In the year prior to April 2012 (FY 2012), an inflow of 53 000 was offset by an estimated outflow of over 87 000, resulting in net emigration of 34 000, the highest level for over two decades. Returning Irish nationals were the single largest constituent of immigration. Immigration from the EU New Member States (NMS) fell to about 10 000 in 2011 and 2012. Emigration of Irish nationals increased sharply to over 46 000 in FY 2012, over half of total emigration. Citizens of the NMS accounted for about 17% of all outflows, a substantial reduction from recent years.
