This chapter considers several issues related to EU enlargement, migration and Ireland's labour market. The first section presents the figures on net migration to Ireland for the recent past. What becomes clear from this picture, and what will be known
to most observers, is that the Irish experience since 2004 is broken up into two very distinct phases. For the four years after 2004, net migration was strong but from 2009, net migration has turned negative due to Ireland's deep recession. Given these
two phases, it is necessary to examine the labour market dimensions from different perspectives.
