Improving the Accuracy of Ballot Assignment

GeoElections is geography driven. Using GeoAuthor, Census GIS data along with sources from state and local GIS authorities, can be used to improve the integrity of place. The place a voter resides, which in turn dictates the races and issues for which a voter is entitled to cast a vote.

“Some estimate that 10% to 12% of voters in the nation are assigned to the wrong precincts…” 1While all of these voters may not receive ballots that change an outcome in error, how many do receive a ballot that changes an outcome in error? Why should anybody receive a wrong ballot introducing error in the outcome of any election?

Would you accept a loss of 10% of the assets in your retirement account? Inflation and opportunity loss may be unavoidable, but mismanagement is unacceptable. Why would an elections official risk distributing wrong ballots to voters when tools are available to conduct the process with the integrity our continuance expect.


GeoElections can programmatically update the VR street index with the accurate GIS data.

“In close races, every aspect of election procedures will likely be scrutinized, including the assignment of voters.”2

“The state voter registration database has two-thirds of the adult population, so this is your citizen management system,” says Richard Leadbeater of Esri. “This is the start of everything.” The errors, he says, are usually manual: It’s hard to input data accurately. And it’s not possible to do quality control if there is no Geographic Information Systems (GIS) system to compare the data to. So, just the update and correctness of the voter registration files is a huge benefit of moving to GIS-based elections, says Leadbeater. That means using GIS technology in local election offices.”3


GeoElections provides a complete range of tools for the creation of the highest integrity data. With the base map created including precincts and splits, the user can geocode their voters with the GeoElections GeoCoder.

GeoElections has the query capabilities to test the validity of the precinct and/or precinct group assigned to a voter against the values in the base map returning a file of voters out of district. With this information the user can make adjustments to the base map or corrections to the voter registration street index.

When A Map Is

Worth a 1,000 Words

Recently an individual seeking placement on a primary ballot to run for a Congressional District in Florida, conducted a petition drive to avoid the Partisan filling fee of $10,440.00. The goal of the petition was Congressional District 22. According to the “2020 Candidate Petition Handbook”, 4,906 signatures are required to qualify as a candidate as a Representative in Congress for District 22. Amongst other conditions to qualify, voters’ signing the petition must reside within the district the petitioner is seeking. Below is a map of Congressional Districts, Census blocks and voters.


A legend for the elements in the map follows:

    Congressional District 20 – Yellow Congressional District 22 – Blue Congressional District 23 – Magenta Congressional District 24 – Orange 138 Signers as red stars did not qualify The area highlighted in white is a county

Congressional District 22 spans two counties and this study only illustrates the southern portion of 22. This petition failed by a thin margin and the map clearly illustrates the reason for the failure. This map is worth a thousand words and the SOE in this county was diligent in performing their duties.
