Obligatory shout out to us in there of course. Remember this graphic on local governments in Southwestern Pennsylvania.
I have not updated my page on local government organization here in some time. Still lots of references of note there. Since nothing ever really changes, it is all technically current info; just as it will be in a decade. More fun is just a reposting of my graphic of all local governments in Pennsylvania below. And for the completely pathological, see the United States' version.
