approx 1 in 82 or 1.21% or 3.3 million people in USA [about data]

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

About extrapolations of prevalence and incidence statistics for ADHD:

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 ADHD 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 ADHD 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 ADHD 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 ADHD:

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