My first post, so let me quickly say: THIS DATABASE ROCKS! I'm simply amazed by the level of detail. Much admiration to everyone that build it.
Region names in Poland contain polish word "region" (Województwo) in them. It's the same, as if regions in US would be called:
5090174 | New Hampshire Region
5101760 | New Jersey Region
5128638 | New York Region
5165418 | Ohio Region
To be sure, by "region" I mean: A.ADM1 first-order administrative division.
