Attitudes towards immigration in Ireland are the focus of this study and, more specifically, what aspects of life the native-born population perceive to be impacted by immigration into Ireland in 2018. This thesis uses two primary socioeconomic attributes of the native-born respondents as explanatory variables, focusing on education and income levels of the native-born population. The aim of this study is to examine the association between attitudes towards immigration, across different attitudinal dimensions, and socioeconomic status of native-born individuals in the Republic of Ireland in 2018. This thesis uses data taken from round 9 of the European Social Survey and purports that individuals (i) without tertiary education and (ii) on low-incomes will be more likely to oppose immigration across all dimensions of attitudes to immigration, all else equal. In addition, it propagates the idea that individuals will be more likely to oppose immigration due to the perceived effect of immigration on the economy, all else being equal.  This research draws on Group threat theory and Contact theory as the foundation for the hypotheses and research questions and enables investigation into the primary socioeconomic determinants influencing attitudes towards immigration in Ireland. Furthermore, whether an association exists between socioeconomic status and attitudes across all attitudinal dimensions is explored.  The results indicate that, all else equal, those who studied to at least a tertiary level are more likely to display positive attitudes towards immigration than those without a tertiary education, regardless of attitudinal dimension. Similarly, those on the highest incomes are more likely to exhibit positive attitudes to immigration across all dimensions compared to their low-income counterparts, all else being equal. Interestingly however, this thesis did not find statistically significant evidence that individuals will be more likely to oppose immigration due to the perceived impact of immigration on the economy, as was originally hypothesised.
