Hello All,
Actually, this may not be the case. Some states dissolve the township
association when an area is incorporated. While a city or village may
contain area that falls within a township, I am not sure whether the
association is made by the Census Bureau (they may report the stats for
the village or city, rather than the township).
Also, when I was in Arizona, we occasionally had snowbirds come in
asking for the name of their townships. While the Western states do have
the obligatory section, township and range layout, the townships often
are not named. Linda Zellmer

Hmmm....not exactly...
Everywhere in the USA belongs to exactly one Minor Civil Division. If I
am following this thread correctly, then the northern part of the City
of Mason, MI belongs to Alaiedon Township, while the southern part
belongs to Vevay Township. If you were to put MCD's in a GIS and do a
query for a point within the city of Mason, it would return "City of
Mason" and that's all.
There's another layer called "Census Designated Places/Incorporated
Places" that is not wall-to-wall. For the cities of Michigan, CDP
appears identical to MCD, but then take a look at the city of
Williamston. At first glance, it would appear to be partially in
Williamston Township, and partially in Wheatfield Township. But there
are a couple of polygons that are specifically labeled "Williamston
Township" south of certain fingers of the city. But if you draw a
horizontal line connecting these polygons, you cross a finger of
Wheatfield Township, but there is no boundary.
My conclusion: if you live in Williamston city, you better just know
what township you live in, because TIGER won't tell you.
