Iran has a fairy diversified economy. Although the country is one of the world’s major oil producers, the oil sector accounts only for 23 percent of GDP. The largest contributor to the GDP is services (around 50 percent of total output). Within services, the most important are real estate and specialized and professional services (14 percent of GDP); trade, restaurants and hotels (12 percent of GDP) and public services (10 percent of GDP). Manufacturing and mining constitute 20 percent of GDP and agriculture 10 percent.
