known_territory_subdivisions() :: %{required(atom()) => list()}

Returns the map of territories and subdivisions and their child subdivsions.

The subdivision codes designate a subdivision of a country or region. They are called various names, such as a state in the United States, or a province in Canada.

The codes in CLDR are based on ISO 3166-2 subdivision codes. The ISO codes have a region code followed by a hyphen, then a suffix consisting of 1..3 ASCII letters or digits.

The CLDR codes are designed to work in a unicode_locale_id (BCP47), and are thus all lowercase, with no hyphen. For example, the following are valid, and mean “English as used in California, USA”.

en-u-sd-usca
en-US-u-sd-usca

CLDR has additional subdivision codes. These may start with a 3-digit region code or use a suffix of 4 ASCII letters or digits, so they will not collide with the ISO codes. Subdivision codes for unknown values are the region code plus "zzzz", such as "uszzzz" for an unknown subdivision of the US. Other codes may be added for stability.
