2023 population pyramid
This is the population pyramid for Iran. A population pyramid illustrates the age and sex structure of a country's population and may provide insights about political and social stability, as well as economic development. The population is distributed along the horizontal axis, with males shown on the left and females on the right. The male and female populations are broken down into 5-year age groups represented as horizontal bars along the vertical axis, with the youngest age groups at the bottom and the oldest at the top. The shape of the population pyramid gradually evolves over time based on fertility, mortality, and international migration trends.

Known as Persia until 1935, Iran became an Islamic republic in 1979 after the ruling monarchy was overthrown and Shah Mohammad Reza PAHLAVI was forced into exile. Conservative clerical forces led by Ayatollah Ruhollah KHOMEINI established a theocratic system of government with ultimate political authority vested in a religious scholar referred to commonly as the Supreme Leader who, according to the constitution, is accountable only to the Assembly of Experts - a popularly elected 88-member body of clerics. US-Iran relations became strained when a group of Iranian students seized the US Embassy in Tehran in November 1979 and held embassy personnel hostage until mid-January 1981. The US cut off diplomatic relations with Iran in April 1980. During the period 1980-88, Iran fought a bloody, indecisive war with Iraq that eventually expanded into the Persian Gulf and led to clashes between US Navy and Iranian military forces. Iran has been designated a state sponsor of terrorism since 1984. Iran continues to be subject to a range of international sanctions and export controls because of its continued involvement in terrorism, weapons proliferation, human rights abuses, and concerns over the nature of its nuclear program. Iran received nuclear-related sanctions relief in exchange for its nuclear concessions under the Joint Comprehensive Plan of Action's (JCPOA) Implementation Day beginning in January 2016. However, the US re-imposed nuclear-related sanctions on Iran after it unilaterally terminated its participation in the JCPOA in May 2018. In October 2023, the EU and the UK also decided to maintain nuclear proliferation-related measures on Iran, as well as arms and missile embargoes, in direct response to Iran's non-compliance with its JCPOA commitments following the US decision to terminate its participation in the accord.

Following the election of reformer Hojjat ol-Eslam Mohammad KHATAMI as president in 1997 and a reformist Majles (legislature) in 2000, a campaign to foster political reform in response to popular dissatisfaction was initiated. The movement floundered as conservative politicians, supported by the Supreme Leader, unelected institutions of authority like the Guardians Council, and the security services reversed and blocked reform measures while increasing repression. Starting with nationwide municipal elections in 2003 and continuing through Majles elections in 2004, conservatives reestablished control over Iran's elected government institutions, which culminated with the August 2005 inauguration of hardliner Mahmud AHMADI-NEJAD as president. His controversial reelection in June 2009 sparked nationwide protests over allegations of electoral fraud, which persisted until early 2011. President AHMADI-NEJAD's independent streak angered regime establishment figures, including the Supreme Leader, leading to conservative opposition to his agenda for the last year of his presidency, and an alienation of his political supporters. In June 2013, Iranians elected a centrist cleric Dr. Hasan Fereidun RUHANI to the presidency. A longtime senior member in the regime, he made promises of reforming society and Iran's foreign policy. In July 2015, Iran and the five UNSC permanent members, plus Germany (P5+1) finalized the JCPOA under which Iran agreed to restrictions on its nuclear program in exchange for nuclear-related sanctions relief; however, the US reimposed nuclear-related sanctions in 2018 dealing a blow to RUHANI's legacy and the Iranian economy. In November 2019, Tehran's decision to increase the price of gasoline overnight sparked nationwide protests, which the regime violently suppressed within a week. Conservatives won the majority of seats in Iranian Majles elections in elections in February 2020 and hardline cleric Ebrahim RAISI - who had a decades-long career in Iran's judiciary - was elected president in June 2021, resulting in a hardline and conservative monopoly across the regime's elected and unelected institutions.

As president, RAISI has concentrated on deepening Iran's foreign relations with anti-US states - particularly China and Russia - to weather US sanctions and diplomatic pressure, while supporting negotiations to restore a nuclear deal that began in 2021. RAISI contended with nationwide protests that began in September 2022 and persisted for over three months following the death of a Kurdish Iranian woman, Mahsa AMINI, while she was in morality police custody. Young people and women led the protests and demands focused on regime change rather than reform within the system or the redressal of economic grievances.

