It's disturbing that American schools remain deeply segregated by race more than half a century after Brown v. Board—given all we know about the damaging effects of segregation on kids.
What's even more disturbing, though, is that U.S. schools are more segregated now than they were twenty year ago. If you were to draw a line graph of school integration, it would show years of steady progress starting in the 1960s and then years of blacksliding beginning in the 1990s.
