A BSTRACT Despite the emergence of a 'Europe of the regions', changes in the territorial governance arrangements of various countries, and the more pro-EU stance of regionalist parties, studies of citizens' attitudes towards the EU tend to focus on the member state level and neglect to examine patterns and determinants of opinion amongst sub-state regions.
Reflecting its distinct political and social context, this paper provides a detailed examination of the attitudes of the Northern Ireland electorate towards the EU. It uses time series evidence to track long-term shifts in public opinion over time. It then compares contemporary support and opposition for the integration process in Northern Ireland, England, Scotland and Wales. Finally, it uses linear regression estimation to examine which individual-level factors affect attitudes towards the integration process in NorthernIreland. The evidence shows that attitudes have become steadily more pro-EU over time and that opinion in Northern Ireland is more favourable compared to attitudes in England, Scotland and Wales. Results from a multivariate analysis show that level of education, religious status, party support and national economic appraisals contribute to attitudes towards the integration process.
