About statistics: This page presents a variety of statistics about Anxiety Disorders.

The term 'incidence' of Anxiety Disorders refers to the annual diagnosis rate, or the number of new cases of Anxiety Disorders 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.
