From Nikole Hannah-Jones’s phenomenally written and devastatingly sad Segregation Now: Investigating America’s Racial Divide:

In recent years, a new term, apartheid schools — meaning schools whose white population is 1 percent or less, schools like Central—has entered the scholarly lexicon. While most of these schools are in the Northeast and Midwest, some 12 percent of black students in the South and nearly a quarter in Alabama now attend such schools—a figure likely to rise as court oversight continues to wane. In 1972, due to strong federal enforcement, only about 25 percent of black students in the South attended schools in which at least nine out of 10 students were racial minorities. In districts released from desegregation orders between 1990 and 2011, 53 percent of black students now attend such schools, according to an analysis by ProPublica.
