from 2007, when WHO estimated that 664,500,000 males aged 15 and over were circumcised (30–33% global prevalence), and that 70% of circumcised men were Muslim. A study on male circumcision prevalence in 118 developing countries found that 69% of circumcised men were Muslim. Circumcision is most common in the Australia, Canada, Israel, New Zealand, the Muslim world, South Korea, the United States, and parts of Southeast Asia and Africa. It is relatively rare for non-religious reasons in Europe, Latin America, parts of Southern Africa and Oceania and most of non-Muslim Asia. Prevalence is near-universal in the Middle East and Central Asia. Non-religious circumcision in Asia, outside the Republic of Korea and the Philippines, is fairly rare, and prevalence is generally low (less than 20%) across Europe. Estimates for individual countries include Taiwan at 9% and Australia 58.7%. Prevalence in the United States and Canada is estimated at 75% and 30% respectively. Prevalence in Africa varies from less than 20% in some southern African countries to near universal in North and West Africa. Rates of circumcision over time have varied by country. As of 2021, Wolters Kluwer Health estimates that present circumcision incidence in the United States is 80%, and most are performed in the neonatal period for prophylactic reasons. Circumcision incidence in the U.S. has likely risen since 2012, when the AAP released a policy statement that was more positive on the topic. Hospital discharge surveys in the U.S. show lower numbers, although this is likely due to miscoding, circumcisions performed after hospital discharge, and those performed later in life. Canada has seen a slow decline since the early 1970s, possibly influenced by past statements from the AAP and the Canadian Pediatric Society in the 1970s that stated it was not medically necessary. In Australia, the rate declined in the 1970s and 80s, but has been increasing slowly as of 2004. In the United Kingdom, prevalence was likely to have been 20–30% in the 1940s but declined at the end of that decade. One possible reason may have been a 1949 British Medical Journal article which argued that there was no good medical reason for routine circumcision. The overall prevalence of circumcision in South Korea has increased markedly in the second half of the 20th century, rising from near zero around 1950 to about 60% in 2000, with the most significant jumps in the last two decades of that time
