I would like to create circles around a point density layer that reflect the magnitude of the point density. I have created a point density estimation for a few towns. Each town varies in population, although the area does not change among them. I would like to create an "area of influence" around in town that reflects the population density. (Larger circles around higher populated towns.)

Is there a way to do this? I am using ArcGIS 10.1

    Are you using the Spatial Analyst tool Point Density? Did you make use of the population_field parameter? I'm not entirely clear on what you're trying to show, and wondering if Kernel Density or even an Interpolation rather than a point density would be better suited. – Chris W Jul 9 '14 at 1:21

If I understand what you are trying to do, you could use the contour tool from ArcGIS spatial analyst. This will create isolines based on your point density map, where you can define a threshold for a given value of your point density.
