The country has an area of 32,300 square miles and a population of 4.8 million. An estimated 80 percent of the country's residents are noncitizens. Of the citizens, more than 85 percent are Sunni Muslim and an estimated 15 percent or fewer are Shi'a. Noncitizen residents are predominantly from South and Southeast Asia, although there are substantial numbers from the Middle East, Europe, Central Asia, and North America. According to the most recent Ministry of Economy census (2005), 76 percent of the total population is Muslim, 9 percent is Christian, and 15 percent is "other." According to unofficial figures, at least 15 percent of the resident population is Hindu, and 5 percent is Buddhist. Groups that constitute less than 5 percent of the population include Parsi, Baha'i, Sikh, and Jews. These estimates differ from census figures because census figures do not take into account "temporary" visitors and workers and they count Baha'is and Druze as Muslim.
