The Social Survey Austria (SSÖ) is a programme for monitoring changes in attitudes and value orientations in the Austrian population. The questionnaire consists of annual modules of the International Social Survey Programme (ISSP), collected in around 45 countries, and a national part with questions on current social issues in Austria. The surveys are based on representative samples of the Austrian resident population aged 18 and over. By replicating question complexes in the survey waves and linking the SSÖ and ISSP, it is possible to analyse development processes and social change in Austria over time and in an international comparison. The surveys are supplemented and deepened by accompanying methodological studies.
