These files represent the boundaries of the post-2010 census state legislative and 113th Congressional district plans as collected by the U.S. Census Bureau in Phase 4 of the Redistricting Data Program (RDP). These plans are those understood to be in effect for the November 2012 elections as of their production date. The plans were submitted to the Census Bureau by non-partisan state liaisons, identified by the governor and legislative leadership of each state during Phase 1 of the RDP. Once these plans were processed and inserted into the MAF/TIGER database, the Census Bureau generated verification materials for each state to review and certify as accurate. Any reported changes to the verification materials were incorporated into these final products.
The 113th Congressional District Summary File contains the data compiled from the questions asked of all people and about every housing unit in the 2010 Census. Population items include sex, age, race, Hispanic or Latino origin, household relationship, household type, household size, family type, family size, and group quarters. Housing items include occupancy status, vacancy status, and tenure (whether a housing unit is owner-occupied or renter-occupied). The file contains subject content identical to that shown in the 2010 Census Summary File 1. This data is also available through the American FactFinder Tool
The 2012 State Legislative District data is now available from the 2012 ACS 5-year estimates. Data is provided for whole legislative districts for the full compliment of ACS tables. This data is available through the American FactFinder Tool by selecting the 2012 ACS 5-year estimates as your dataset. This data can also be pulled from the 2012 ACS 5-year estimates summary files available via FTP.
The Congressional District Relationship files provide simple relationships between the Congressional Districts and other Census tabulation geography including American Indian areas, counties, county subdivisions, census tracts, places, school districts, urban/rural population and land area, and ZIP Code Tabulation Areas.
The 2012 State Legislative District Relationship files provide simple relationships between the Legislative Districts and other Census tabulation geography including American Indian areas, counties, county subdivisions, census tracts, places, school districts, urban/rural population and land area, and ZIP Code Tabulation Areas.
These shapefiles are being released as official TIGER/Line Shapefile products. This version of the TIGER/Line Shapefiles include the 113th Congressional District boundaries by state and as a national file, the State Legislative Districts (2012 election cycle), and the supporting 2010 Census geography. The congressional and state legislative district boundaries are the official boundaries as represented by the state liaisons, in Phase 4 of the Redistricting Data Program, including any split 2010 census tabulation blocks.
The files for the 113th Congressional and 2012 State Legislative Districts are identified by their abbreviation within the file name.
These BEFs are the whole 2010 census tabulation block representations of the plans as submitted to the U.S. Census Bureau. In instances where plans included split blocks, it was requested that the state liaison identify a single district to assign the split block for use by the U.S. Census Bureau for data tabulation purposes. The fields in these files should be imported as text to preserve leading zeros.
Where the boundary of a Congressional District or a state legislative district splits a 2010 Census block, the Census Bureau's maps and TIGER/Line files depict its location correctly, but for data tabulation purposes, that block is allocated in its entirety to the Congressional District or state legislative district specified by the state.
The Easy Stats data tool has added some 2012 American Community Survey 1-Year estimates for the new 113th Congressional Districts.
