Iran is divided into thirty provinces (ostān), each governed by an appointed governor (استاندار, ostāndār). The provinces are divided into counties (shahrestān), and subdivided into districts (bakhsh) and sub-districts (dehestān).

Iran has one of the highest urban growth rates in the world. From 1950 to 2002, the urban proportion of the population increased from 27% to 60%.The United Nations predicts that by 2030, 80% of the population will be urban.Most internal migrants have settled near the cities of Tehran, Isfahan, Ahvaz, and Qom. The listed populations are from the 2006/07 (1385 AP) census.Tehran, with population of 7,705,036, is the largest city in Iran and is the Capital city. Tehran is home to around 11% of Iran's population. Tehran, like many big cities, suffers from severe air pollution. It is the hub of the country's communication and transport network.

Mashhad, with a population of 2,410,800 million, is the second largest Iranian city and the centre of the province of Razavi Khorasan. Mashhad is one of the holiest Shi'a cities in the world as it is the site of the Imam Reza shrine. It is the centre of tourism in Iran and between 15 and 20 million pilgrims go to the Imam Reza's shrine every year. Another major Iranian city is Isfahan (population 1,583,609), which is the capital of Isfahan Province. The Naghsh-e Jahan Square in Isfahan has been designated by UNESCO as a World Heritage Site. The city contains a wide variety of Islamic architectural sites ranging from the eleventh to the 19th century.

The growth of suburb area around the city has turned Isfahan to the second most populous metropolitan area (3,430,353). The fourth major city of Iran is Tabriz (population 1,378,935), the capital of the East Azarbaijan province, which is also the second industrial city of Iran after Tehran. Tabriz had been the second largest city in Iran until the late 1960s and one of its former capitals and residence of the crown prince under the Qajar dynasty. The city has proven extremely influential in the country’s recent history. The fifth major city is Karaj (population 1,377,450), located in Tehran province and situated 20 km west of Tehran, at the foot of Alborz mountains; however, the city is increasingly becoming an extension of metropolitan Tehran.

Other major Iranian city is Shiraz (population 1,214,808), which is the capital of Fars Province. The ancient Persians were present in the region from about the 9th century BC, and became rulers of a large empire under the Achaemenid dynasty in the 6th century BC. The ruins of Persepolis and Pasargadae, two of the four capitals of the Achaemenid Empire, are located in near Shiraz. Persepolis That UNESCO declared the citadel of Persepolis as a World Heritage Site in 1979 was the ceremonial capital of the Persian Empire during the Achaemenid dynasty and is situated 70 km northeast of modern Shiraz.

Iran is the eighteenth largest country in the world, with an area of 1,648,000 km2 (636,000 sq mi). Its area roughly equals that of the United Kingdom, France, Spain, and Germany combined, or slightly less than the US state of Alaska. Its borders are with Azerbaijan (432 km/268 mi) and Armenia (35 km/22 mi) to the north-west; the Caspian Sea to the north; Turkmenistan (992 km/616 mi) to the north-east; Pakistan (909 km/565 mi) and Afghanistan (936 km/582 mi) to the east; Turkey (499 km/310 mi) and Iraq (1,458 km/906 mi) to the west; and finally the waters of the Persian Gulf and the Gulf of Oman to the south.

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 plateaux from one another. The populous western part is the most mountainous, with ranges such as the Caucasus, Zagros and Alborz Mountains; the latter contains Iran's highest point, Mount Damavand at 5,610 m (18,405 ft), which is not only the country's highest peak but also the highest mountain on the Eurasian landmass west of the Hindu Kush.The Northern part of Iran is covered by dense rain forests called Shomal or the Jungles of Iran. The eastern part consists mostly of desert basins such as the Dasht-e Kavir, Iran's largest desert, in the north-central portion of the country, and the Dasht-e Lut, in the east, as well as some salt lakes. This is because the mountain ranges are too high for rain clouds to reach these regions. The only large plains are found along the coast of the Caspian Sea and at the northern end of the Persian Gulf, where Iran borders the mouth of the Shatt al-Arab (or the Arvand Rūd) river. Smaller, discontinuous plains are found along the remaining coast of the Persian Gulf, the Strait of Hormuz and the Sea of Oman.

