For the first time since 1995 more people left the Republic of Ireland than moved there, according to new figures.
The Central Statistics Office says the number of emigrants from the South in the year to April is estimated to have grown by over 40%, from 45,300 to 65,100.
At the same time the number of immigrants continued to decline, falling from 83,800 to 57,300.
The CSO figures also reveal that of the 65,100 people who emigrated, east European nationals were the largest group, accounting for 30,100. Irish nationals were the second-largest group at 18,400. Immigration of all non-Irish people showed a decline with those from 12 EU states, Cyprus, Czech Republic, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia, Slovenia, Bulgaria and Romania, showing the biggest fall from 33,700 in April 2008 to 13,500 in April 2009 — a decline of 20,200.
