More than half of U.S. eligible voters cast a ballot in 2018, the highest turnout rate for a midterm election in recent history, according to a Pew Research Center analysis of newly released data from the U.S. Census Bureau. The increased turnout was particularly pronounced among Hispanics and Asians, making last year’s midterm voters the most racially and ethnically diverse ever.
With enthusiasm at a record high, more than 122 million people voted in the 2018 elections, the highest in a midterm election year since 1978. Last year also marked the first time since 1982 that the voter turnout rate in midterm elections surpassed 50%. This was a stark reversal from the previous midterm year, when turnout had decreased – from 45.5% in 2010 to 41.9% in 2014. (The voter turnout rate is the share who cast a ballot among eligible voters, defined as U.S. citizens ages 18 and older. Historical data in this analysis starts in 1978, the first year the Census Bureau gathered citizenship data for its survey of voters.)
