In 2002, an estimated 972,000 Ashkenazi Jews lived in New York City and constituted about 12% of the city's population. New York City is also home to the world headquarters of the Chabad, Bobover, and Satmar branches of Hasidism, and other Haredi branches of Judaism. While three-quarters of New York Jews do not consider themselves religiously observant, the Orthodox community is rapidly growing due to the high birth rates of Hasidic Jews, while the numbers of Conservative and Reform Jews are declining.
