Rapid immigration during the economic boom of the late 1990s and early 2000s means that Ireland now has one of the highest proportions of foreign-born residents in the EU. This report investigates residential patterns among Ireland’s migrant population. Where migrants live has an important influence on their integration prospects: some commentators argue that spatial concentration makes it difficult for migrants and minorities to achieve full social integration into the host society (Massey and Mullen, 1984). The report seeks to answer the following research questions: 1. How is the migrant population distributed around Ireland and in the major cities? 2. To what extent are migrants residentially segregated from the Irish and UK-born population? 3. Has there been change over time in the level of residential segregation? 4. How can the areas in which immigrants are concentrated be characterised in terms of deprivation/affluence and the housing stock
