  • Current Secondary School Districts Shapefile

    School Districts are single-purpose administrative units within which local officials provide public educational services for the area's residents. The Census Bureau obtains the boundaries, names, local education agency codes, grade ranges, and school district levels for school districts from State officials for the primary purpose of providing the U.S. Department of Education with estimates of the number of children in poverty within each school district. This information serves as the basis for the Department of Education to determine the annual allocation of Title I funding to States and school districts. TIGER/Line Shapefiles include separate shapefiles for elementary, secondary and unified school districts. The school district boundaries are those in effect for the 2011-2012 school year.

  • 2019_addrfeat

    The Address Ranges Feature Shapefile (ADDRFEAT.dbf) contains the geospatial edge geometry and attributes of all unsuppressed address ranges for a county or county equivalent area. The term "address range" refers to the collection of all possible structure numbers from the first structure number to the last structure number and all numbers of a specified parity in between along an edge side relative to the direction in which the edge is coded. Single-address address ranges have been suppressed to maintain the confidentiality of the addresses they describe. Multiple coincident address range feature edge records are represented in the shapefile if more than one left or right address ranges are associated to the edge. The ADDRFEAT shapefile contains a record for each address range to street name combination. Address range associated to more than one street name are also represented by multiple coincident address range feature edge records. Note that the ADDRFEAT shapefile includes all unsuppressed address ranges compared to the All Lines Shapefile (EDGES.shp) which only includes the most inclusive address range associated with each side of a street edge. The TIGER/Line shapefile contain potential address ranges, not individual addresses. The address ranges in the TIGER/Line Files are potential ranges that include the full range of possible structure numbers even though the actual structures may not exist.

  • Current State Legislative District (SLD) Upper Chamber

    State Legislative Districts (SLDs) are the areas from which members are elected to State legislatures. The SLDs embody the upper (senate) and lower (house) chambers of the State legislature. Nebraska has a unicameral legislature and the District of Columbia has a single council, both of which the Census Bureau treats as upper-chamber legislative areas for the purpose of data presentation; there are no data by SLDL for either Nebraska or the District of Columbia. A unique three-character census code, identified by State participants, is assigned to each SLD within a state. In Connecticut, Illinois, Louisiana, Maine, Maryland, Massachusetts, Michigan, Ohio, and Puerto Rico, the Redistricting Data Program (RDP) participant did not define the SLDs to cover all of the state or state equivalent area. In these areas with no SLDs defined, the code "ZZZ" has been assigned, which is treated as a single SLD for purposes of data presentation. The boundaries of the 2012 State legislative districts were provided by State-level participants through the RDP and reflect the districts used to elect members in or prior to the November 2012 election.

  • Census Bureau Planned Acquisition

    The Census Bureau updates and maintains address data to support the correct allocation of population and housing for censuses and surveys. Boundaries, streets, addresses, structure points, and selected other features are maintained in the Master Address File/Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) database. The Census Bureau collects geographic and address data from tribal, state, and local governments through a Geographic Support System Initiative (GSS-I) Partnership Program and through other geographic programs, such as the annual Boundary and Annexation Survey. When the Census Bureau updates the MAF/TIGER database with new or corrected street, address and structure point data, the boundary network must be updated concurrently to preserve geographic relationships. Additional sources of data are required to ensure complete coverage of all street centerlines and addresses for the fifty States, the District of Columbia, Puerto Rico, and the Island Areas. Some government partners are unable to provide street and address data that meets the Census Bureau's requirements. Therefore, the Census Bureau is requesting proposals for provision of address data from commercial vendors that can be easily integrated into the MAF/TIGER database.
