Map 
No doubt footnote no.1 correctly ascribes the information on the map to the WHO but clearly the WHO is not the appropriate authority given that the UN as we all know deals with countries' self-reporting. May I point out that Malaysia and Indonesia, which are described as Muslim countries (as they officially indeed are), contain very substantial Christian, Buddhist and Hindu minorities. (See the CIA World Fact Book .) Moreover, many such minorities are considerably to be identified by region. North Borneo and New Guinea, for example, are very large geographical areas in Malaysia and Indonesia which only have a marginal Muslim presence; the Moluccas in Indonesia are at least 50% Christian; Bali is famously Hindu. Overall, Malaysia is some 60% Muslim and clearly does not belong in the plus-80% circumcised category as it appears on the map. But given the geographical spread of these countries and vast disparity of cultures and religions across the Indonesian Archipelago, it is surely meaningless to describe these countries in such a way. One is reminded of the generalisation in a former version of this article as to aboriginal Australians based, it seems, on certain academic studies of remote communities which did not at all constitute a valid observation as to aboriginal Australians as a whole.
