Trump voters’ median income exceeded the overall statewide median in all 23 states, sometimes narrowly (as in New Hampshire or Missouri) but sometimes substantially. In Florida, for instance, the median household income for Trump voters was about $70,000, compared with $48,000 for the state as a whole. The differences are usually larger in states with substantial non-white populations, as black and Hispanic voters are overwhelmingly Democratic and tend to have lower incomes. In South Carolina, for example, the median Trump supporter had a household income of $72,000, while the median for Clinton supporters was $39,000…

Many of the differences reflect that Republican voters are wealthier overall than Democratic ones, and also that wealthier Americans are more likely to turn out to vote, especially in the primaries. However, while Republican turnout has considerably increased overall from four years ago, there’s no sign of a particularly heavy turnout among “working-class” or lower-income Republicans. On average in states where exit polls were conducted both this year and in the Republican campaign four years ago, 29 percent of GOP voters have had household incomes below $50,000 this year, compared with 31 percent in 2012…

Class in America is a complicated concept, and it may be that Trump supporters see themselves as having been left behind in other respects. Since almost all of Trump’s voters so far in the primaries have been non-Hispanic whites, we can ask whether they make lower incomes than other white Americans, for instance. The answer is “no.” The median household income for non-Hispanic whites is about $62,000,4 still a fair bit lower than the $72,000 median for Trump voters.
