That's because you've been sheltered from most of it; and most of the time it's "kept within the family," never made public, and simply swept under the rug -- so as to not "break apart the family" (at the cost of one victim).

People will allow all sorts of horrendous things to happen, if it serves their interests.

Father rapes his daughter? The mother refuses to believe it: thinks her daughter is only doing it for attention; doesn't want her "perfect" family image to get shattered (plus, daddy dearest pays the bills and funds her lifestyle). Same goes for extended family.

"It couldn't happen in our family." "You know how teenage girls are." "He would never do something like that. I've known him for decades."

Cognitively checking-out, because it's not their "problem." And other forms of dissonance.

Those are only the stats for pregnancy, though. I'm sure the incidence of sexual abuse without pregnancy is higher.

I’m 64 years old, so I’ve been around a while. Essentially every woman I have ever been close enough with to discuss these issues has reported either being sexually abused as a child or raped as an adult. As a young man I never realized how widespread this is.
