Compare Iran with another country

Where it stands

In 2025 Iran has 92,417,681 people, which is 1.13% of the 8.19 billion counted across the 217 countries and areas on this site. That puts it 17th by population, behind Viet Nam and ahead of Türkiye.

Since 1960

In 1960 the figure was 21,470,434. Since then the population has grown 4.3×, an average of 2.27% a year upward. It doubled at some point along the way — the year it first reached 42,940,868 was 1982.

The projection keeps rising to the end of the data: 101,861,993 in 2050, 10.2% above 2025. The highest figure on this page is that last one, so no peak has been reached yet.

The ranking in 2050

In 2050 the projected rank is 18th, down 1 place from 17th. Rankings move when other countries grow faster or slower, not only when Iran changes.

People and land

Iran covers 1,622,500 km² of land, so 2025 density is 57 people per km² — 148th most crowded of 216 places with an area figure. At that density a square 10 km on a side holds about 5,696 people.

The fertility rate was 1.68 births per woman in 2024, below the roughly 2.1 needed to keep a population steady without migration; life expectancy at birth was 77.9 years (2024); 22% of people were under 15 and 8.6% were 65 or older (2025); 77% of the population lived in cities. These shape the curve above: a young population keeps growing after fertility falls, an old one starts shrinking sooner.

Its nearest neighbours in the ranking are Viet Nam just above, with 102 million (1.1× as many), and Türkiye just below, with 85.9 million (1.08× as many as Türkiye has).
