Northern Ireland Loyalty Study, 1968 (ICPSR 7237)

Principal Investigator(s): Rose, Richard, University of Strathclyde-Glasgow


This study focused on religious and political issues in Northern Ireland. Catholic and Protestant relations were explored in terms of past differences, political party affiliations, discrimination, and intermarriage. Respondents were queried about the border and its effect on Northern Ireland, the constitutional position of their country, support for the government, the major political parties, and what they represented. Social class consciousness was probed in questions asking the respondents to describe members of various classes, to evaluate the problems of class conflict within the country, and to place themselves within the social class structure. Respondents' activities in clubs and organizations, extent of family ties, loyalty to their community, and their exposure to local and national news media were also explored. Demographic data include sex, age, religion, marital status, number of children, and occupation. A single questionnaire was administered to Protestants and Catholics, and only a small number of questions was asked of only one group or the other. Filtering for religion allows analysis of each group alone. The study contains several derived variables.
