Iran’s population has experienced significant growth over the past several decades. In the mid-20th century, Iran’s population was around 17 million, but by 2024, it has surpassed 87 million people. The country saw rapid population growth during the 1980s, driven by high birth rates following the Islamic Revolution. However, in the 1990s and 2000s, government policies promoting family planning led to a sharp decline in fertility rates—from over 6 children per woman in the 1980s to below 2 in recent years. As a result, Iran’s population growth rate has slowed considerably, and the country is now facing challenges related to an aging population and a shrinking workforce, which may impact its economic and social development in the coming decades.
