Summary

Ireland in 2100

By 2100, the population of Ireland is expected to reach 5,286,120. Ten years before, in 2090, the projected population is still 5,493,730 — a ten-year decline of 3.8%.

Half of the population would be younger than 50.9 years, with 12.7% children under 15 and 33.3% aged 65 or older. This is a constrictive pyramid — its base is narrower than its middle, the signature of sustained low birth rates and population ageing.
