Haredi Judaism
Haredi Judaism is not an institutionally cohesive or homogeneous group, but comprises a diversity of spiritual and cultural orientations, generally divided into a broad range of Hasidic sects, Litvishe-Yeshivish streams from Eastern Europe, and Oriental Sephardic Haredim. These groups often differ significantly from one another in their specific ideologies and lifestyles, as well as the degree of stringency in religious practice, rigidity of religious philosophy, and isolation from the general culture that they maintain.
Islam by country
Islam is divided into two major religious denominations: Sunni and Shi'a. Of the total Muslim population, 87–90% are Sunni and 10–13% are Shi'a. Most Shi'as (between 68% and 80%) live in mainly four countries: Iran, Azerbaijan, Bahrain and Iraq.
Today, many of the Shia sects are extinct. The major surviving Imamah-Muslim Sects are Usulism (with nearly more than 10%), Nizari Ismailism (with nearly more than 1%) and Alevism (with slightly more than 0.5% but less than 1%). The other existing groups include Zaydi Shi'a of Yemen whose population is nearly more than 0.5% of the world's Muslim population, Musta’li Ismaili (with nearly 0.1% whose Taiyabi adherents reside in Sindh and Gujarat in South Asia. There are also significant diaspora populations in Europe, North America, the Far East and East Africa), and Ibadis from the Kharijites whose population has diminished to a level below 0.15%. On the other hand, new Muslim sects like the Nation of Islam, Ahmadi Muslims (with nearly around 1%), non-denominational Muslims, Quranist Muslims and Wahhabis (with nearly around 1-2% of the world's total Muslim population) were later independently developed.
