Regional Development Monitor (RDM) Update – Population Estimates, Age Cohorts and Dependency Rates
Description: The RDM has been updated with the latest population estimates from the CSO for 2025 (total population, age cohorts and dependency rates).
Each year the CSO publishes annual estimates of population with figures on total population (at State and NUTS 3 level), age cohorts (5 year age cohorts), net migration (immigration less emigration) and the natural increase of the population (births minus deaths).
Summary of Latest Results:
 • In the 12 months to the end of April 2025 the population in Ireland rose by 78,300 (+1.45%) people and now stands at 5,458,600 people.
 • There were 125,300 immigrants in the 12-months to April 2025, which is a 16% decrease from the same period of 2024. This was the fourth successive 12-month period where over 100,000 people immigrated to Ireland.
 • Of those immigrants, 31,500 were returning Irish citizens, 25,300 were other EU citizens, and 4,900 were UK citizens. The remaining 63,600 immigrants were citizens of other countries.
 • There was a fall in emigration numbers for the first time since 2020 with 65,600 people departing the State in the 12 months to April 2025. This was a decrease of 4,300 people, or 6.2%, compared with 69,900 in the same period of 2024.
 • There was a natural increase of 18,600 people in the State, comprised of 54,400 births and 35,800 deaths.
