Geographic ownership
USA Rugby lists 19 geographic-union contacts, while USA Club Rugby's reviewed XVs map assigns 16 owners to four Super Regions. Alaska, Hawaii and Montana are not assigned on that map, and the Midwest labels and local-area totals differ between the two owner sources.
Local owners remain separate
Geographic unions administer different local competitions and qualification routes. Frostlete does not combine them into one national table or infer missing assignments from geography.
