Integration without blacks: In the past 40 years researchers have found nearly a three-fold increase in the share of integrated New York City neighborhoods with a mix of whites, Hispanics and Asians but few, if any, blacks

At the same time, the share of integrated neighborhoods in which blacks comprised at least 10% of the residents fell by about a third, researchers Ronald J.O. Flores and Arun Peter Lobo have reported. In New York City, there is an emerging black/non-black color line, where Asians and Hispanics are increasingly aligned with whites while distancing themselves from blacks. Between 1970 and 2010, the share of whites - nearly two-thirds of the NYC population in 1970 - fell by about half to roughly 33%, while the proportion of blacks remained relatively stable at about 23%. At the same time, the city’s Hispanic population doubled to 28% and the Asian share grew more than six fold to 13%.
