re: ‘Duck Dynasty’ vs. ‘Modern Family’: 50 Maps of the U.S. Cultural Divide

What was the methodology for determining this? When I first read this I thought "Nielsen ratings" but their list doesn't even come close to comparing to Nielsen's (ex: Sunday and Thursday Night Football were numbers 1 & 3 with Big Bang being #2).


Also, rural Alaska is about as rural as it gets with vast stretches of complete wilderness. Having some level of colorization there strikes me as misleading.
