The experts have already sized up the World Cup teams, game statistics and rivalries, but what can we learn about the fans?  In preparation for World Cup game watching, Social Explorer gives you a glimpse into populations from all over the globe.

Focusing on the US’s competitors, during last week’s tight game with Slovenia, 175,701 US residents of Slovenian ancestry likely celebrated when the game tied.  (Slovenia has been a nation since 1991, and the Census has data on Slovenians in the US starting in 2000.)

In the final game of the first round, the US will face Algeria, and US fans will share cheers and jeers with the 171,284 US residents of Other Arab ancestry.  (Because few Algerians live in the US, residents with Algerian ancestry are counted together with other smaller Arab populations as “Other Arab” and with “Other Northern Africa” for place of birth.)

Plus, have you ever wondered how many of your neighbors might be carrying a vuvuzela?

A total of 52,209 US residents are of South African ancestry.

You can use Social Explorer’s reporting tools to size up the fan scene for your World Cup team, by ancestry or place of birth, before you head to that World Cup game gathering.  (All data cited above taken from the 2006-08 American Community Survey.)