Iran's climate ranges from arid or semiarid, to subtropical along the Caspian coast and the northern forests. On the northern edge of the country (the Caspian coastal plain) temperatures rarely fall below freezing and the area remains humid for the rest of the year. Summer temperatures rarely exceed 29 °C (85 °F).Annual precipitation is 680 mm (27 in) in the eastern part of the plain and more than 1,700 mm (67 in) in the western part. To the west, settlements in the Zagros basin experience lower temperatures, severe winters with below zero average daily temperatures and heavy snowfall. The eastern and central basins are arid, with less than 200 mm (eight in) of rain, and have occasional deserts. Average summer temperatures exceed 38 °C (100 °F). The coastal plains of the Persian Gulf and Gulf of Oman in southern Iran have mild winters, and very humid and hot summers. The annual precipitation ranges from 135 to 355 mm (five to fourteen inches).

Iran's wildlife is composed of several animal species including bears, gazelles, wild pigs, wolves, jackals, panthers, Eurasian lynx, and foxes. Domestic animals include, sheep, goats, cattle, horses, water buffalo, donkeys, and camels. The pheasant, partridge, stork, eagles and falcon are also native to Iran.

The political system of the Islamic Republic is based on the 1979 Constitution. The system comprises several intricately connected governing bodies. The Supreme Leader of Iran is responsible for delineation and supervision of the general policies of the Islamic Republic of Iran.The Supreme Leader is Commander-in-Chief of the armed forces, controls the military intelligence and security operations; and has sole power to declare war or peace.The heads of the judiciary, state radio and television networks, the commanders of the police and military forces and six of the twelve members of the Council of Guardians are appointed by the Supreme Leader.The Assembly of Experts elects and dismisses the Supreme Leader on the basis of qualifications and popular esteem.The Assembly of Experts is responsible for supervising the Supreme Leader in the performance of legal duties.

After the Supreme Leader, the Constitution defines the President of Iran as the highest state authority. The President is elected by universal suffrage for a term of four years and can only be re-elected for one term. Presidential candidates must be approved by the Council of Guardians prior to running in order to ensure their allegiance to the ideals of the Islamic revolution.The President is responsible for the implementation of the Constitution and for the exercise of executive powers, except for matters directly related to the Supreme Leader, who has the final say in all matters.The President appoints and supervises the Council of Ministers, coordinates government decisions, and selects government policies to be placed before the legislature. Eight Vice-Presidents serve under the President, as well as a cabinet of twenty two ministers, who must all be approved by the legislature.Unlike many other states, the executive branch in Iran does not control the armed forces. Although the President appoints the Ministers of Intelligence and Defense, it is customary for the President to obtain explicit approval from the Supreme Leader for these two ministers before presenting them to the legislature for a vote of confidence. Iran's current president, Mahmoud Ahmadinejad, was elected in a run-off poll in the 2005 presidential elections. His term expires in 2009.

As of 2008, the Legislature of Iran (also known as the Majlis of Iran) is a unicameral body. Before the Iranian Revolution, the legislature was bicameral, but the upper house was removed under the new constitution. The Majlis of Iran comprises 290 members elected for four-year terms. The Majlis drafts legislation, ratifies international treaties, and approves the national budget. All Majlis candidates and all legislation from the assembly must be approved by the Council of Guardians. The Council of Guardians comprises twelve jurists including six appointed by the Supreme Leader. The others are elected by the Parliament from among the jurists nominated by the Head of the Judiciary.

