I find it interesting that the schools are 67% black, considering the fact that da Burgh is only about 20% black TOPS (maybe a little less), and that parochial schools are probably closing there like they are everywhere else.
You are right. I may be a little off with the number, but it is close to that-—ahh, it was 60% in 2004-05: http://www.cgcs.org/BTO7/Pittsburgh.pdf
