I have been trying to group census areas into groups of approximately 15.000 people in the Spanish province of Alicante. I have just discovered the Districting Add-in and have spent all day trying to figure it put. I am currently using ArcMap 10.2.2.
I already have the shapefiles with the census areas and the total populations of those areas, as well as the amount of men and women, associated with their corresponding area.
When using the tool, I load the mentioned census shape file with all the data, use the code of each area as key field and the total population as the universe and optimal-value field. It doesn't matter the number of districts I choose to create (the number would have to be 125 , as the target value is 15000). When I finish using the tool, the output is a single Unassigned district with the totality of the population. I have started editing the district plan and selecting the areas manually, but it is overconsuming both my time and my patience.
I have uploaded a Screenshot with the resulting map. I would appreciate any input on the issue.
Thanks a lot,
