NYU PhD candidate Sean Taylor had an internship at Facebook Data Science, and he used that time to break down NFL fan bases based on geography and only using data from Facebook.
According to the Daily Mail:
Sean Taylor has published a series of new maps based on Facebook figures that show a surprising social and geographical breakdown of NFL fans.
About 35 million people on Facebook have 'liked' one of the 32 NFL teams, or roughly one out of every ten Americans. Those numbers now show a divided country loaded with random fan clusters and holdouts.
'Technically this was all quite trivial, mostly just aggregating users by teams and geography,' he explains on his blog. 'If I had had more time, I would have looked for rivalries. The idea was to look for some pairs of teams that despite having pairs of fans in close proximity are unlikely to have fan friendships.'
He added that teams like the Steelers, Cowboys, and Packers 'transcend geography, with pockets of fans all over the country. On the other end of the spectrum, the Jets have to share New York with the Giants and are only the most popular team for a single stronghold county in Long Island.
In a less-than shocking discovery, the table below shows how society is a bunch of bandwagon-jumping front-runners (not everyone...not everyone). According to Taylor's findings and based on "Likes" teams pages received throughout the year, teams gain the most fans when they win playoff games.
And then here is the map of how the country is rooting in this week's Super Bowl
