A national survey on sexual attitudes in 2000 found that 15.8% of men or boys in the United Kingdom (ages 16–44) were circumcised by their parents' choosing. 11.7% of 16- to 19-year-olds, and 19.6% of 40- to 44-year-olds said they had been circumcised. Apart from black Caribbeans, men born overseas were more likely to be circumcised. Rickwood "et al." reported that the proportion of English boys circumcised for medical reasons had fallen from 35% in the early 1930s to 6.5% by the mid-1980s. an estimated 3.8% of male children in the UK were being circumcised for medical reasons by the age of 15. The researchers stated that too many boys, especially under the age of 5, were still being circumcised because of a misdiagnosis of phimosis. They called for a target to reduce the percentage to 2%.
