I have a polygon shapefile that I would like to dissolve on a field called FID_merged (see below). For each dissolved polygon I would like to summarize a list of the countries.
I am using ArcGIS 10.3 and see that the only option for text-field statistics are first and last. How could dissolve on FID_merged and still maintain a list of all the countries for that FID_merged?
I am open to other non-esri solutions.
