Whatever fan survey statistic had the Cubs as the highest cost for a family of four, which was like $375 or something. So a little under $100 per person in revenue. I've seen those types of estimates but I've never been clear on if that is actually representative of the average(e.g. there's one version of this I've seen with borderline excessive food purchases). Similarly, there's some average cost per ticket stuff out there but when I poke around it seems like it mostly is talking about season tickets, which is helpful but not a 1:1 comparison. The one I looked up included 4 hot dogs, 4 soda and 2 beers, which I feel is the least likely purchase by any family of four, but probably a safe low end average. When I was a kid we didn't spend a dime on concessions. Now I can't go to a game without getting a half dozen beers as a starter.
