Black Girls Matter: Pushed Out, Overpoliced and UnderprotectedStudy by Columbia University Law professor Kimberle Crenshaw and colleagues. They examined data from public schools in Boston and New York City, and the results are startling: Girls of color, and especially black girls, are subject to discipline that is harsher and more frequent than that of their white peers, and are six times more likely to be suspended than white girls. The racial disparities in punishment are greater for girls than for boys.
