Look at the photo - notice how, even for most of the photo, it's broken into clusters. Minus a couple of individuals, you can draw circles around groups of white children and groups of black children. Either the photo has been artificially set up that way (highly unlikely), or this could be a good example of self-segregation. It is *noticeable* that we don't have an alternating pattern of white-black-white-black, but that we have pockets of white students clustered together, groups of black students clustered together, and a couple of exceptional cases (of black students around whites for the guy on the far bottom left, or white students around blacks for the girl on the right side of the cutout character). This goes to show, even at such a young age, it's clear in the minds of young people that there is a *difference* there, enough so that it leads to separation between the groups.
