Indicator history

The most recent report on population, the Preliminary Report from the 2011 Census, does not separate the data into population by nationality or ethnicity.  The Central Statistics Office did however release a report in 2008 on Non-Irish Nationals Living in Ireland based on the data from the 2006 Census.  That report lists 414,512 non-Irish nationals living in the state.

The official introduction to the report describes the methodology: "This report presents a thematic examination of the non-Irish national population living in Ireland at the time of the 2006 Census. The information in the report is sourced entirely from the census and deals with persons who were usually resident in Ireland in April 2006. While the Irish census is conducted on a de-facto basis (all persons present in the country on census night were enumerated) this report only deals with persons who were resident in Ireland at the time. Overseas visitors are excluded from the analysis. Non-Irish nationals were identified by their responses to the question ‘What is your nationality?’ This question was first asked in the 2002 Census, and while there is some limited scope for retrospective analysis the report primarily focuses on data taken from the 2006 Census."
