Statistics by Country for Hemorrhoids

Prevalance of Hemorrhoids:

10.4 million people in the USA 1983-87 (Digestive diseases in the United States: Epidemiology and Impact – NIH Publication No. 94-1447, NIDDK, 1994)

Prevalance Rate for Hemorrhoids:

approx 1 in 26 or 3.82% or 10.4 million people in USA [about data]

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

Incidence (annual) of Hemorrhoids:

1 million new cases in the USA 1983-87 (Digestive diseases in the United States: Epidemiology and Impact – NIH Publication No. 94-1447, NIDDK, 1994)

Incidence Rate for Hemorrhoids: approx 1 in 272 or 0.37% or 1 million people in USA [about data] Extrapolation of Incidence Rate for Hemorrhoids 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 Hemorrhoids to the populations of various countries and regions. As discussed above, these incidence extrapolations for Hemorrhoids are only estimates and may have very limited relevance to the actual incidence of Hemorrhoids in any region:

About extrapolations of prevalence and incidence statistics for Hemorrhoids:

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 Hemorrhoids 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 Hemorrhoids 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 Hemorrhoids 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 Hemorrhoids:

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