Statistics by Country for Lactose Intolerance

About these extrapolations of prevalence and incidence statistics for Lactose Intolerance: 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 Lactose Intolerance 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 Lactose Intolerance 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 Lactose Intolerance in that region.

About prevalence and incidence statistics in general for Lactose Intolerance: The word 'prevalence' of Lactose Intolerance usually means the estimated population of people who are managing Lactose Intolerance at any given time (i.e. people with Lactose Intolerance). The term 'incidence' of Lactose Intolerance means the annual diagnosis rate, or the number of new cases of Lactose Intolerance diagnosed each year (i.e. getting Lactose Intolerance). 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 Lactose Intolerance: 30 million people to 50 million people (NIDDK 1994); about 25% of population (1994/NIDDK)
Prevalance Rate for Lactose Intolerance: approx 1 in 9 or 11.03% or 30 million people in USA [about data]
Extrapolation of Prevalence Rate of Lactose Intolerance to Countries and Regions: The following table attempts to extrapolate the above prevalence rate for Lactose Intolerance to the populations of various countries and regions. As discussed above, these prevalence extrapolations for Lactose Intolerance are only estimates and may have limited relevance to the actual prevalence of Lactose Intolerance in any region:
