About statistics:

This page presents a variety of statistics about Endometriosis. The term 'prevalence' of Endometriosis usually refers to the estimated population of people who are managing Endometriosis at any given time. The term 'incidence' of Endometriosis refers to the annual diagnosis rate, or the number of new cases of Endometriosis 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.
