RIO DE JANEIRO (AP) — A poll published Sunday on the wealth and race of fans who attended a World Cup match in Brazil illustrated what any TV viewer in the nation has seen: Those attending games are overwhelmingly white and rich.

That’s particularly striking in Brazil, with its highly mixed population that has more blacks than any country with the exception of Nigeria. More than half of Brazil’s population self-identified themselves as black or of mixed-race in the 2010 census.