Telecommunication systems

general assessment: Iran’s telecom infrastructure has suffered from sanctions in recent years, which prevented the import of equipment and devices and encouraged widespread smuggling, with a consequent loss of tax revenue; to address this, the government introduced a device registration scheme, and bolstered the capacity for domestically manufactured mobile phones; companies have invested in broadening the reach of their LTE networks, which has increased network capacity and improved the quality of mobile broadband services; the country is also looking to 5G; the sector is still limited by low frequency bands; the government is addressing this with plans to reallocate the 3.5GHz band for 5G use; Iran is keen to grow its digital economy; Iran offers significant opportunities for growth in the telecoms sector; the country has one of the largest populations in the Middle East, and there is a high proportion of youthful, tech savvy users having considerable demand for both fixed and mobile telecom services; companies are offering national roaming to improve services in rural areas (2022)

Trafficking in persons

tier rating:

Tier 3 — Iran does not fully meet the minimum standards for the elimination of trafficking and is not making significant efforts to do so, therefore, Iran remained on Tier 3; the government took some steps that may prevent trafficking of some vulnerable populations, including providing access to schools, basic services, and temporary immigration relief for some Afghan children and adult refugees or migrants who registered for the government’s headcount initiative; however, the government continued a policy or pattern of employing or recruiting child soldiers and facilitating human trafficking; officials continued to perpetrate and condone trafficking crimes with impunity, both in Iran and overseas; the government did not report law enforcement efforts to address trafficking, and it brought spurious charges against LGBTQI+ activists; officials did not report investigating, prosecuting, or convicting officials complicit in the recruiting and use of child soldiers coerced to fight for Iranian-led militias in Syria; the government forced or coerced children to join Iranian security and anti-riot forces to suppress ongoing political protests, and coerced former Afghan Special Forces members to fight for Iranian-backed militia in Yemen; authorities failed to identify and protect trafficking victims among vulnerable populations and continued to deport or detain Afghan adults and children without screening for trafficking indicators (2023)

trafficking profile: human traffickers exploit domestic and foreign victims in Iran, and Iranians are exploited abroad; the continuing decline of the Iranian economy has significantly exacerbated human trafficking, particularly for vulnerable and marginalized groups such as ethnic minorities, refugees and migrants, LGBTQI+ persons, women, and children; Iranian and some foreign women and girls, as well as some men and LGBTQI+ persons, are highly vulnerable to sex trafficking in Iran; although commercial sex is illegal, the government reportedly condones and sometimes directly facilitates commercial sexual exploitation and sex trafficking of adults and children, which are endemic throughout the country; Iranian, Iraqi, Saudi, Bahraini, and Lebanese women are highly vulnerable to sex trafficking in large urban centers; Iranian women, boys, and girls are vulnerable to sex trafficking in Afghanistan, Armenia, Georgia, Iraq, Pakistan, Turkey, and the United Arab Emirates; Iranian and Afghan refugee and migrant children, orphans, and homeless children are highly vulnerable to forced labor in Iran; criminal groups reportedly play a significant role in human trafficking in Iran, including kidnapping or purchasing Iranian and migrant—especially Afghan—children for forced labor and sexual exploitation; foreign workers, including Pakistani migrants and Afghans, are highly vulnerable to abuse and forced labor in Iran; Iranian authorities continue to force and coerce Afghans, including children, as well as Pakistani migrants, Syrian nationals, and Iranian children, into armed groups to fight in Iraq, Syria, and Yemen or serve in Iran in paramilitary forces (2023)

the Islamic Revolutionary Guard Corps (IRGC) was formed in May 1979 in the immediate aftermath of Shah Mohammad Reza PAHLAVI’s fall, as leftists, nationalists, and Islamists jockeyed for power; while the interim prime minister controlled the government and state institutions, such as the Army, followers of Ayatollah Ruhollah KHOMEINI organized counterweights, including the IRGC, to protect the Islamic revolution; the IRGC’s command structure bypassed the elected president and went directly to KHOMEINI; the IRGC played a critical role in helping KHOMEINI consolidate power in the aftermath of the 1979 revolution, and it ensured that KHOMEINI's Islamic revolutionary vision prevailed against domestic challenges from nationalists and leftist factions in the scramble for control after the Shah's departure; the Iran-Iraq War (1980–88) transformed the IRGC into more of a conventional fighting force with its own ground, air, naval, and special forces, plus control over Iran’s strategic missile and rocket forces; today, the IRGC is a highly institutionalized and parallel military force to Iran’s regular armed forces (Artesh); it is heavily involved in internal security and has significant influence in the political and economic spheres of Iranian society, as well as Iran’s foreign policy; on the economic front, it owns factories and corporations and subsidiaries in banking, infrastructure, housing, airlines, tourism and other sectors; its special operations forces, known as the Qods/Quds Force, specialize in foreign missions and have provided advice, funding, guidance, material support, training, and weapons to militants in countries such as Afghanistan, Iraq, Syria, and Yemen, as well as extremist groups, including HAMAS, Hizballah, Kata’ib Hizballah, and Palestine Islamic Jihad (see Appendix T for additional details on the IRGC and Qods Force); the Qods Force also conducts intelligence and reconnaissance operations 

