Statistics by Country for Bipolar disorder

Prevalance of Bipolar disorder:

1.2 percent of the population; 2.3 million adult Americans (NIMH)

Prevalance Rate for Bipolar disorder:

approx 1 in 83 or 1.20% or 3.3 million people in USA [about data]

Extrapolation of Prevalence Rate of Bipolar disorder 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 Bipolar disorder to the populations of various countries and regions. These prevalence extrapolations for Bipolar disorder 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 Bipolar disorder in any region:

About extrapolations of prevalence and incidence statistics for Bipolar disorder:

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 Bipolar disorder 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 Bipolar disorder 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 Bipolar disorder 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 Bipolar disorder:

The word 'prevalence' of Bipolar disorder usually means the estimated population of people who are managing Bipolar disorder at any given time (i.e. people with Bipolar disorder). The term 'incidence' of Bipolar disorder means the annual diagnosis rate, or the number of new cases of Bipolar disorder diagnosed each year (i.e. getting Bipolar disorder). 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.
