There were no statewide elections held in Indiana in 2021, but rest assured, those involved in our election processes are hard at work in collecting and analyzing data to be ready for the next cycle.

Election data is a lot more than just the final vote tallies. In the video for lesson 8, you’ll learn about the history of polling and polling data, plus how political polls monitor public opinion over time. Polls are conducted by independent research groups and news organizations or by firms hired by campaigns themselves.


In the extra reading for Lesson 8, check out the article How Political Campaigns Use Your Data from Reuters just prior to the November 2020 election. The article explains concepts you may or may not be familiar with like the U.S. “voter file”, layering data, predictive models and data-informed campaigns. The article describes how “campaigns use data to inform decisions and create voter files about everything from where to send mailers, which places candidates should visit and where to buy or target TV ads (Reuters).”
