Perhaps, but I doubt it. For the most part, you will see blacks with blacks, whites with whites, and Hispanics with Hispanics. This is a general statement which does not hold true in all cases.
I have lived and worked in Illinois for almost 40 years and have experienced voluntary segregation in the work place and in factory cafeterias and in society as a whole.
Last Feb. after going to Mardi Gras my wife and I stopped to eat at a resturant just north of New Orleans, while there a work crew of some sort came in, there were about 20 of them and obviously they were there to have breakfast before starting work. The crew was half white half black and I expected they would seat themselves along racial lines. What happened however was that they seated themselves at tables for four on an almost 50/50 split. They couldn't have been more racially integrated if they tried.
Their time there was full of laughing and talking and having a good time. It impressed me because in 40 years I had never seen anything like it in the north.
