Eastern Province, Saudi Arabia
The official language of Saudi Arabia is Arabic. The three main regional variants spoken by Saudis are Hejazi Arabic, Najdi Arabic, and Gulf Arabic. There are approximately 2 million Gulf Arabic speakers in Saudi Arabia, and the dialect is only spoken in the Eastern Province. The remaining Arabic speakers in the province speak one of the other two dialects, more commonly the Najdi dialect. Saudi Sign Language is the principal language of the deaf community. The large expatriate communities also speak their own languages, the most numerous of which are Indian languages, Filipino/Tagalog, Egyptian Arabic, Indonesian, Rohingya, and Urdu.Saudi Aramco, the state-owned oil producing company of Saudi Arabia, is based in Dhahran, which is located in the Eastern Province, and most decisions on oil policy and production that affect the global economy are made there. The kingdom's main oil and gas fields are mostly located in the Eastern Province, onshore and offshore. Notable among these are the Ghawar Field and the largest crude increment in the world. Petroleum from the fields is shipped to dozens of countries from the oil port of Ras Tanura and is also used as feedstock in numerous industrial plants in Jubail.
Hejazi Arabic
Notes:The varieties of Arabic spoken in the smaller towns and by the bedouin tribes in the Hejaz region are relatively under-studied. However, the speech of some tribes shows much closer affinity to other bedouin dialects, particularly those of neighboring Najd, than to those of the urban Hejazi cities. The dialects of northern Hejazi tribes merge into those of Jordan and Sinai, while the dialects in the south merge with those of 'Asir and Najd. Also, not all speakers of these bedouin dialects are figuratively nomadic bedouins; some are simply sedentary sections that live in rural areas, and thus speak dialects similar to those of their bedouin neighbors.
