Iranian refugees

Iran's population increased dramatically during the later half of the 20th century, reaching about 80 million by 2016. As of 2025, Iran's population is around 86.6 million. 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 stabilises above 100 million by 2050. Half of Iran's population was under 35 years old in 2012. As of January 2025, the average age of the Iranian population is 32 years.
