Size: Land area of about 1,648,000 square kilometers; sovereignty claimed over territorial waters up to 12 nautical miles.

Population: Preliminary results of October 1986 census listed total population as 48,181,463, including approximately 2.6 million refugees from Afghanistan and Iraq. Population grew at rate of 3.6 percent per annum between 1976 and 1986. Government figures showed 50 percent of population under fifteen years of age in 1986.

Education: School system consists of five years of primary (begun at seven years of age), three years of middle school, and four years of high school education. High school has three cycles: academic, science and mathematics, and vocational technical. Government announced 11.5 million students in above school system in academic year 1986-87; percentage of school age population in school not published. Postrevolution decrease in university enrollments, particularly percentage of women students, which declined from 40 percent in prerevolutionary period to 10 percent in 1984. Number of students abroad also declined.

Health: Iranian Medical Association reported 12,300 doctors in 1986; 38,000 additional doctors needed to provide population with minimally adequate health care. Most medical personnel located in large cities. High infant mortality rate. Gastrointestinal, parasitic, and respiratory diseases other chief causes of mortality.

Languages: Persian official language and native tongue of over half the population. Spoken as a second language by majority of the remainder. Other Indo-European languages, such as Kirmanji (the collective term in Iran for the dialects spoken by Kurds), as well as Turkic languages and Arabic also important.

Gross Domestic Product: About US$168 billion in 1985, US$165 billion in 1986, and US$176 billion (estimated) in 1987 (figure given at official rate; unofficial rate as much as 10 times higher for United States dollar value of rial). Percentage of GDP growth 1.5 percent (real) in 1985 and 10 percent (estimated) in 1986. Inflation rate estimated at 20 percent in 1985, 30 percent in 1986, and 35 percent in 1987. Figures must be regarded with caution as official sources seriously underestimate rate of inflation and currency depreciation.

Gross National Product: 1986 estimate US$82.4 billion.

Industry: Oil major industry. In 1986 oil production averaged 1.9 million barrels per day; in January 1987 crude oil production averaged 2.2 million barrels per day, of which exports averaged between 1.5 million and 1.7 million barrels per day. Reported reserves of 48.5 billion barrels in 1986 ranked Iran fourth behind Saudi Arabia, Soviet Union, and Kuwait. Damage to Iranian oil installations during 1986-87 reduced oil production and exports substantially. Natural gas reserves claimed by government to be 13.8 trillion cubic meters in 1987. Oil and gas produced estimated 8 percent of GDP in FY 1986-87. Non-oil industry mainly agricultural products, carpets, textiles, and war-related manufacturing such as munitions. Industry employed approximately 31 percent of work force in 1987. Manufacturing and mining produced estimated 23 percent of GDP in FY 1986-87. Services produced estimated 48 percent of GDP in FY 1986-87.

Agriculture: Accounted for estimated 21 percent of GDP in FY 1986- 87 and employed approximately 38 percent of work force. Despite regime efforts to promote self-sufficiency, Iran more dependent on agricultural imports in 1987 than in 1970s. Lack of progress resulted from unresolved land reform issues, poor cultivation practices, lack of farm labor because of military service, and migration to cities.

Imports: In 1983-84 about US$18.1 billion. Principal imports: road vehicles and machines (35 percent), manufactures and iron and steel (29 percent), and food and live animals (13 percent).

Exports: In 1985 about US$13.4 billion, of which all but about US$270 million from oil and gas. Oil exports in FY 1986-87 estimated between US$10.5 billion and US$11.5 billion; about US$900 million non-oil exports.

Roads: In 1984 a total of 136,381 kilometers of roads, of which 41 percent paved; of paved roads 16,551 kilometers of main roads and 34,838 kilometers of secondary roads.

Railroads: About 4,700 kilometers of railroads in 1987, including newly electrified track in north between Tabriz and Jolfa for Soviet imports; also rail connection with Turkey.

Pipelines: About 5,900 kilometers for crude oil; 3,900 kilometers for refined products; 3,300 kilometers for natural gas in 1987; some possibly inoperable as result of war damage.

Navy had fifteen combat vessels and thirty naval aircraft in 1986; by late 1987 only some small patrol craft and a few Hovercraft believed operable; three marine battalions; naval air had about thirty aircraft, mainly helicopters. Air force consisted of eight fighter and fighter-bomber squadrons, one reconnaissance squadron, two joint tanker-transport squadrons, five light transport squadrons, and five SAM squadrons; about ninety operational aircraft in 1986. Pasdaran had possibly eight divisions loosely organized in eleven regional commands and numerous independent brigades.

Paramilitary: Basij "Popular Mobilization Army" volunteers--strength varied; in 1986 said to be 3 million.
