Boca Juniors Supporters

Boca Juniors is traditionally regarded as the club of Argentina's working class, in contrast with the supposedly more upper-class base of cross-town archrival Club Atlético River Plate.

Boca Juniors claims to be the club of "half plus one" (la mitad mas uno) of Argentina's population, but a 2006 survey placed its followers at 40%, still the largest share. They have the highest number of fans, according to their percentage in their country.

The Boca-River Superclásico rivalry is one of the most thrilling in the world. There were 327 matches; Boca have won 121, River 105 and there have been 101 draws. After each match (except ties), street signs cover Buenos Aires, at fans' own expense, "ribbing" the losing side with humorous posters. This has become part of Buenos Aires culture ever since a Boca winning streak in the 1990's.
