:::Unfortunately, "circumcision rate" seems ambiguous, leaning toward incidence of new circumcisions rather than prevalence, which is what the WHO is estimating.  How about: Percentage of males over 15 who have been circumcised, according to United Nations (WHO/UNAIDS) estimates.  (Pale blue, 0%-20%; medium blue, 20%-80%; dark blue, 80%-100%.)  Still have to fix the "no data" regions, but otherwise that would seem to be a fine addition to the article.
