Socio-economic research that is application-oriented, always refers to realistic economic and social phenomena. Regional, national and international secondary data on relevant aspects of a project are usually provided by professional institutions, such as Eurostat (statistical department of the EU), Statistik Austria (statistical department of Austria), D-Statis (statistical department of Germany) and the statistical department of the Austrian chamber of trade. Our contract research may also aim, either exclusively or partly, at analysing secondary data systematically and providing it to third parties. Furthermore, we also statistically edit data provided by companies, which is generated for the exclusive internal use of these specific companies.
