9.1 million votes: See the demographics of Illinois' voting population

In 2020, 158.4 million citizens—almost two-thirds of estimated eligible voters—voted in the presidential elections, according to the Pew Research Center. The number represented a higher than average turnout, with people voting in numbers not seen since 1980 and possibly well before.

Stacker compiled voter demographics for each state and Washington, D.C., using the 2019 U.S. Census Bureau's American Community Survey (released in September 2020). Each slide shows the state's voting-eligible population (citizens who are 18 or older) and the breakdown of that population by sex, age, race, and education. Economic statistics are not included because the American Community Survey does not account for COVID-19, which affected unemployment, poverty, and medical insurance status for millions of Americans. In order to avoid making any assumptions about the data or the participants of the American Community Survey, Stacker used the exact wording of the "race" and "sex" framework that was provided in the census data.
