Because the original post said 3 decades ago. Which would be the 80s. Again, no one is making up stuff to try and make Chicago look bad here. You guys brought up the 3 decade time period, and I only said, "well, ok, let me look at the data since the 80s." There's nothing underhanded there guy.

And counting blacks since 2010, when you changed the definition, so that people who were called black in 1980, or 1990, or whatever, are no longer called black. Well duh. Yeah, if mixed kids are born in Chicago, and you guys call them, I don't know, whatever it is you call them. Then they won't be counted in your data as black. Is that surprising to you? So basically to me, I feel like you guys don't count any mixed blacks, and then are surprised that the number of blacks is going down? I mean come on man. That should be a no brainer. But the important thing here, is that no one really outside of Chicago would look at those people and say they are not black. And again, in 80 or 90 or maybe even 00, they counted them all as black in the census. That's all I'm saying.
