I've created buffers around home origins and am looking to calculate the sum of shapefiles (in this case crime) within each buffer. How would I go about doing this? I want to know how many crimes are within each buffer.
If the spatial join tool doesn't work, you could try with this equivalent method :
right click on your buffer polygon in the context menu, select "join" in the drop box, select "join based on location"
If you really have a very large number of points, the only workaround that I see is to loop on each polygon, select by location and count the number of features (using modelbuilder or, better, arcpy)
