Well yes it is possible, however is essentially boils down to analysing
a full history extract of the US, the changeset bounding boxes are just
too unreliable to be useful (further: such an analysis just counts
people who mapped in the US which is naturally a larger number than bona
fida US mappers). 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.
