The ISSP is a continuing annual programme of cross-national collaboration on surveys covering topics important for social science research. It brings together pre-existing social science projects and coordinates research goals, thereby adding a cross-national, cross-cultural perspective to the individual national studies. The ISSP module was fielded as a core part of the survey on Social Inequality and Justice and it covered general evaluation of inequalities, the role of government in relation to inequalities and social problems, factors of wage differences, support for further growth of inequalities, estimates of actual and just wages in selected professions, causes of the wealth ant the poverty, evaluation of social tension between selected social groups, general typology of differentiation in society. In addition to the ISSP module the questionnaire included also questions from the Social Justice surveys (lnternational Social Survey).
