A while back, before the Crash, someone posted a link to a website with attendence from various football leagues and clubs of all different codes, i.e. American, Association, Aussie, Canadian, etc. Anybody have that link?
I think www.soccerstats.com has many of those numbers, though I couldn't find an archive. They do it as it goes along. www.football-data.co.uk has some data files from some European leagues that you can import into an excel file and figure attendance (and other things) yourself.
I've been looking for the same site myself as my bookmarks were wiped out. There is no other site comparable so, really, it's pointless to post other sites. Hopefully, someone will remember it.
Another good site is www.worldfootballrankings.com. It has attendance figures for about every league and most every club on the planet that plays "football" (i.e., soccer, American football, rugby, etc,). Unfortunately the figures haven't been updated since last year, but it's still a good resource to get an overall picture of attendance around the world.
DC United is #121 ! DC United is included in the Top125 soccer clubs based on attendance as #121! http://www.worldfootballrankings.com/worldfootball2001/SoccerTop125Clubs.html
