PWS occurs in 1 out of approximately 12,000 - 15,000, which classifies it as a rare disease. According to the Office Of Rare Disease Research (a division of the National Institutes for Health) "A rare (or orphan) disease is generally considered to have a prevalence of fewer than 200,000 affected individuals in the United States." Given the incident rate and population of the USA there's around 20,000 - 26,000 people in the USA who have PWS.
