Young boys circumcised, while older men intact. The exact trend? Only in South Korea you can get this kind of bizarre distribution.
There is a wide-variation of circumcision rate vs. age: what can we say, only in South Korea!
Words of caution: the low circumcision rate for 3 and 8 year old age groups do not mean that the circumcision rate is going down. These boys are waiting to be circumcised!
