According to statistics released by the Central Statistics Office (CSO), approximately 42,000 of those arriving to live in the State in the 12 months leading up to April 2023 were Ukrainians fleeing the conflict.
29,600 of the 141,600 immigrants were relocating Irish citizens, 26,100 were people from other EU countries, and 4,800 were British nationals.
Over half of the remaining 81,100 people were residents of other nations, including Ukrainians.
It was the highest rate since April 2007 and the second year in a row that immigration numbers exceeded 100,000.
In terms of emigration, over 64,000 people left Ireland in the 12 months leading up to April 2023, up from 56,100 during the same time period in the previous year.
It was one of the highest numbers in recent years, according to the CSO.
To reach almost 5.3 million, the population increased by 97,600, the biggest 12-month increase since 2008.
In addition to the 77,600 net immigrants, there were 20,000 more people born naturally over the course of a year, with 55,500 births and 35,500 deaths.
Cathal Doherty, a statistician at the CSO who specialises in population estimates and projections said: “The population of Ireland was estimated to be 5.28 million, increasing by 97,600 people in the year leading up to April 2023.”
Since 2008, when the population increased by 109,200, “this was the largest 12-month population increase.”
