Most of these children would attend better schools than those in the South and, as a whole, outperform their southern white counterparts and nearly match the scores of northern-born blacks within a few years of arrival. Studies conducted in the early 1930s found that, after four years in the North, the children of black migrants to New York were scoring nearly as well as northern-born blacks who were “almost exactly at the norm for white children,” wrote Otto Klineberg, a leading psychologist of the era at Columbia University.
