Districts such as the Delancey Street and East Broadway sections cover the Great Ghetto of the East Side, while the West Side and Harlem Districts represent the neighborhoods which are the residential goals of the prosperous Jews of New York.
It has been stated that there are districts in which the density of Jewish population is more than 300,000 per square mile, which is more than 2,150 to the usual square city block. There are 19 neighborhoods in which the density is more than 200,000 to the square mile (1,430 to the square block); and 36 neighborhoods in which the density is more than 100,000 to the square mile (715 to the square block).
The average density of the general population for New York City both Jewish and non-Jewish, in 1915, was about 16,000 to the square mile, or 107 to the square block. More than one-third of the Jews, about 38 per cent, that is, 570,000 Jews, live on one per cent of the area of New York. If all New York’s population were as dense as is the Jewish population of the congested districts, the City would have almost as many inhabitants as the whole United States, or about 95,000,000.
These figures dimly portray the overcrowding which has resulted from the terrific influx of Russian-Polish
