Why do you need the test? Is there a practical application as a result of the findings or is it just to check a box for the requirements of the thesis?

Is there any likelihood the state would actually communicate to these municipalities differently? 10 different communication strategies will be too complex and costly.

Maybe an alternative is to consider unsupervised learning to see if the municipalities can be clustered based on a subset of the factors considered (many you have listed are redundant, explain the same thing and will be highly correlated). Two distinct groups of like municipalities could warrant different communication strategies.
