The Yardship is similar to property lines of an associated unit, be it a private home, named housing development, trailer park, strip mall, regular mall, associated Hutships. It is very similar to property lines, but does not represent a particular owner but rather a grouped unit or single independent unit.
Note the Yarship micro-political 'level' is variable from level 4.0 to level 5.0.
School districts are also variable zones that usually fall into the 7.0 range, but some public school districts fall into the 8.0 range as they cross county lines every so often. But School Districts are not considered micro-political units.
