Ireland Population Pyramid 2055
Ireland in 2055
By 2055, the population of Ireland is expected to reach 5,973,921. That would be 1.0% more than in 2045 (5,916,936).
Half of the population would be younger than 45.3 years, with 15.1% children under 15 and 27.0% aged 65 or older. The pyramid is constrictive: cohorts of children are smaller than those of their parents, reflecting low fertility and an ageing population.
