    Adjacent zip code analysis

    alex rozier

      So I've got some Zip Code data from the Census, and I want to compare data from each Zip Code to the Zip Codes directly next to it (eg: ZIp Code 12345 has an 11% higher graduation rate than all the Zip Codes next to it). Since Zip Codes have different number of sides and different shapes, I'm not sure you could tell which ones are touching just by using a formula or something like that. I guess this could apply to counties too. I read about people doing 'proximity analysis' in Tableau, but I wasn't sure if that'd be the best strategy here. Just wondering if anyone has any ideas, any suggestions are appreciated! Thanks!
