Statistics by Country for Depressive disorders

Prevalance of Depressive disorders:

9.5 percent of adult Americans (NIMH)

Prevalance Rate for Depressive disorders:

approx 1 in 10 or 9.50% or 25.8 million people in USA [about data]

Extrapolation of Prevalence Rate of Depressive disorders to Countries and Regions:

WARNING! EXTRAPOLATION ONLY! NOT BASED ON COUNTRY-SPECIFIC DATA SOURCES. The following table attempts to extrapolate the above prevalence rate for Depressive disorders to the populations of various countries and regions. These prevalence extrapolations for Depressive disorders are only estimates, based on applying the prevalence rates from the US (or a similar country) to the population of other countries, and therefore may have very limited relevance to the actual prevalence of Depressive disorders in any region:

Incidence (annual) of Depressive disorders:

estimated 18.8 million American adults annually (NIMH)

Incidence Rate for Depressive disorders: approx 1 in 14 or 6.91% or 18.8 million people in USA [about data] Extrapolation of Incidence Rate for Depressive disorders to Countries and Regions: WARNING! EXTRAPOLATION ONLY. NOT BASED ON COUNTRY-SPECIFIC DATA SOURCES. The following table attempts to extrapolate the above incidence rate for Depressive disorders to the populations of various countries and regions. As discussed above, these incidence extrapolations for Depressive disorders are only estimates and may have very limited relevance to the actual incidence of Depressive disorders in any region:

About extrapolations of prevalence and incidence statistics for Depressive disorders:

WARNING! EXTRAPOLATED STATISTICS ONLY! Not based on data sources from individual countries. These statistics are calculated extrapolations of various prevalence or incidence rates against the populations of a particular country or region. The statistics used for prevalence/incidence of Depressive disorders are typically based on US, UK, Canadian or Australian prevalence or incidence statistics, which are then extrapolated using only the population of the other country. This extrapolation calculation is automated and does not take into account any genetic, cultural, environmental, social, racial or other differences across the various countries and regions for which the extrapolated Depressive disorders statistics below refer to. The extrapolation does not use data sources or statistics about any country other than its population. As such, these extrapolations may be highly inaccurate (especially for developing or third-world countries) and only give a general indication (or even a meaningless indication) as to the actual prevalence or incidence of Depressive disorders in that region. These statistics are presented only in the hope that they may be interesting to some people.

About prevalence and incidence statistics in general for Depressive disorders:

The word 'prevalence' of Depressive disorders usually means the estimated population of people who are managing Depressive disorders at any given time (i.e. people with Depressive disorders). The term 'incidence' of Depressive disorders means the annual diagnosis rate, or the number of new cases of Depressive disorders diagnosed each year (i.e. getting Depressive disorders). Hence, these two statistics types can differ: a short 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.
