The country has an area of 33,774 square miles and a population of 8.2 million. There were no reliable statistics on membership in specific religious groups; however, according to official figures approximately 96 percent of the population is Muslim. The remainder of the population consists mostly of Russian Orthodox, Armenian Orthodox, followers of other Christian groups, Jews, and nonbelievers.
Among the Muslim majority, religious observance is relatively low, and Muslim identity tends to be based more on culture and ethnicity than religion; however, there has been a gradual growth in the number of observant Muslims. According to the State Committee on Work with Religious Structures (SCWRS), the Muslim population is approximately 65 percent Shi'a and 35 percent Sunni; traditionally, differences are not defined sharply.
The majority of Christians are Russian Orthodox whose identity, like that of Muslims, tends to be based as much on culture and ethnicity as on religion. Christians are concentrated in Baku and several other urban areas.
The great majority of the Jewish population, numbering approximately 20,000, lives in Baku. Much smaller communities exist in Guba and elsewhere.
Shi'a, Sunni, Russian Orthodox, and Jews are considered to be the country's "traditional" religious groups. Small congregations of Lutherans, Roman Catholics, Baptists, Molokans (Russian Orthodox Old Believers), Seventh-day Adventists, and Baha'is have been present for more than 100 years.
Since independence in 1991, a number of religious groups considered by the Government as foreign or "nontraditional" have established a presence, including "Wahhabi" and Salafist Muslims, Pentecostal and other evangelical Christians, including Jehovah's Witnesses, and Hare Krishnas. There are significant expatriate Christian communities in Baku.
