Iran’s population growth has slowed markedly since the 1960s, falling from 3.01 % in 1961 to a World Bank‑reported 1.29 % in 2025, which places the country 94th globally. The sharpest acceleration occurred in the early 1980s, when the annual increase peaked at 5.29 % in 1982, a reflection of post‑revolutionary demographic dynamics and high fertility rates. By contrast, the all‑time trough of 0.19 % in 1994 signalled the impact of aggressive family‑planning policies and rising urbanization. Over the 65‑year series, Iran’s growth rate now aligns closely with peers such as Djibouti (1.31 %) and Lao PDR (1.32 %), suggesting a transition toward the lower‑growth profile typical of many middle‑income economies. Continued declines in fertility, coupled with aging and migration trends, are likely to keep the growth rate modest, although any reversal in policy or a significant influx of migrants could alter the trajectory.
