The UF Election Lab

The Election Lab at the University of Florida is a collaboration of faculty and students who study voting and elections through analyses of survey and election data. Our mission is to provide timely and accurate statistics, software, reports, and other useful information, primarily regarding voting and elections in the United States.

Our goals are to better inform people about how elections work, how voting may be improved, and how the public can become more engaged and more confident in the electoral process.

2020 Precinct Election Results


  • New research by UF Election Lab undergraduate students and faculty published in American Politics Research investigates the effect of campus evacuation orders on student voting during the 2020 presidential primary early voting period.
  • The Voting and Election Science Team released 2016, 2018, and 2020 updates for Michigan, Nevada, Washington, and Wisconsin. The Nevada and Washington update small precinct boundary errors we uncovered during our 2022 work. Michigan’s update is to correct geographic identifiers and a 2018 issue for Kalamazoo’s election results. Wisconsin updates are more substantive, in that they change the methodology of apportioning election results locality-wide to wards for some localities where we do not have ward-level data. Formerly we apportioned data according to the voting-age population. In this update we apportion data according to voter registration.
  • The Voting and Election Science Team has released 2022 data for Arizona, Delaware, Florida, Hawaii, Kansas, Maryland, Massachusetts, Michigan, Minnesota, North Carolina, Nevada, Rhode Island, South Carolina, Utah, Vermont, Washington, and Wisconsin. These data are available to subscribers. Contact for subscription information. (Bold denotes recent releases.)
  • Professor McDonald is tracking turnout in the 2024 presidential nomination contests.
