Federal agency, state, state department, county (parish in LA), city,
township, town, village. All are political subdivision's.

Cities and the like are corporations.

If any political subdivision on a map counts, then school teachers,
firefighters, garbage collectors, and a vast number of other people
can fly without certificates and ignore the FARs.
