I was looking into this recently. The reported is a different number to those that have vanished or been found obducted. In the UK a child could simply go around a friends house, the other parents often assume that the child has permission. Then if the parent gets no news they call the Police. Often the child just turns up. I want to know the figures of children actually going missing and they are harder to find and difficult to verify. The number is ridiculously high anyway.
