Population of Metro Detroit = 4,500,000
Percentage of general population assumed to be gay = 10%
Percentage of population that is male = 49%
Shave off a fraction for the underage set = 25%
Total guess on percentage of males in metro area with professional careers = 35%
Simple math and some broad assumptions leave me with the following conclusion: there are 57,881 professional gay men over 21 in Metro Detroit.
Does it seem like that many to you? Where the hell are they all?
