Ireland Population Pyramid 2099
Ireland in 2099
United Nations projections (medium variant) put the population of Ireland at 5,309,954 in 2099. That would be 3.7% less than in 2089 (5,511,287).
Half of the population would be younger than 50.8 years, with 12.7% children under 15 and 33.2% aged 65 or older. The narrow base of the pyramid marks a constrictive age structure: fertility below replacement level and a rising share of older people.
