The electorate in this year’s elections will be the most diverse and well-educated electorate in the history of the United States. Nationwide, non-Hispanic whites without a college degree were a slight majority of all voters in 2010 (51.0%), but by 2018 had fallen to just 44.6% of all voters. At the same time, Hispanic, Asian American, and Black/African American voting blocs have all increased. All told, the number of non-Hispanic white voters without a college degree shrank by almost 5.5 million between 2010 and 2018, while the number of non-white voters increased by more than 15.3 million and the number of non-Hispanic white voters with a college degree increased by almost 8.5 million. This change occurred all across the country. Every single state saw the share of non-Hispanic whites overall shrink between 2000 and 2018, our data also shows that non-Hispanic whites without a college degree also shrank as a share of every state’s electorate as well between 2010 and 2018.
