistical comparisons can be made from census to census.

  • Places - An incorporated place usually is a city, town, village, or borough, but can have other legal descriptions.

  • County Subdivisions - The primary divisions of counties and equivalent entities. They include census county divisions, census subareas, minor civil divisions, and unorganized territories and can be classified as either legal or statistical.
  • County Subdivisions codebook --> 2020

  • Counties - The primary legal divisions of most states are termed counties. Minnesota has 87 counties.

  • State Legislative Districts - State legislative districts (SLD) are areas from which members are elected to state or equivalent entity legislatures. State legislative districts embody the upper (senate—SLDU) and lower (house—SLDL) chambers of the state legislatures.
  • State Legislative Districts Lower (House) codebooks --> 2020 | 2010 and 2020

  • Congressional Districts - Congressional districts are divisions of a larger administrative region that represent the population of a region in the larger congressional body.
