so far only a small number of pregnant underage girls were found

4 or 5 out of the 400+, that's 4 or 5%

what's the number in mainstream society?

Irrelevant, because in mainstream society, if an underage girl gets
herself pregnant, it's usually consensual - with no one else involved
except a boy around her own age. Here, fully-grown adults consipired
to create this situation, by controlling and limiting the girls'
choices.

So more serious criminality was involved; their pregnancies resulted
from activity that more closely resembled non-statutory rape.
