About statistics:

This page presents a variety of statistics about Prader-Willi syndrome. The term 'prevalence' of Prader-Willi syndrome usually refers to the estimated population of people who are managing Prader-Willi syndrome at any given time. The term 'incidence' of Prader-Willi syndrome refers to the annual diagnosis rate, or the number of new cases of Prader-Willi syndrome diagnosed each year. Hence, these two statistics types can differ: a short-lived disease like flu can have high annual incidence but low prevalence, but a life-long disease like diabetes has a low annual incidence but high prevalence. For more information see about prevalence and incidence statistics.