The Council interprets the constitution and may veto Parliament. If a law is deemed incompatible with the constitution or Sharia (Islamic law), it is referred back to Parliament for revision. In a controversial exercise of its authority, the Council has drawn upon a narrow interpretation of Iran's constitution to veto parliamentary candidates. The Expediency Council has the authority to mediate disputes between Parliament and the Council of Guardians, and serves as an advisory body to the Supreme Leader, making it one of the most powerful governing bodies in the country. The Supreme Leader appoints the head of Iran's Judiciary, who in turn appoints the head of the Supreme Court and the chief public prosecutor. There are several types of courts including public courts that deal with civil and criminal cases, and "revolutionary courts" which deal with certain categories of offenses, including crimes against national security. The decisions of the revolutionary courts are final and cannot be appealed. The Special Clerical Court handles crimes allegedly committed by clerics, although it has also taken on cases involving lay people. The Special Clerical Court functions independently of the regular judicial framework and is accountable only to the Supreme Leader. The Court's rulings are final and cannot be appealed. The Assembly of Experts, which meets for one week annually, comprises 86 "virtuous and learned" clerics elected by adult suffrage for eight-year terms. As with the presidential and parliamentary elections, the Council of Guardians determines candidates' eligibility. The Assembly elects the Supreme Leader and has the constitutional authority to remove the Supreme Leader from power at any time.

As all of their meetings and notes are strictly confidential, the Assembly has never been publicly known to challenge any of the Supreme Leader's decisions. Local City Councils are elected by public vote to four-year terms in all cities and villages of Iran. According to article seven of Iran's Constitution, these local councils together with the Parliament are "decision-making and administrative organs of the State". This section of the constitution was not implemented until 1999 when the first local council elections were held across the country. Councils have many different responsibilities including electing mayors, supervising the activities of municipalities; studying, planning, co-ordinating and implementing of social, cultural, educational, health, economic, and welfare requirements of their constituencies.

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. Its economic infrastructure has been improving steadily over the past two decades but continues to be affected by inflation and unemployment. In the early 21st century the service sector contributed the largest percentage of the GDP, followed by industry (mining and manufacturing) and agriculture. In 2006, about 45% of the government's budget came from oil and natural gas revenues, and 31% came from taxes and fees.

Government spending contributed to an average annual inflation rate of 14% in the period 2000–2004. Iran has earned $70 billion in foreign exchange reserves mostly from crude oil exports (80% as of 2007).In 2007, the GDP was estimated at $206 billion ($852 billion at PPP), or $3,160 per capita ($12,300 at PPP).Iran's official annual growth rate was at 6% (2008). Because of these figures and the country’s diversified but small industrial base, the United Nations classifies Iran's economy as semi-developed.

Close to 1.8% of national employment is generated in the tourism sector which is slated to increase to 10% in the next five years. About 1,659,000 foreign tourists visited Iran in 2004; most came from Asian countries, including the republics of Central Asia, while a small share came from the countries of the European Union and North America. Iran currently ranks 89th in tourist income, but is rated among the 10 most touristic countries in the world. Weak advertising, unstable regional conditions, a poor public image in some parts of the world, and absence of efficient planning schemes in the tourism sector have all hindered the growth of tourism.

The administration continues to follow the market reform plans of the previous one and indicated that it will diversify Iran's oil-reliant economy. Iran has also developed a biotechnology, nanotechnology, and pharmaceuticals industry. The strong oil market since 1996 helped ease financial pressures on Iran and allowed for Tehran's timely debt service payments. 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.

Over the past 15 years, the authorities have placed an emphasis on the local production of domestic-consumption oriented goods such as home appliances, cars, agricultural products, pharmaceutical, etc. Today, Iran possesses a good manufacturing industry, despite restrictions imposed by foreign countries. However, nationalized industries such as the bonyads have often been managed badly, making them ineffective and uncompetitive with years. Currently, the government is trying to privatize these industries, and, despite successes, there are still several problems to be overcome, such as the lagging corruption in the public sector and lack of competitiveness.

Iran has leading manufacture industry in the fields of car-manufacture and transportations, construction materials, home appliances, food and agricultural goods, armaments, pharmaceuticals, information technology, power and petrochemicals in the Middle East.

Iran is a diverse country consisting of people of many religions and ethnic backgrounds cemented by the Persian culture. The majority of the population speaks the Persian language, which is also the official language of the country, as well as other Iranian languages or dialects. Turkic languages and dialects (most importantly Azeri) are spoken in different areas in Iran. Additionally, Arabic is spoken in the southwestern parts of the country.

