 Geocoding 1.5 Million Registered Voters in Maricopa County, Arizona Track: State and Local Government Author(s): Tim Johnson This paper presents the results of a GIS project undertaken by the Maricopa County Recorder/Elections Department to accurately geocode all of the registered voters in the County. The purpose of the project was to locate each voter's address with a high degree of certainty and repeatability. The geocoded data is used for population and district analysis within the department and as part of a larger plan to employ GIS technology in real time voter district assignments. All together, there are over 1.5 million voters to geocode. Meeting a goal of a 100 percent match rate required a variety of data sources, data manipulation, and geocoding techniques.
