July 9, 2014: updated for the 2014 FIFA World Cup in Brazil. This series of interactive maps shows the Elo ranking and Elo rating for all countries in the world. The Elo ranking is an alternative to the official FIFA ranking for ranking men"s national football (soccer) teams in the world. Although not as well-known as the FIFA world rankings, it is sometimes considered more accurate because it takes into account ALL international "A" matches, not just FIFA-recognized international matches. It also uses a slightly different calculation (e.g. taking into account goal difference). Originally invented as a chess rating system, Elo rankings are now used for many different sports.
