Infratest dimap

Experts in electoral and political research


Infratest dimap’s beginnings go back to the year 1990. In that year – only a few months after the fall of the Berlin Wall – Infratest founded the “Infratest Burke Berlin” institute in Berlin for the purpose of scientifically observing the convergence process between the Western states of the old Federal Republic of Germany and the Eastern states of former East Germany. The decision by the federal Parliament in 1991 to relocate the seat of government from Bonn to Berlin triggered the launch of a high-capacity and highly innovative team specialising in electoral and political research and based in the new capital.



In 1996, the Berlin Infratest institute and the dimap institute in Bonn were jointly awarded the contract to conduct the electoral research for the election coverage of ARD (the leading national public TV channel). This was the starting point which led to the founding of the joint enterprise Infratest dimap. Since then, our institute has provided research data for the ARD on local, state and federal elections in Germany as well as elections to the European Parliament.



Today, Infratest dimap is one of the most powerful providers of electoral and political research in Germany. In addition to ARD and its affiliated stations, our clients include a host of daily and weekly newspapers, journals and magazines as well as government agencies, trade associations, universities, embassies, international organisations and commercial enterprises.



A staff of 20 permanent employees works for Infratest dimap at the Berlin office located in the district of Treptow. The majority of these employees are professionally qualified and designated experts in empirical social research. They are responsible for the conceptualisation and execution of surveys, the analysis and interpretation of results and the provision of consulting services to our clients. A large team of trained and experienced freelance interviewers is at our disposal to conduct telephone surveys or other interviews on location (e.g. exit poll in electoral precincts). On election days, as many as 1.200 individuals are on duty throughout Germany to carry out interviews for Infratest dimap.


Technical Infrastructure

Data collection for quantitative surveys is conducted via the TNS Infratest technical infrastructure. For telephone interviews, Infratest dimap uses a cutting-edge studio in Berlin which provides 64 computer-assisted telephone stations. Seven more studios are available across the country as needed. They provide a total of 656 additional CATI stations.


Research Network

As a member of TNS, with representations in over 70 countries around the world, Infratest dimap is part of a vast global network of research institutes. In the sector “polling & social”, numerous experienced institutes dedicated to electoral and political research within the TNS Group in Europe and on other continents permanently interact and exchange ideas.
When conducting international surveys Infratest dimap utilises resources available from partner institutes in all European countries, the US and other parts of the world.
