The 469-page study published last year was carried out by a team of sociologists from the United Jewish Appeal Federation of New York.
They found that the Jewish population of New York had grown by 10% in the last 10 years, to some 1.5 million people, cementing its status as the largest metropolitan Jewish community outside of Israel.
The Bronx, a former Jewish stronghold which had seen a long period of decline, is now rebounding, according to the study.
More than 6,000 people in 26 primary areas were interviewed to compile the study, which included parts of Long Island and Westchester County as well as New York City.
