In 1800, the population of the modern-day territory of Iran was approximately 6.3 million. This figure would see modest growth throughout the 19th century, as several wars and a mass famine in 1870-1871 (modern estimates put its death toll at around 1.5 million people) were largely balanced out by a surge in migration to Iran; this migration came as the Russian Empire expanded into the Caucuses, and caused a wave of refugees to flee southwards to avoid forced expulsion and ethnic cleansing in the North Caucasus region, particularly from 1864 onwards. As a result, the population of Iran reached ten million by the turn of the 20th century.

Twentieth century growth Iran’s population would begin to grow rapidly in the 20th century, as the discovery of oil in the country in 1908 led to an economic boom, and the socio-economic reforms implemented under Reza Shah would see a number of medical and healthcare advancements across the country. Although unpopular with religious fundamentalists, Reza Shah's reforms had long-term influence on the demographic development of Iran, even after his abdication in 1941. Following the Second World War, Iran became increasingly westernized and developed relatively strong relations with the U.S.; however, western influence, economic imbalances and the oppression of the Mohammed Reza Shah's regime became the driving forces behind the Iranian Revolution, which was one of the most significant moments in the history of the region.

Growth after the Revolution The 1979 Iranian Revolution saw the removal of the Shah and an end to Iran's so called westernization; the monarchy was replaced by an Islamic, theocratic regime led by the Supreme Leader, Ayatollah Ruhollah Khomeini. During Khomeini's decade in charge he oversaw Iran's transition into an Islamic Republic, which implemented radical political and cultural changes in the country, and this coincided with an increased population growth rate in the 1980s. This growth was promoted by the Iranian government, who encouraged a baby boom during the Iran–Iraq War between 1980 and 1988, as part of an effort to increase future Iranian military manpower. As a result of this strategy, the population of Iran would grow from approximately 38.6 million in 1980 to over 56 million just a decade later. Following the implementation of a UN-brokered ceasefire in 1988, population growth in Iran would slow, as economic sanctions and government implementation of family planning policies would lead to a drop in fertility. Population growth has continued steadily into the 21st century, however, and in 2020, Iran is estimated to have a population of 84 million.

In 2020, around 98.5 percent of the Iranian population identified as Muslim. Around 81 percent identified as Shia Muslims in the same year, while a much smaller share followed the Sunni Muslim religion. In Iran, most Sunni Muslims belong to ethnic minority groups.

Iran’s demographics
The total population in Iran has grown steadily and is expected to surpass 90 million in 2028. The vast majority of the population in the country was between 15 and 64 years of age. At the same time, the share of people aged above 64 increased in recent years and constituted over seven percent of the total population.

Muslim population worldwide

In Europe, it was estimated that the Muslim population could triple by the middle of the century. In Southeast Asia, Indonesia had the largest share of Muslims as a proportion of its population. On the African continent, the highest number of Muslims was estimated in Nigeria, with close to a hundred million Islam followers. In the United States, less than one percent of the population identified as Muslims.

In 1925, the total fertility rate of Iran was just over seven children per woman, meaning that the average woman in Iran could expect to have seven children over the course of their reproductive years. The fertility rate would see little change from this figure until the late 1960s, when modernization and significant decreases in child mortality would lead the fertility rate to fall to just over 6.2 in 1975. However, fertility would begin to rise again in the 1980s, as the modernization policies of the Shah would be replaced by Islamic economic and social platforms with the 1979 Islamic Revolution in the country. The total fertility rate in the country would peak at just over 6.5 children per woman in 1985, in response to strong encouragement by the Iranian government promoting larger families to improve Iran’s manpower advantage over Iraq in the 1980-1988 Iraq-Iran War. Following the war’s end with a UN-brokered ceasefire in 1988, fertility would fall sharply in the country, falling to 2.4 by the turn of the century, and falling below replacement-level in 2005. However, after bottoming out at 1.82 in 2010, fertility has risen somewhat in recent years, as the Iranian government has rolled out a series of economic incentives aimed at increasing fertility in the country. As a result, in 2020, the total fertility rate in Iran is estimated to have risen slightly, to 2.15 children per woman, above replacement-level.

During the presidential election of 2024 in Iran, It is estimated that the voter turnout rate was about 40 percent. The 2024 presidential election was a snap election, to select the successor of president Seyyed Ebrahim Raisi, after he passed away during a helicopter crash in May 2024, together with the foreign minister and several other Iranian officials.

This statistic depicts the number of eligible and actual voters for the presidential elections in the Islamic Republic of Iran from 1980 to 2021. During the presidential election of 2021, the number of eligible voters was 59.3 million but only 28.9 million voters actually cast their vote.

In 1800, the region of present-day Iraq had an estimated population of just over one million people. The population of Iraq would grow slowly throughout the 19th century, reaching just over two million by the beginning of the 20th century. However, Iraq’s population would begin to rise rapidly in the 1920s, as modernization programs implemented by the British administration, aided by the discovery of oil in 1927, would see mortality rates fall and living standards rise for much of the country. As a result, Iraq would grow to have a population of just under seven million by the time of the Iraqi Republic's establishment in 1958. Population growth would continue to increase following the creation of the republic, doubling to fourteen million by the 1980s; according to these estimates, the Iran-Iraq War of the 1980s did little to change the trajectory of Iraq's population growth, nor did the Gulf War of 1990-1991, despite Iraq suffering up to half a million fatalities in these conflicts. Iraq's population growth did slow in the early 2000s however, with the U.S.-led invasion of Iraq in 2003. While the initial invasion would see relatively few casualties (compared to previous conflicts), the resulting economic turmoil and political instability, combined with the rise of the Iraqi insurgency and civil war in the region, would cause population growth to slow for several years. Population growth would recover starting in the 2010s, and by 2020, Iraq is estimated to have a population of just over forty million.

In 1870, life expectancy from birth in the modern-day territory of Iran was approximately 25.6 years. This figure would see little change in Iran for much of the late 19th and early 20th century; the only major change was the dip in the late 1910s, resulting from the 1918 Spanish Flu epidemic) and a famine from 1918 to 1919, which led to significant fatalities across the region. Life expectancy would begin to grow rapidly in the 1940s, as the country’s oil reserves, discovered in 1908, would see an economic boom in the years during and immediately following the Second World War, providing a valuable source of funding for socio-economic reforms implemented under Reza Shah. This, in turn, saw a rapid modernization of healthcare in the country, as well as the implementation of mass vaccination programs in the early 1940s, which greatly lowered child mortality rates and allowed life expectancy to rise.

As implementation of these programs would continue, life expectancy from birth rose from just over 27 years in 1940, to approximately 39 years in 1950. After the end of the rapid growth of the 1940s, life expectancy would continue steadily rise until 1980, peaking at 56.7 years. However, life expectancy would fall to just 52 years in 1985, the result of mass fatalities in the Iran-Iraq War of 1980 to 1988. Following the war’s end with a UN-brokered ceasefire in 1988, life expectancy would quickly recover, reaching over 69 years by the turn of the century. Life expectancy has continued to rise throughout the 21st century, and it is now estimated that the average child born in Iran in 2020 will live to the age of approximately 76 years.
