On a related but separate issue, I would accept that the section dealing with the constituent parts is about Local Government.  However, neither the past nor the present title of the section indicates the section is primarily about local government.  Moreover, it is no more clear why local government would feature so prominently in an article about subdivisions.  There is of course the possibility that the subdivisions exist because of local government, but this is not stated anywhere in the article.  If that were the preferred reading, then the article as it now stands is inside out, or back to front, depending on your preferred colloquialism.  Is this article about subdivision or about local government?
