group of primary country divisions tier
The tier for areas that group several first-level divisions of one country into one named unit.
This tier holds areas that gather several first-level divisions of a country into one named unit: a group of states, a group of regions, a statistical macroregion.
Such an area covers whole divisions rather than cutting across them, which is what separates it from a zone. Its boundary follows from its members, so it changes only when the membership does.
The tier sits under the country and beside the first-level divisions it groups, never between them: a division still hangs under its country.
