Topographic Map of Iran

Iran consists of the Iranian Plateau, with the exception of the coasts of the Caspian Sea and Khuzestan. It is one of the world’s most mountainous countries, its landscape dominated by rugged mountain ranges that separate various basins or plateaus from one another. The populous western part is the most mountainous, with ranges such as the Caucasus, Zagros, and Alborz, the last containing Mount Damavand, Iran’s highest point at 5,610 m (18,406 ft), which is also the highest mountain in Asia west of the Hindu Kush.

The northern part of Iran is covered by the lush lowland Caspian Hyrcanian mixed forests, located near the southern shores of the Caspian Sea.

The eastern part consists mostly of desert basins, such as the Kavir Desert, which is the country’s largest desert, and the Lut Desert, as well as some salt lakes.

The only large plains are found along the coast of the Caspian Sea and at the northern end of the Persian Gulf, where the country borders the mouth of the Arvand river. Smaller, discontinuous plains are found along the remaining coast of the Persian Gulf, the Strait of Hormuz, and the Gulf of Oman.


Iran’s economy is a mixture of central planning, state ownership of oil and other large enterprises, village agriculture, and small-scale private trading and service ventures. In 2017, GDP was $427.7 billion or $20,000 at PPP per capita. Iran is ranked as an upper-middle income economy by the World Bank. In the early 21st century, the service sector contributed the largest percentage of the GDP, followed by industry (mining and manufacturing) and agriculture.

The Central Bank of the Islamic Republic of Iran is responsible for developing and maintaining the Iranian rial, which serves as the country’s currency.

The government does not recognize trade unions other than the Islamic labor councils, which are subject to the approval of employers and the security services. The minimum wage in June 2013 was 487 million rials a month ($134). Unemployment has remained above 10% since 1997, and the unemployment rate for women is almost double that of the men.

In 2006, about 45% of the government’s budget came from oil and natural gas revenues, and 31% came from taxes and fees. As of 2007, Iran had earned $70 billion in foreign-exchange reserves, mostly (80%) from crude oil exports. Iranian budget deficits have been a chronic problem, mostly due to large-scale state subsidies, that include foodstuffs and especially gasoline, totaling more than $84 billion in 2008 for the energy sector alone. In 2010, the economic reform plan was approved by parliament to cut subsidies gradually and replace them with targeted social assistance. The objective is to move towards free market prices in a five-year period and increase productivity and social justice.
