Satan
Each sect of Judaism has its own interpretation of Satan's identity. Conservative Judaism generally rejects the Talmudic interpretation of Satan as a metaphor for the "yetzer hara", and regard him as a literal agent of God. Orthodox Judaism, on the other hand, outwardly embraces Talmudic teachings on Satan, and involves Satan in religious life far more inclusively than other sects. Satan is mentioned explicitly in some daily prayers, including during Shacharit and certain post-meal benedictions, as described in Talmud and the Jewish Code of Law. In Reform Judaism, Satan is generally seen in his Talmudic role as a metaphor for the "yetzer hara" and the symbolic representation of innate human qualities such as selfishness.
Hasidic Judaism
In 2016, a study conducted by Prof. Marcin Wodziński, drawing from the courts' own internal phone-books and other resources, located 129,213 Hasidic households worldwide, about 5% of the estimated total Jewish population. Of those, 62,000 resided in Israel and 53,500 in the United States, 5,500 in Britain and 3,400 in Canada. In Israel, the largest Hasidic concentrations are in the Ultra-Orthodox neighbourhoods of Jerusalem – including Ramot Alon, Batei Ungarin et cetera – in the cities of Bnei Brak and El'ad, and in the West Bank settlements of Modi'in Illit and Beitar Illit. There is considerable presence in other specifically Orthodox municipalities or enclaves, like Kiryat Sanz, Netanya. In the United States, most Hasidim reside in New York, though there are small communities across the entire country. In Brooklyn, Borough Park, Williamsburg, and Crown Heights all house a particularly large population. So does the hamlet of Monsey in upstate New York. In the same region, New Square and Kiryas Joel are rapidly growing all-Hasidic enclaves, one founded by the Skver dynasty and the other by Satmar. In Britain, Stamford Hill is home to the largest Hasidic community in the country, and there are others in London and Prestwich in Manchester. In Canada, Kiryas Tosh is a settlement populated entirely by Tosh Hasidim, and there are more adherents of other sects in and around Montreal.
