Interestingly, at least for the cities in the southeast where I've lived, these maps are amazingly good proxies for gentrification. For example, have a look at Houston, TX or Memphis, TN.
In the Midwest, the trend is much less clear. For example, Madison, WI is covered with bikepaths, so there's no clear relationship. (Same for Anchorage, AK. You can see the main trail system, and it pretty much circles the city.)
In a lot of other places, the pattern is controlled by topography/parks (e.g. Birmingham, AL)
I'm limiting things to cities where I've lived, but does anyone else notice similar patterns?
