Subdivision trees for types of subdivisions
All types of administrative divisions should be in two subclasses trees via subclass of (P279): one for its type and one for its country.
Subclass by type
Each type of administrative division should be have a type that is a subclass (or sub-subclass) of political territorial entity (Q1048835). Some examples of these trees are:
- U.S. state (Q35657) → federated state (Q107390) → state (Q7275) → political territorial entity (Q1048835)
- town of Japan (Q1059478) → municipality of Japan (Q1054813) → municipality (Q15284) → political territorial entity (Q1048835)

Subclass by country
Each type of administrative division should also be in a subclass specific to its country. These parent items are generally in the format "political divisions of X" and are subclasses of table of administrative divisions by country (Q1423994). For example:
- administrative territorial entity of Australia (Q4494320) is the parent class of state or territory of Australia (Q178712) and local government area of Australia (Q1867183).
- administrative territorial entity of the United States (Q852446) is the parent class of U.S. state (Q35657), county of the United States of America (Q47168), civil township (Q1394476), county-equivalent (Q1188782), and unincorporated territory of the United States (Q2107324).
