Now 16, Catherine is one of 142 students from Arlington's 2,693-student [Arlington] Sam Houston High School who are either new or expecting parents. More than half are Hispanic.
Let's say half of the 2693 students are female and, we'll assume, capable of being pregnant. That leaves 142/1347 or 10.5% of the female population. (Edit: I wished I had thought about calling it a "government educational compound" and wondering if CPS will raid it.)
Edit: Heck with that, just saw that Jim McKay has passed away. As a kid, that's a voice I heard every Saturday afternoon.
Edit #2: Man, this is turning into random thoughts as I just ran across the following. I had that toy as a kid. It'd go about six feet and fall over.
