By sport

How this list was assembled

1. One Overpass query per state, so a club's state is known by construction and never inferred.
2. Anything that is ground rather than an organisation — a pitch, a court, a municipal pool — is dropped. 40,190 records did not survive that test.
3. Records sharing a name within 250 m are merged as one venue, keeping the richer copy — 791 here.
4. Each club is matched to the nearest named city inside its own state, capped by settlement size, or left unassigned.
5. Nothing is ranked, weighted or promoted. No club can pay to move.

region  = the query it came from        (certain)
city    = nearest named place, same region, within cap
rank    = none