The main ethnic groups are Persians (51%), Azeris (24%), Gilaki and Mazandarani (8%), Kurds (7%), Arabs (3%), Baluchi (2%), Lurs (2%), Turkmens (2%), Laks, Qashqai, Armenians, Persian Jews, Georgians, Assyrians, Circassians, Tats, Mandaeans, Gypsies, Brahuis, Hazara, Kazakhs and others (1%).

Iran's population increased dramatically during the latter half of the 20th century, reaching about 72 million by 2008. In recent years, however, Iran's birth rate has dropped significantly. Studies project that Iran's rate of population growth will continue to slow until it stabilizes above 90 million by 2050.More than two-thirds of the population is under the age of 30, and the literacy rate is 77%.Women today compose more than half of the incoming classes for universities around the country and increasingly continue to play pivotal roles in society.

Iran hosts one of the largest refugee populations in the world, with more than one million refugees, mostly from Afghanistan and Iraq. Since 2006, Iranian officials have been working with the UNHCR and Afghan officials for their repatriation. According to estimates, between two and three million Iranian citizens have emigrated to other countries, mostly since the Iranian Revolution in 1979. Religion in Iran is dominated by the Twelver Shi'a branch of Islam, which is the official state religion and to which about 89% of Iranians belong. About 9% of Iranians belong to the Sunni branch of Islam, mainly Kurds and Iran's Balochi Sunni. The remaining 2% are non-Muslim religious minorities, including Bahá'ís, Mandeans, Hindus, Yezidis, Yarsanis, Zoroastrians, Jews, and Christians. The latter three minority religions are officially recognized and protected, and have reserved seats in the Majlis (Parliament).

However the Bahá'í Faith, Iran's largest religious minority, is not officially recognized, and has been persecuted during its existence in Iran. Since the 1979 revolution the persecution of Bahá'ís has increased with executions, the denial of civil rights and liberties, and the denial of access to higher education and employment. Iran does not recognize homosexuality. Iranian law considers male homosexuality a capital crime, while female homosexuality is considered a misdemeanor. However, Tran sexuality in Iran is legal if accompanied by a sex change operation. According to the Iranian Constitution, the government is required to provide every citizen of the country with access to social security that covers retirement, unemployment, old age, disability, accidents, calamities, health and medical treatment and care services. This is covered by public revenues and income derived from public contributions. The World Health Organization in the last report on health systems ranks Iran's performance on health level 58th, and its overall health system performance 93rd among the world's nations.

The Culture of Iran is a mix of ancient pre-Islamic culture and Islamic culture. Iranian culture probably originated in Central Asia and the Andronovo culture is strongly suggested as the predecessor of Iranian culture ca. 2000 BC. Iranian culture has long been a predominant culture of the Middle East and Central Asia, with Persian considered the language of intellectuals during much of the 2nd millennium, and the language of religion and the populace before that. The Sassanid era was an important and influential historical period in Iran as Iranian culture influenced China, India and Roman civilization considerably, and so influenced as far as Western Europe and Africa. This influence played a prominent role in the formation of both Asiatic and European art. This influence carried forward to the Islamic world. Much of what later became known as Islamic learning, such as philology, literature, jurisprudence, philosophy, medicine, architecture and the sciences were based on some of the practices taken from the Sassanid Persians to the broader Muslim world.

After Islamicization of Iran Islamic rituals have penetrated in the Iranian culture. The most noticeable one of them is commemoration of Husayn ibn Ali. Every year in Day of Ashura most of Iranians, including Armenians and Zoroastrians participate in mourning for the martyrs of battle of Karbala. Daily life in modern Iran is closely interwoven with Shia Islam and the country's art, literature, and architecture are an ever-present reminder of its deep national tradition and of a broader literary culture. The Iranian New Year (Nowruz) is an ancient tradition celebrated on 21 March to mark the beginning of spring in Iran. It is also celebrated in Afghanistan, Republic of Azerbaijan, Uzbekistan, Turkmenistan, Tajikistan, Kazakhstan and previously also in Georgia and Armenia. It is also celebrated by the Iraqi and Anatolian Kurds. Nowrouz was nominated as one of UNESCO's Masterpieces of the Oral and Intangible Heritage of Humanity in 2004. The cuisine of Iran is diverse, with each province featuring dishes, as well as culinary traditions and styles, distinct to their regions.

