How are NY, NJ and PA counted? Mid Atlantic? If so, that biases the graphic breakdown toward mid-Atlantic.

Only because Phish's shows are biased in that direction. It wouldn't make sense to define Census regions by where Phish plays. If you "unbiased" the regions to make them have comparable numbers of shows, you'd be ignoring the actualities of both geography *and* Phish's performance history instead of looking at their interconnection. The empirical reality is that Phish's tours *are* biased - towards the Mid-Atlantic (and Pacific) and away from their home turf of New England.
