EDS offers political information products for businesses, associations, and governmental organizations. Election Data Services has applied 39 years of experience with redistricting, elections, and GIS (geographic information systems) towards the development of a variety of political information products for businesses, associations, and governmental organizations. Current products include election returns and voting statistics, district boundary files, a ZIP+DISTRICT file linking postal ZIP Codes to district boundaries, data on voting equipment usage, contact information for state and local election officials, and an election poster with maps showing the results of November general elections for President, U.S. Senator, and U.S. Representative, governorships and state legislatures. Election Data Services has also developed GIS software — PRECIS Precinct Information System — for election officials to manage voting precincts and assign voters to precincts and districts.
Data files linking ZIP Codes to congressional and legislative districts
ZIP+DISTRICT is a database that links five and nine-digit USPS (United States Postal Service) ZIP Codes to 435 congressional districts and some 6,000 legislative districts, including districts for the upper and lower houses of 49 state legislatures, Nebraska’s unicameral legislature, and Council of the District of Columbia.
District Boundary Files
Boundaries of current congressional and legislative districts
Election Data Services maintains a nationwide database of district boundaries and offers congressional and legislative district boundary files for geographic information systems (GIS). The database includes representative districts for the United States Congress as well as districts for the upper and lower houses of 49 state legislatures, Nebraska’s unicameral legislature, and the Council of the District of Columbia.
Election Data Files
County-level election returns and voter participation statistics
Election Data Files contain county-level tabulations of election results and voter participation statistics from November general elections in the United States. The tabulations of election results are for the following federal and statewide contests: (1) president of the United States, (2) U.S. Senator, (3) U.S. Representative, and (4) governor. Voter participation statistics include (1) estimated voting age population (VAP), (2) voter registration, and (3) voter turnout.
Election Administration Data Files
Profiles of some 8,000 election jurisdictions in the United States
Since 1980 Election Data Services has maintained a database on election administration that profiles more than 8,000 election jurisdictions in the United States, including 3,000 counties and county equivalents, and 4,900 townships in Michigan, Wisconsin, and the six New England states—Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island, and Vermont.
The Election Administration Data Files include for those jurisdictions population (e.g., voting age population, or VAP) data, voter registration data, numbers of voting precincts, contact information for election officials, and data on voting equipment in use.
A comprehensive, easy-to-use precinct management solution for ArcGIS (ESRI)
PRECIS® is geographic information system (GIS) that Election Data Services developed to provide election administrators with a comprehensive, easy-to-use solution for managing voting precincts and assigning voters to precincts and districts. PRECIS uses an enhanced Census TIGER base map and data from a jurisdiction’s Registered Voter File to pinpoint voters on a digital map. This allows users to see where voters reside and to monitor dynamically-updated voter counts as they use the PRECIS mapping tools to draw new precincts or to split, consolidate, or adjust the boundaries of existing precincts. A simple click of a button generates a Street Index File that can be exported to a voter registration system to update voter assignments to precincts and districts.
