The Jewish population of greater New York City rose ten percent in the last decade, to 1.54 million, a study found.
Two-thirds of that growth came from two haredi Orthodox neighborhoods, according to data released Friday by UJA-Federation of New York.
The data is part of a second batch of information from the demographic survey UJA-Federation conducted of the local Jewish population in 2012. The full report includes more detailed geographic data on the Jewish residents in UJA-Federation's catchment area, which includes the five boroughs of New York City, Long Island, and Westchester County. The greater New York City region is home to the largest Jewish community in North America.
According to the study, most of the ten percent increase since 2002 occurred in the predominantly haredi Orthodox Brooklyn neighborhoods of Borough Park and Williamsburg.
The number of Jews living in Borough Park, home to the Bobov Chasidic sect and several others haredi communities, rose by 71 percent. In Williamsburg, the seat of the Satmar Chasidic sect, the population increased by 41 percent.
Other parts of the city also saw a dramatic rise in Jewish population. The number of Jews living in the northern Manhattan neighborhood of Washington Heights sky-rocketed by 144 percent.
The Bronx, a former bastion of Jewish life that had seen a long period of decline, is also rebounding. The number of Jews in the northern borough rose from 45,100 to 53,900 in 2012.
"The geographic profile give us essential current information so we can best respond with laser-like focus to regional and communal needs," said John Ruskay, the executive vice president and CEO of UJA-Federation of New York. "We, along with our network of agencies, area synagogues, day schools and many other communal institutions will use this data for planning to meet current and future needs of the Jewish community."
