Why is Marion County Indiana divided into nine townships? Doesn't Indianapolis cover all of the county?
Cities and townships in the Midwest are not necessarily coterminus. When Indy was extended in 1970, a number of communities also in Marion were not incorporated. The unification did not extend to the townships either, and they maintain their status within the incorporated municipality.
The status of Marion County under Unigov is somewhat anomalous. All areas are to some extent administratively associated with Indianapolis; the extent to which this is the case varies by area.
