Is there, as the media likes to suggest, really such a large income gap between Hillary Clinton and Bernie Sanders enthusiasts? Who are the people throwing their support behind these two candidates?

Political data and crowdfunding site Crowdpac combed the zip codes across the United States to determine the places where either candidate has most out-performed the other in fundraising—in other words, the most pro-Clinton or pro-Sanders parts of America. Their findings reveal some pretty stark differences in the two groups of supporters' income levels.

As the graphics below show, the average household income for those in the most pro-Clinton zip codes—places like Beverly Hills; Manhattan's Upper East Side; and Washington, D.C.—is $448,000. Majority pro-Sanders zip codes, by comparison, have an average household income of $103,000 a year.

The median household income in the U.S. as a whole is just $53,046, according to the Census Bureau, so that's not to say the pro-Sanders zip codes aren't relatively wealthy areas. It's just that some of these Clinton-heavy areas approach elite, one percent-like wealth.

Sanders' backers may be financially comfortable; Clinton's are much more so.
