Not as far as I know. I don't think, first, that the segregation is quite as severe. I did live in Chicago in the 1970s and the segregation there was absolutely extreme. You could go block by block. I don't think the informal segregation in Egypt is nearly that strong, nor are there the same socio-economic differences laid on top, nor is it always obvious when you see somebody on the street that somebody is Muslim or Christian.
I would say that it's probably less severe than Detroit, but it is still fairly marked. There are areas, as I say, where I don't think they're exclusively Christian areas, but there would be areas where you would find a heavy Christian concentration, and areas of the country where you would find very few Christians at all.
