NY's population is 8.6 million people. Boston has a population of 685,000. NY outnumbers Boston by 8 million people. what is the "fan base" though? New York is split between 2 teams and has Philly fans to the south/southwest, Boston has all of New England? Not sure. But the first list suggests they capture a large audience beyond the city as they are #7 market in the US. But it's hard to imagine any surrounding area making up the difference in population. NYC has 8.6 million people. Let's be conservative and allocate 70% of that market to the MFY. That still leaves 2.58 million for the Mets. And that's not counting LI, NJ, upstate NY and parts of CT. the entire population of new england (minus connecticut) (~9M) is slightly more than the population of the 5 boroughs of new york city (~8.6M). lets do some math. for the purposes of this exercise, let's consider all of new york state to be fans of either the yankees or the mets. we'll add in 1/2 of connecticut, and 2/3 of jersey. which is unfair because jersey is too good of a state too have so many of us fall sway to the phillies. but whatever - it's an approximation, and i'm trying to be overly conservative... new york has 19M people. CT has 3.5M and NJ has 7M. of that, we allocate 1.75M and 4.7M respectively to the NY market. total available fanbase of 25.4M. applying the 70/30 split above, the mets should have about 7.6M to draw from. it's a bit shy of the 10.75 i'm allocating to boston, and far short of the 17.8M i'm giving the yankees. but it still a big enough number that the mets should be pretty big players in the payroll games. also, it goes without saying that as the mets fortunes improve, their share of the new york market can grow as well. in other words. spend spend spend.
