Anyway pre-licence change there were contributions from roughly 24'000 mappers in the US extract.
To compare that with a random (:-)) other country: number of mappers with contributions at the same point in time as above: 6500, daily editors typically 50-60 (pop 8 million) so the ratio total mappers to daily mappers is roughly the same.
