Statistics by Country for Astigmatism
|
About these extrapolations of prevalence and incidence statistics for Astigmatism:
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 Astigmatism are typically based on US, UK, Canadian or Australian statistics.
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 Astigmatism statistics below refer to.
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 Astigmatism in that region.
About prevalence and incidence statistics in general for Astigmatism: The word 'prevalence' of Astigmatism usually means the estimated population of people who are managing Astigmatism at any given time (i.e. people with Astigmatism). The term 'incidence' of Astigmatism means the annual diagnosis rate, or the number of new cases of Astigmatism diagnosed each year (i.e. getting Astigmatism). 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. |
Prevalance of Astigmatism: 45 million Americans (dubious estimate based on "two thirds of people with myopia also have astigmatism")
Prevalance Rate for Astigmatism: approx 1 in 6 or 16.54% or 45 million people in USA [about data]
Extrapolation of Prevalence Rate of Astigmatism to Countries and Regions: The following table attempts to extrapolate the above prevalence rate for Astigmatism to the populations of various countries and regions. As discussed above, these prevalence extrapolations for Astigmatism are only estimates and may have limited relevance to the actual prevalence of Astigmatism in any region:
