Seventy years ago this week, the U.S. Supreme Court ruled separating children in schools by race was unconstitutional. On paper, that decision 鈥 the fabled Brown v. Board of Education, taught in most every American classroom 鈥 still stands.
But for decades, American schools have been re-segregating. The country is more diverse than it ever has been, with students more exposed to classmates from different backgrounds. Still, around 4 out of 10 Black and Hispanic students attend schools where almost every one of their classmates is another student of color.
