The country has an area of 4,254 square miles (11,020 km2) and a total population of more than 2.169 million, of whom one quarter are citizens. The population is predominantly Sunni. The majority of noncitizens are from South and Southeast Asian and Arab countries working on temporary employment contracts, accompanied by family members in some cases. Most noncitizens are Shi'a or Sunni Muslims, Christians, Hindus, Buddhists, or Bahá'ís. Most foreign workers and their families live near the major employment centers of Doha, Al Khor, Mesaieed, and Dukhan.
While the Government does not release demographic figures regarding religious affiliation, some membership figures are available from Christian community groups. Accordingly, the Christian community includes Roman Catholics (80,000), Eastern and Greek Orthodox, Anglicans (10,000), Copts (3,000), and other Protestants. The Hindu community is almost exclusively Indian, while Buddhists include South, Southeast, and East Asians. Most Bahá'ís come from Iran. Religion is not a criterion for citizenship, according to the
Nationality Law. However, nearly all Qatari citizens are either Shi'a or Sunni Muslims, except for at least one Christian and one Atheist, a few Bahá'ís, and their respective families who were granted citizenship.
No foreign missionary groups operated openly in the country.
