Demographic profile

Iran is the 17th most populous of the 238 countries and territories tracked on this site, home to about 1.12% of everyone alive. Within Southern and Central Asia, it ranks 4 of 13.

Each day brings roughly 3,497 births and 1,327 deaths, adding about 792,576 people over a year. At the current natural-increase rate of 0.85% annually, the population would double in roughly 82 years if the rate held. Real trajectories bend as fertility, mortality and migration shift, which is why the chart below shows both history and projection.

Among its first-level divisions, the largest by our modelled allocation is Lorestan, holding an estimated 19.7% of the national population. The full breakdown of all 31 states and regions is in the table below — regional figures outside Sudan are modelled estimates built on real region names, and are flagged as such.

Literacy stands near 88.7% and adult smoking prevalence around 13.6%, with life expectancy at about 69.7 years. Baselines come from UN World Population Prospects, the World Bank, WHO surveys, WorldPop and HDX; the counters project them forward in real time — the method, and every caveat, is documented on our data sources page.
