Iceland Population Pyramid 2031
Iceland in 2031
By 2031, the population of Iceland is expected to reach 416,609. Ten years before, in 2021, the projected population is 372,644 — 11.8% lower.
The median age is projected at 39.5 years, with 25.3 children under 15 and 27.6 people aged 65 or over for every 100 people of working age (15–64). This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
