Iran's population grew rapidly during the latter half of the 20th century, increasing from about 19 million in 1956 to more than 84 million by July 2020. However, Iran's fertility rate has dropped significantly in recent years, coming down from a fertility rate of 6.5 per woman to  just a little more than 2 two decades later, leading to a population growth rate of about 1.39% as of 2018. Due to its young population, studies project that the growth will continue to slow until it stabilizes around 105 million by 2050.
