Midterm voting rate compared to total voting-age population

This rate is the number of people who voted in each US midterm election divided by the number of people aged 18 or older at the time of the election. Since there are members of the voting-age population who cannot vote, such as non-naturalized immigrants and felons in some states, this voting rate will never reach 100%.

In 2018, the midterm voting rate compared to total voting-age population was 49%, an increase of 10.5 percentage points from the preceding midterm election cycle in 2014.
