Case Study: Marion County, IN — Modernizing the Voting Experience

December 12, 2019

One of the largest counties in the U.S. moves to a secure, modern, all-access opportunity to vote.


Across the U.S., pioneering election officials are advancing elections by replacing aging voting systems with innovative paper-based voting technology. Marion County, Indiana, adopted systems that have proven successful in hundreds of elections to implement a new approach to the traditional neighborhood-based polling location.

Marion County, home to the city of Indianapolis, is meeting the needs of their more than 600,000 voters though a voter-centric approach to elections.

In 2019, the county introduced ES&S’ ballot marking device for all voters with the latest in security technology and a physical paper ballot for tabulation.

In addition, the county made voting more convenient for the voter by moving from traditional neighborhood-based polling locations to vote centers allowing voters to cast their ballots at any one of the nearly 300 vote centers across the county.


Vote centers require efficient, predictable processes and more engaged management. Marion County required a voting system that could:

  • Handle 1,400 digital ballot styles while providing an auditable paper trail
  • Ensure every ballot style was available at every vote center without the complications of pre-printing traditional paper ballots
  • Support nearly 300 vote centers

Marion County also sought to:

  • Provide ALL voters with the same easy, secure voting experience
  • Allow voters the opportunity to verify their selections before casting a paper ballot
  • Ensure the ability to perform a statistically valid, post-election audit of election results
  • Replace aging voting equipment reaching the end of its lifespan
  • Handle the testing of many machines in a short timeframe
