Statistics by Country for Anencephaly

Incidence (annual) of Anencephaly:

less than 4,000 cases (the rate for spina bifida and anencephaly, NWHIC)

Incidence Rate for Anencephaly: approx 1 in 68,000 or 0.00% or 4,000 people in USA [about data] Extrapolation of Incidence Rate for Anencephaly 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 Anencephaly to the populations of various countries and regions. As discussed above, these incidence extrapolations for Anencephaly are only estimates and may have very limited relevance to the actual incidence of Anencephaly in any region:

About extrapolations of prevalence and incidence statistics for Anencephaly:

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 Anencephaly 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 Anencephaly 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 Anencephaly 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 Anencephaly:

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