Oman is located in the Middle East, bordered by the Arabian Sea, Gulf of Oman, and Persian Gulf. The majority of Oman is covered by vast desert plains, with mountains located along the northern and southeastern coasts where most cities are. The climate is generally hot and dry inland, and humid along the coasts. While oil production is a major industry, Oman's economy is becoming less dependent on oil and focusing on other industries like construction, tourism, and manufacturing as oil resources decline. The population is over 3 million, with Omani Arabs and expat workers from South Asia and the Philippines comprising the majority. Islam is the dominant religion, with both Ibadhi and Sunni sects
