The Bureau of the Census enumerates respondents on the date of the decennial census as residing within the legal limits of municipalities, county subdivisions, counties, States, and equivalent areas as those limits exist on January 1, 2010. Sec. 70.2 ``Municipality'' and ``county subdivision'' defined forcensus purposes.
For the purposes of this part, the Bureau of the Census defines ``municipalities'' and ``county subdivisions'' to include the areas identified as incorporated places (such as cities and villages) and minor civil divisions (such as townships and magisterial districts).
