Prevalance of Depressive disorders:
In any given 1-year period, 9.5 percent of the population, or about
18.8 million American adults, suffer from a depressive illness.5
The economic cost for this disorder is high, but the cost in human
suffering cannot be estimated. Depressive illnesses often interfere with
normal functioning and cause pain and suffering not only to those who have
a disorder, but also to those who care about them. Serious depression can
destroy family life as well as the life of the ill person. But much of
this suffering is unnecessary.

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