Let me tell you how that article was compiled.
A bunch of the editors were sitting around one day brainstorming and came up with the idea of making up some lists. The hottest chicks, the best sports towns, the most economical ski vacations, 20 best backpacking trails, etc.
Somebody suggested rating towns by the fitness of their occupants. Now it would be too expensive to send some reporter around to check out 100 towns. So they put somebody in front of a screen and said to come up with some stats on a variety of matters and come up with a list by the next publication date.
And he did.
