The country has an area of 631,000 square miles and a population of 71.6 million. The population is 98 percent Muslim; 89 percent is Shi'a and 9 percent Sunni (mostly Turkmen and Arabs, Baluchs, and Kurds living in the southwest, southeast, and northwest respectively). Non-Muslims account for 2 percent of the population. There are no official statistics available on the size of the Sufi Muslim population; however, some reports estimate between two million and five million persons practice Sufism.
Recent unofficial estimates from religious organizations claim that Baha'is, Jews, Christians, Sabean-Mandaeans, and Zoroastrians constitute two percent of the total population. The largest non-Muslim minority is the Baha'i religious group, which numbers 300,000 to 350,000. Unofficial estimates of the Jewish community's size vary from 25,000 to 30,000.
According to U.N. figures, 300,000 Christians live in the country, the majority of whom are ethnic Armenians. Unofficial estimates for the Assyrian Christian population are between 10,000 and 20,000. There are also Protestant denominations, including evangelical religious groups. Christian groups outside the country estimate the size of the Protestant Christian community to be less than 10,000, although many Protestant Christians reportedly practice in secret. Sabean-Mandaeans number 5,000 to 10,000. The Government regards Sabean-Mandaeans as Christians, and they are included among the three recognized religious minorities; however, Sabean-Mandaeans do not consider themselves Christians. The Government estimates there are 30,000 to 35,000 Zoroastrians, a primarily ethnic Persian minority; however, Zoroastrian groups claim to have 60,000 adherents. There are indications that members of all religious minorities are emigrating at a high rate, although it is unclear if the reasons for emigration are religious or related to overall poor economic conditions.
1. The Religious Characteristics of States Dataset Project: Government Religious Preference (GRP) measures government-level favoritism toward, and disfavor against, 30 religious denominations. A series of ordered categorical variables index the state's institutional favoritism in 28 different ways. The variables are combined to form five composite indices for five broad components of state-religion: official status, religious education, financial support, regulatory burdens, and freedom of practice. The five components' composites in turn are further combined into a single composite score, the GRP score. The RCS Data Project would like to acknowledge, recognize, and express our deepest gratitude for the significant contributions of Todd M. Johnson the principal investigator of the World Christian Database and the co-principal investigator of the World Religion Database.
2. The Religious Characteristics of States Dataset Project: Demographics reports the estimates of religious demographics, both country by country and region by region. The RCS was created to fulfill the unmet need for a dataset on the religious dimensions of countries of the world, with the state-year as the unit of observation. It estimates populations and percentages of adherents of 100 religious denominations including second level subdivision within Christianity and Islam. The RCS Data Project would like to acknowledge, recognize, and express our deepest gratitude for the significant contributions of Todd M. Johnson the principal investigator of the World Christian Database and the co-principal investigator of the World Religion Database.
3. The U.S. State Department's International Religious Freedom Report is submitted to Congress annually by the Department of State in compliance with Section 102(b) of the International Religious Freedom Act (IRFA) of 1998. This report supplements the most recent Human Rights Reports by providing additional detailed information with respect to matters involving international religious freedom. It includes individual country chapters on the status of religious freedom worldwide. A dataset with these and the other international measures highlighted on the country pages can be downloaded from this website. These State Department reports are open source.
