I need to measure average income within buffers that I traced around polluting plants. The income data comes from a polygon file with census-tract level income. I have tried to use the intersect tool (the plan was to use the statistics tool after, once I had linked each buffer to all the intersecting census-tract), but it does not work. I think the problem is that the buffers can overlap with each other. Is there any solution that you could suggest? Thanks!