The main Persian cuisines are combinations of rice with meat, chicken or fish and some onion, vegetables, nuts, and herbs. Herbs are frequently used along with fruits such as plums, pomegranates, quince, prunes, apricots, and raisins. To achieve a balanced taste, characteristic flavorings such as saffron, dried limes, cinnamon, and parsley are mixed delicately and used in some special dishes. Onions and garlic are normally used in the preparation of the accompanying course, but are also served separately during meals, either in raw or pickled form. Iran is also famous for its caviar. Iranian food is not spicy. Iranian cinema has thrived in modern Iran, and many Iranian directors have garnered worldwide recognition for their work. Iranian movies have won over three hundred awards in the past twenty-five years. One of the best-known directors is Abbas Kiarostami. The media of Iran is a mixture of private and state-owned, but books and movies must be approved by the Ministry of Culture and Islamic Guidance before being released to the public. The Internet has become enormously popular among the Iranian youth. Iran is now the world's fourth largest country of bloggers.

With two thirds of Iran's population under the age of 25, sports, many sports are practiced in Iran, both traditional and modern. Iran is the birthplace of polo, and Varzesh-e Pahlavani. Freestyle wrestling has been traditionally regarded as Iran's national sport, however today, the most popular sport in Iran is football (soccer), with the national team having reached the World Cup Final Tournament three times, and having won the Asian Cup on three occasions. In 1974, Iran became the first country in the Middle East to host the Asian Games. Iran is home to several unique skiing resorts, with the Tochal resort being the world's fifth-highest ski resort (3,730 m/12,238 ft at its highest station), and located only fifteen minutes away from Tehran. Being a mountainous country, Iran is a venue for hiking, rock climbing, and mountain climbing. Iranian are also active in sports.

 

By 2000 literacy for all Iranians aged 15 and older had reached 76.9 %. The literacy rate was higher for males (83.7 %) than for females (70 %); the rate was also higher in cities than in rural areas. In the past two decades, the education system has been reformed several times. General education is free and compulsory from the age of six. It comprises 5 years of primary, 3 years of lower secondary, 3 years of upper secondary and one year of pre-university education. The language of instruction is Farsi. Iran has more than 30 tuition-free public universities and many other institutes of higher learning. These include medical universities and specialized colleges providing instruction in teacher training, agriculture, and other subjects. In addition to the public system, Iran has a private system of higher education that consists of theological colleges and the Islamic Free University, which has been developing campuses in cities throughout the country since its establishment in the late 1980s. The university is presently active in over 110 cities in Iran with more than half a million students. Presently, 54 universities and institutes of higher education are active under the Ministry of Science, Research and Technology.

In addition, the comprehensive Applied Sciences University was established in order to strengthen technical and vocational education. Some 33 private institutes of higher education, offering both undergraduate and postgraduate courses with about 23,000 students are active in Iran. Distance education is also available. Payam-e-Nour University aimed to expand higher education in remote areas for employed candidates, takes part in training of specialized manpower and makes efficient use of educational potentials and facilities. The university admitted students in 18 disciplines through nation-wide entrance examinations in 147 centers across the country. The number of students enrolled in all institutions in the academic year 1998-99 was 1,308,150 including 47.62% students in the public sector and 52.38% students in the private sector. The proportion of female students was 42.26% in the public sector and 44.46% in the private sector.

Medical care in Iran is limited and expensive. There are about 30,000 doctors in the country, mainly therapists and dentists, and about half of them work in the capital. There is a small number of hospitals with 1.5 beds per 1,000 people. Basic medical care and medicines are available in the principal cities of Iran, but they may not be available in outlying areas. When making a decision regarding health insurance, travellers should consider that many foreign doctors and hospitals require payment in cash prior to providing service. Uninsured travellers who require medical care overseas often face extreme difficulties.