the Supreme Council for National Security (SCNS) is the senior-most body for formulating Iran’s foreign and security policy; it is formally chaired by the president, who also appoints the SCNS secretary; its members include the speaker of the Majles, the head of the judiciary, the chief of the Armed Forces General Staff (chief of defense or CHOD), the commanders of the Artesh (regular forces) and IRGC, and the ministers of defense, foreign affairs, interior, and intelligence; the SCNS reports to the supreme leader; the supreme leader is the commander-in-chief of the armed forces

the Iranian Armed Forces are divided between the regular forces (Artesh) and the IRGC; the Artesh primarily focuses on defending Iran’s borders and territorial waters from external threats, while the IRGC has a broader mission to defend the Iranian revolution from any foreign or domestic threat; in 1989, Iran established the Armed Forces General Staff to coordinate military action across both the Artesh and the IRGC; Iran also has a joint military headquarters, the Khatam ol-Anbia Central Headquarters, to command the Artesh and IRGC in wartime

the Artesh Ground Force consists of about 50 combat brigades, mostly infantry with a sizable contingent of airborne, armored, commando, mechanized, and special operations forces; most units are concentrated along the Iran-Iraq border, reflecting the force’s primary mission to defend against foreign invasion; the IRGC Ground Force is organized into corps for each of the 31 provinces and Tehran city; the corps have a broad mix of armored, infantry, mechanized, and commando units and are postured to counter internal unrest or a ground invasion; the IRGC’s special operations forces are known as the Qods Force; the IRGC controls the Basij Paramilitary Forces, which are also organized into provincial corps with mobile/rapid-reaction, security, infantry, and commando battalions

the Artesh Navy is considered Iran’s “blue water” navy and has the primary mission of defending Iranian territorial waters and protecting the country’s economic interests in the Caspian Sea, Gulf of Oman, and beyond; it has approximately 10 frigates and corvettes, plus a small force of attack and midget submarines (note - Iran is the only Persian Gulf nation with a submarine force); the IRGC Navy is tasked with protecting primarily the Iranian littoral waters in the Persian Gulf and Strait of Hormuz and employs a force of mostly small, fast attack vessels armed with a variety of weapons systems including anti-ship missiles 

Iran’s air and air defense capabilities are split primarily across three services: the Islamic Republic of Iran Air Force (IRIAF) and the Islamic Republic of Iran Air Defense Force (IRIADF), both under the Artesh, and the IRGC Aerospace Force (IRGCASF); the IRIAF operates the majority of Iran’s combat aircraft and has more than 200 such aircraft, a considerable portion of which are older US models acquired before the 1979 revolution; the remainder includes older Chinese-, French-, and Russian-produced aircraft; the IRIADF controls the country’s surface-to-air missile capabilities; the IRGCASF operates some ground attack aircraft and most of Iran’s unmanned aerial vehicles; it also controls Iran’s cruise and ballistic missile force (2023)

Military and security service personnel strengths

information varies; up to 600,000 active armed forces personnel; approximately 400,000 Islamic Republic of Iran Regular Forces (350,000 Ground Forces; 18,000 Navy; 40,000 Air Force/Air Defense Forces); approximately 150-190,000 Islamic Revolutionary Guard Corps (100-150,000 Ground Forces; 20,000 Navy; 15,000 Aerospace Force; 5-15,000 Qods Force); estimated 90,000 active Basij Paramilitary Forces (2023)

Military equipment inventories and acquisitions

the Iranian military's inventory includes a mix of domestically produced and mostly older foreign equipment largely of Chinese, Russian, Soviet, and US origin (US equipment acquired prior to the Islamic Revolution in 1979); it also has some military equipment from North Korea, including midget submarines and ballistic missiles; in recent years, Iran has received some newer equipment from Russia; Iran has a defense industry with the capacity to develop, produce, support, and sustain air, land, missile, and naval weapons programs (2023)
