Working my figures off memory here:
Boxing's fan base in the US is around 50 million
UFC's fan base as of 2012 is around 22 million
25% of boxing fans are considered young - 12.5 million
80% of UFC fans are considered young - 17 million
In terms of youth culture the UFC seems to be ahead but not really by a whole lot. Like many things those rumours are over blown. It's been part of the UFC's marketing strategy to attract the youth and denounce boxing as your father's sport. It's nothing but propaganda really and isn't supported by ANY factual evidence whatsoever.
The UFC has an unusually high percentage of young fans that I don't think is matched by any other sport. However that's only a percentage of relatively small fan base. They have a large slice of a small cake so to speak.
