Spatial distribution of amenities, by census tracts. (A) The fitted exponential distribution of restaurants (by census tract). The steeper the rate of decay (Charlotte), the more unevenly restaurants are distributed. Lower rates of decay (San Francisco) mean a more even distribution of restaurants. A comparison of the fitted and actual distributions are provided in Additional file 1, Figure S1. (B) The exponential rate of decay for population density (x-axis) and the exponential rate of decay for amenity density in a city (y-axis) show a good fit on a double logarithmic scale (\(R^{2}=0.73\)). (C) The same is true for a single amenity type such as ATMs (\(R^{2}=0.82\))
