Then, according to the statistics, the drastic increase made the population reach 50 million in 1985. After increasing to 60 in 1995, it grew straight up to 70 million in 2005. The population statistics graph shows how dramatically the population had been increasing from year to year, and now the population of Iran is over 78 million.

The major part (89%) of the population in Iran is Shi'a Muslim, 10% is Sunni Muslim, and the remaining 1% are Christian, Zorastrian, Baha’i and Jewish. Judaism has a very long history in the country, although the Revolution and the establishment of Israel has left just under 9,000 Jews in the country. Christians are the largest minority religion at 250,000 to 370,000. Most Christians have an Armenian origin.

Iran has one of the largest refugee populations in the world, containing more than one million refugees, mostly from Iraq and Afghanistan. Iran also has a sizeable diaspora as over 5 million Iranians emigrated to other countries following the 1979 Iranian Revolution.

Languages used in Iran include: Persian (official), Azeri Turkic and Turkic dialects, Kurdish, Gilaki and Mazandarani, Luri, Balochi, Arabic, and other languges.

Iran Population Growth

The population of Iran is increasing at an alarming rate. This is also due to the people migrating from the surrounding countries (Afghanistan and Iraq) for security reasons. The population of Iran changed and increased drastically during the past years, but now it is expected to drop by 2101 according to the deputy health minister of Iran, Fatima Rakhshani.

Iran's young population is expected to reach 14 percent of the total population in 2050.
