Approximately 1 million individuals in the USA are living with PD.1,2 According to data from the Parkinson’s Foundation Parkinson’s prevalence project (PPPP), 1.2  million people will be living with PD in the USA by 2030.1

Interestingly, there are geographic variations seen in PD prevalence.2,4 An analysis of US Medicare data suggested that urban populations in the USA tend to have a higher prevalence of PD than rural populations, and data suggest that there may be a concentration of the disease in the Midwest and Northeast regions, compared to other regions.4 The PPPP studies have found a greater incidence of PD in the ‘Rust Belt’ (parts of the northwestern and midwestern U.S. where industrial manufacturing has been a major economic activity), Southern California, Southeastern Texas, Central Pennsylvania and Florida.2
