TIGER/Line Shapefile, 2015, Series Information for the Current Unified School Districts Shapefile State-based Shapefile

The TIGER/Line shapefiles and related database files (.dbf) are an extract of selected geographic and cartographic information from the
U.S. Census Bureau's Master Address File / Topologically Integrated Geographic Encoding and Referencing (MAF/TIGER) Database (MTDB). The MTDB represents
a seamless national file with no overlaps or gaps between parts, however, each TIGER/Line shapefile is designed to stand alone as an independent data
set, or they can be combined to cover the entire nation.

           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 2013-2014 school year.
