Via Emily Badger, here's an interesting chart showing which countries are most open with national data. Obviously rich countries do best at this kind of statistical recordkeeping, but some rich countries do better than others, and the US is one of the best. In fact, it would be the best if not for the fact that corporate registration is a state function, and the US therefore scores approximately zero for its lack of a national corporate registry database. Full data for all countries is here. Enjoy.
