That’s a very interesting chart. It seems to me that the numbers are in some way tied to population density, no? The more crowded a state is, it seems, the less bang for the buck they get.
This shows up even within regions. For example, sparsely populated Maine gets $1.41 while densely populated Massachussetts gets $.75. New Jersey, which barely has any space to walk anymore, gets $.65, while Maryland, which has maintained a pretty fair amount of rural space even given the burgeoning population centers of the D.C. suburbs, gets $1.30.
Is this a reasonable inference?

But I think an even better correlation is the poverty level of a given state:
