OK, Game of Thrones nerds, we know: there is no official population number for Westeros. The books, which thoroughly inhabit their medieval world, tell us that no census has been taken, though you can sort of figure it out from the sizes of cities. "The population of Westeros extends into many millions:" that's the best estimate over at the Game of Thrones wiki.

Well, the size of its fan base on social media has now also been estimated in the millions — only it's a little more census-like. There are 5,493,248 of you nerds, according to Facebook likes and Twitter followings gathered by analytics firm SocialBakers.

And your numbers are growing faster than fireballs at Blackwater Bay. Growth is at a rate of up to 32,000 new fans a day. That's about the size of the army of the North in the show (right nerds?) being added to its fan base every 24 hours.

If this fandom was a house in Westeros, its words would match those of the show's Lannisters: Hear Me Roar.

We're starting to listen.

Who Loves Thrones Best After the U.S.?

Here's what's really interesting: only a third of the fans are in the U.S. The second largest nationwide following belongs to — wait for it — Brazil. Westeros is reputedly the size of Latin America, as every nerd knows, so a following south of the Equator makes a certain kind of poetic justice.

The character in the show most frequently mentioned on Twitter: Jon Snow. Perhaps because it's so much fun to say, "You know nothing, Jon Snow"?

For more fascinating tidbits, here's more from SocialBakers. Don't forget to let us know in the comments your meticulously-calculated guesses for the size of Westeros.
