Estimate. UN DESA Population Division, World Population Prospects 2024: population by five-year age group and sex, Iran, mid-1990 and mid-2023 (2023 is the last WPP 2024 estimate year; later years are projections). The pyramid shows each age group as a share of all women (left) and of all men (right), as published by the World Bank's Health, Nutrition and Population Statistics (series SP.POP.0004.FE.5Y to SP.POP.80UP.MA.5Y, CC BY 4.0), read via the progrss vault (§4.11, wb-more-databases 15/0). Both-sexes counts in the takeaways are UN WPP 2024 annual population by five-year age group, read via the progrss vault (§4.11, un-wpp 3/0; licence CC BY 3.0 IGO stated by UN DESA): aged 35–39 in 2023, 9,156,119; aged 0–4 in 1990, 9,658,711 and in 2023, 6,201,275 (−35.8%); under 15, 25,746,781 in 1990 (44.1% of 58,380,092) and 20,693,926 in 2023 (22.8% of 90,608,707). Shares of the total are progrss calculations. The yellow bands, ages 30–44 in 2023, are the people born roughly 1979–1993; in 1990 they were children under 12, or not yet born. UN births peaked at about 2.1 million a year in 1984–86 (UN WPP 2024 live births), so calling them a baby boom is an Interpretation. Iran's last census was in 2016, so the 2023 figures are UN modelled estimates. Counts are of residents: they include migrants and refugees living in Iran and leave out Iranians abroad. No cause is claimed.
