Americans still appear to believe in the value of integrated education. A 2017 poll by Phi Delta Kappa, the professional organization for educators, found that 70 percent of parents would like to have their child in a racially diverse school. But 57 percent prize proximity over diversity. Only one-quarter of those who’d like a diverse school say they’d be willing to make a longer commute to get to one. Our persistently segregated neighborhoods make that a challenge across the nation.
