Qatar, officially State of Qatar, is an independent emirate on a largely barren peninsula in the Persian Gulf, bordering Saudi Arabia and the United Arab Emirates. The capital is Doha. The economy of Qatar is dominated by oil and natural gas, which accounts for 70% of export income. Oil and gas revenues have been used to diversify the economy, including the development of chemicals, steel, cement, and fertilizer industries and banking. A minority (15%) of the population are Qataris (Arabs of the Wahhabi sect of Islam); the rest are largely other Arabs, Pakistanis, Indians, and Iranians. Arabic is the official language, but English is also widely spoken. The country is a monarchy.
