  • How do you know the Geocorr results aren't "accurate"? Do you have something to compare it to?

  • Personally I didn't see any accuracy problems, though it took me a few tries to get just the right proportion variables set so I saw what I wanted to see as a proportion: city X is y percent of CD Z by population or area etc. The ones I checked did check out, though I did wonder about a few really tiny population numbers like Joliet IL having 3.05 people in CD 16, but that could be an artifact of many things like parkland or a bit of near-vacant property that gets thrown in
