The purpose of this survey was to ascertain answers to such questions as whether societies are becoming more or less equal, whether they are expanding or restricting opportunity for their citizens and whether they are offering the kinds of education that will enable nations to cope with the challenges of technological change. The aim was to study the trends, correlates and determinants of social mobility in Northern Ireland and the Irish Republic. The researchers state that they would welcome requests for access to these data. This dataset obtained rankings of lists from 80 occupations by samples of Irish men and women, the mean rankings to be used at a later stage as a basis for an occupational status scale. Employment status, occupation (respondent, father and spouse). General: job description, place of work, employer, number of persons supervised. Farmers: farm size, type, tenure, number of persons employed, rateable value. Self-ascribed occupational title. Background Variables Age, sex, marital status, locality, urban/rural, religion, length of residence.
