blocks. Although the neighborhood was racially segregated, there were more attempts at improved quality of life, public mixing, and solidarity between black and Jewish neighbors than could be found in most other neighborhoods. However, due to socioeconomic barriers imposed by the disparities between the two populations, most of these improvements never came. Compounding the matter, the newly arrived African-American residents were mainly industrial workers who had moved to Brownsville just as the area's factories were going out of business, so the black residents were more economically disadvantaged than the Jews who had historically lived in Brownsville. Finally, although both blacks and Jews living in Brownsville had been subject to ethnic discrimination, the situation for blacks was worse, as they were banned from some public places where Jews were allowed, and the New York City Police Department (NYPD) generally behaved more harshly toward blacks than toward Jews. The breaking point for the area's Jewish population came about in the 1950s, when the New York City Housing Authority decided to build more new public housing developments in blighted portions of Brownsville. The Jewish population quickly moved out, even though the new NYCHA developments were actually in better condition than the old wooden tenements. Citing increased crime and their desire for social mobility, Jews left Brownsville en masse, with many black and Latino residents moving in, especially into the area's housing developments. For instance, in the Van Dyke Houses, the black population in 1956 was 57% and the white population that year was 43%, with a little over one percent of residents receiving welfare benefits. Seven years later, 72% of the residents were black, 15% Puerto Rican, and the development had the highest rate of per-capita arrests of any housing development citywide. Through the 1960s, its population became largely African American, and Brownsville's unemployment rate was 17 percent, twice the city's as a whole. The newly majority-black Brownsville neighborhood had few community institutions or economic opportunities. It lacked a middle class, and its residents did not own the businesses they relied upon. In his book Brownsville, Brooklyn: Blacks, Jews, and the Changing Face of the Ghetto, W.E. Pritchett described the neighborhood as a "ghetto" whose quality of life was declining by the year. The NYCHA housing encouraged the creation of an African-American and Latino population that was poorer than the Jewish population it replaced.
