Between fear-mongering documentaries and an ever-increasing number of people convinced they're allergic to gluten, it's tough out there in the burger game, but that hasn't stopped many a burger brand from taking hold of America's hearts, minds, and wallets... mostly hearts, though. But which of America's biggest burger chains are most beloved? And what parts of America love them?
To answer these questions, we crawled over 20,000,000 Foursquare check-ins to see how many people eat what type of burger and where. Then we calculated what brands over-indexed the highest in every county. Then we got really hungry and ate burgers until we passed out. Then we woke up and made this map, which you can look at in even greater detail via this enlarged version.
