The Institut für Demoskopie Allensbach (IfD Allensbach), often referred as the "Allensbach Institute," is a private conservative opinion-polling institute, founded by Professor Dr. Elisabeth Noelle-Neumann (1916-2010) in 1947. It is one of the most well-known and respected opinion and market research institutes in Germany. Research by the Allensbach Institute covers the entire spectrum of survey research-in terms of both the topics investigated and methods used-ranging from social research to current political opinion research, from market research and media analyses to surveys for legal evidence. In addition to representative surveys of the total population, the Institute also conducts surveys among specific target groups, for example, certain segments of the population or professional groups, persons in key positions in different business sectors, company customers/employees and the readers of various newspapers and magazines. The extensive and carefully maintained Allensbach Archives are one of the Institutes special features. Here, all surveys, reports and studies by the Institute are stored, thus enabling us to quickly obtain an overview of current research findings and to connect these with the findings of long-term trend investigations, some of which have been conducted for decades. The most important findings are documented regularly in the Allensbach yearbooks; The Allensbach Institute is the only German survey research institute that has a cooperation agreement with the German Federal Archives in Koblenz, where a complete copy of all documents from the Allensbach Archives is stored. The institute employs one hundred full-time employees, including 25 scientists, and two thousand avocational interviewers, and conducts one hundred surveys approximately and 80,000 interviews yearly. Although the institute conducts surveys primarily of German public opinion, it has participated in or carried out multiple "International Opinion Research Projects".
