During the 2018 mid-term election, the voter turnout rate for the state of Arizona was 43.7 percent. This was more than six percentage points lower than the rate during the 2016 presidential election. Traditionally, voter turnout is significantly lower during mid-term election years. In Arizona, voter turnout is relatively low when compared to other western states, ranking sixth out of 10 western states. The Tucson Metropolitan Statistical Area (MSA) has exceeded the state’s rate of voter turnout for at least the past eighteen years. In 2018, it was 47.5 percent. Voter turnout is an important measure of civic engagement, and higher turnout rates cause election results to better reflect the will of the people.
