I have at my disposal the address/zip information for my client's stores, a master list of all U.S. Zip Codes. I just want to extract from ArCGIS Maps a list of zip codes within a 15 mile radius of my client's stores, as well as population in those zips. Seems simple enough, but I'm struggling. Any and all help is welcome and appreciated!
Select by location for the specified distance relative to you clients store location. Select by graphic with you drawing the the circle.
The population is a little more involved; obviously you'll need to obtain sound population data, (blocks, block groups, tracts, whatever granularity you choose to work with) and then geoprocess the population data into the zip data.
A word of caution; population data assumes a smooth distribution across the given polygon. You'll need to proportion that population to your zip polygons: what percentage of the original population polygon area is now in the zip polygon * population.....
