It’s not missing, admin_level intentionally used only even numbers in 
case something was found to be between the defined levels.

Townships are at the same level as cities/towns/villages/other 
municipalities[1], [2].  I’m sure someone correct me if I’m wrong, but 
my understanding is you won’t find a chunk of land that is both 
“city|village|etc.” and “township” simultaneously; cities et al. can 
annex portions of townships easily, but they then are no longer part of 
that township.
