Census bureau "census designated palces" unfortunately do not
necessarily match legally defined unincorporated townships and the
like. There are innumerable townships across the middle part of the
country which in no way conform to population patterns, but to the
six-mile-square patterning. On the other hand, census data should
work fine east of the Appalachians, where essentially everything is
incorporated...

I would go to the GIS offices for each state looking for this data.
For one thing, it's likely to be more current than what the Feds
have, given that the information would most likely flow from the
states in the first place. Someone ought to put up a basic link page
to these GIS offices outlining what is available...
