Here's the government data I referenced, I am using my specific hometown neighborhood zipcode "11717", it's 94.5% between 2006-2008.

> Pregnancy rates are the number of pregnancies per 1,000 females age 15 to 19 years
95.46 pregnancies / 1000 females = 9.546%
(actually, you can't infer an exact percentage of girls who became pregnant from this statistic, as one female can have multiple pregnancies within a year, but you get what I mean)
Deleted comment
The person you replied to has deleted their comment so I guess maybe they were being an abusive asshole about it, which is certainly not needed.
* Nitpicking implies the things aren't important so I guess that's the wrong word, but I tried to be consistent with your comment.
