Are there statistics on the prevalence or non-prevalence of Parkinson's in particular parts of the U.S. and of the world?

Yes.

In my opinion the best is:

Neuroepidemiology. 2010;34(3):143-51. doi: 10.1159/000275491. Epub 2010 Jan 15.

Geographic and ethnic variation in Parkinson disease: a population-based study of US Medicare beneficiaries.

Wright Willis A, Evanoff BA, Lian M, Criswell SR, Racette BA.

The neurotalk Parkinson's forum has threads on other areas, including Spain and England.

I belong to this and can't make heads or tails of it.

I have tried to update 4 or 5 times over the past month or two, but the system has failed to acknowledge my efforts. Nothing changes.
