Most Saudis are ethnically [[Arab]]. Some are of mixed ethnic origin and are descended from Turks, Iranians, Indonesians, Indians, Africans, and others, most of whom immigrated as pilgrims and reside in the Hijaz region along the Red Sea coast. Many Arabs from nearby countries are employed in the kingdom. There also are significant numbers of Asian expatriates mostly from India, Pakistan, Bangladesh, Indonesia, and the Philippines. There are less than 100,000 Westerners in Saudi Arabia.

Saudi oil reserves are the largest in the world, and Saudi Arabia is the world's leading oil producer and exporter. Oil accounts for more than 90% of the country's exports and nearly 75% of government revenues. Proven reserves are estimated to be 263 billion barrels, about one-quarter of world oil reserves.
More than 95% of all Saudi oil is produced on behalf of the Saudi Government by the parastatal giant [[Saudi ARAMCO]]. In June 1993, Saudi ARAMCO absorbed the state marketing and refining company (SAMAREC), becoming the world's largest fully integrated oil company. Most Saudi oil exports move by tanker from Gulf terminals at Ras Tanura and Ju'aymah. The remaining oil exports are transported via the east-west pipeline across the kingdom to the Red Sea port of Yanbu.
Due to a sharp rise in petroleum revenues in 1974 following the 1973 Arab-Israeli war, Saudi Arabia became one of the fastest-growing economies in the world. It enjoyed a substantial surplus in its overall trade with other countries; imports increased rapidly; and ample government revenues were available for development, defense, and aid to other Arab and Islamic countries.
