    Description

    This map shows Congressional District boundaries for the United States. The map is set to middle Georgia.

    Congressional districts are the 435 areas from which members are elected to the U.S. House of Representatives. After the apportionment of congressional seats among the states, which is based on decennial census population counts, each state with multiple seats is responsible for establishing congressional districts for the purpose of electing representatives. Each congressional district is to be as equal in population to all other congressional districts in a state as practicable. The boundaries and numbers shown for the congressional districts are those specified in the state laws or court orders establishing the districts within each state.

    Congressional districts for the 108th through 112th sessions were established by the states based on the result of the 2000 Census. Congressional districts for the 113th through 115th sessions were established by the states based on the result of the 2010 Census. Boundaries are effective until January of odd number years (for example, January 2015, January 2017, etc.), unless a state initiative or court ordered redistricting requires a change. All states established new congressional districts in 2011-2012, with the exception of the seven single member states (Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming).

    For the states that have more than one representative, the Census Bureau requested a copy of the state laws or applicable court order(s) for each state from each secretary of state and each 2010 Redistricting Data Program state liaison requesting a copy of the state laws and/or applicable court order(s) for each state. Additionally, the states were asked to furnish their newly established congressional district boundaries and numbers by means of geographic equivalency files. States submitted equivalency files since most redistricting was based on whole census blocks. Kentucky was the only state where congressional district boundaries split some of the 2010 Census tabulation blocks. For further information on these blocks, please see the user-note at the bottom of the tables for this state.

    The Census Bureau entered this information into its geographic database and produced tabulation block equivalency files that depicted the newly defined congressional district boundaries. Each state liaison was furnished with their file and requested to review, submit corrections, and certify the accuracy of the boundaries.

    Description

    The National Center for Education Statistics’ (NCES) Education Demographic and Geographic Estimates (EDGE) program develops annually updated school district boundary composite files that include public elementary, secondary, and unified school district boundaries clipped to the U.S. shoreline. School districts are special-purpose governments and administrative units designed by state and local officials to organize and provide public education for local residents. District boundaries are collected for NCES by the U.S. Census Bureau to support educational research and program administration, and the boundaries are essential for constructing district-level estimates of the number of children in poverty.The Census Bureau’s School District Review Program (SDRP) (https://www.census.gov/programs-surveys/sdrp.html) obtains the boundaries, names, and grade ranges from state officials, and integrates these updates into Census TIGER. Census TIGER boundaries include legal maritime buffers for coastal areas by default, but the NCES composite file removes these buffers to facilitate broader use and cleaner cartographic representation. The inputs for this data layer were developed from Census TIGER/Line 2024 and represent boundaries reported for the 2023-2024 school year. For more information about NCES school district boundary data, see: https://nces.ed.gov/programs/edge/Geographic/DistrictBoundaries.Collections are available for the following years:SY 2022-23 TL 23SY 2021-22 TL 22SY 2020-21 TL 21SY 2019-20 TL 20SY 2018-19 TL 19SY 2017-18 TL 18SY 2015-16 TL 17SY 2015-16 TL 16SY 2013-14 TL 15SY 2013-14 TL 14All information contained in this file is in the public domain.

    Description

    This file represents a statewide compilation of the boundaries of all independent, common, and special school districts in the state of Minnesota. Minnesota school districts are asked to report any changes to their district boundaries annually. With the exception of consolidations, dissolutions, or other financial cooperation agreements, the reporting is not mandatory. As independent special purpose government organizations, school districts determine their own district & attendance boundaries, working with neighboring districts and county auditors to ensure proper taxation. The Minnesota Department of Education (MDE) plays no role in determining the actual boundaries.

    Since 2008, district boundaries have also been reviewed against the school district coding provided in county parcels, where it exists. (Parcel data are supplied by counties to MnGeo, who in turn share that with MDE.) The results are overall increased accuracy, but also increased complexity. Conversations with county GIS coordinators and auditors are ongoing with respect to the complex situations reflected within county parcel data, and whether or not these are accurate representations of school district boundaries. Since school year 2021, many "islands" or other unusual situations have been eliminated or simplified as a result of those conversations.

    This file is not intended to represent the "true" boundaries with respect to taxation, but as generalized boundaries focused on ensuring accurate representation in residential areas. As a result, starting in 2021, boundaries have been simplified by removing complex situations in non-residential areas, such as transportation Right-of-Way (ROW), publicly-owned land, tax exempt land, or water. This simplification work is expected to continue each year.

    This data is now also available in CSV format. OBJECTID and Shape columns have been removed from that format.

Description

This map shows Congressional District boundaries for the United States. The map is set to middle Georgia.

Congressional districts are the 435 areas from which members are elected to the U.S. House of Representatives. After the apportionment of congressional seats among the states, which is based on decennial census population counts, each state with multiple seats is responsible for establishing congressional districts for the purpose of electing representatives. Each congressional district is to be as equal in population to all other congressional districts in a state as practicable. The boundaries and numbers shown for the congressional districts are those specified in the state laws or court orders establishing the districts within each state.

Congressional districts for the 108th through 112th sessions were established by the states based on the result of the 2000 Census. Congressional districts for the 113th through 115th sessions were established by the states based on the result of the 2010 Census. Boundaries are effective until January of odd number years (for example, January 2015, January 2017, etc.), unless a state initiative or court ordered redistricting requires a change. All states established new congressional districts in 2011-2012, with the exception of the seven single member states (Alaska, Delaware, Montana, North Dakota, South Dakota, Vermont, and Wyoming).

For the states that have more than one representative, the Census Bureau requested a copy of the state laws or applicable court order(s) for each state from each secretary of state and each 2010 Redistricting Data Program state liaison requesting a copy of the state laws and/or applicable court order(s) for each state. Additionally, the states were asked to furnish their newly established congressional district boundaries and numbers by means of geographic equivalency files. States submitted equivalency files since most redistricting was based on whole census blocks. Kentucky was the only state where congressional district boundaries split some of the 2010 Census tabulation blocks. For further information on these blocks, please see the user-note at the bottom of the tables for this state.

The Census Bureau entered this information into its geographic database and produced tabulation block equivalency files that depicted the newly defined congressional district boundaries. Each state liaison was furnished with their file and requested to review, submit corrections, and certify the accuracy of the boundaries.
