Research guide

Research landscape

Germany has a large and mature research industry. Agencies are spread across several hubs rather than one capital, with major centres such as Frankfurt, Hamburg, Munich, Berlin and Nuremberg. Full-service agencies work alongside specialist qualitative, B2B and healthcare firms, field and telephone studios, and online panel providers.

The industry is organised by four associations: ADM (agencies), ASI (social research institutes), BVM (professional association of researchers) and DGOF (online research). In a joint declaration of 23 February 2026 they adopted the ICC/ESOMAR International Code (2025 edition) as part of the German rules of professional conduct, completed by joint guidelines (Richtlinien) on telephone and online surveys, interviews with minors, recordings and observation, mystery research and healthcare studies.

Languages and fieldwork

German is the fieldwork language for almost all studies: questionnaires should be translated by native speakers and tested before fieldwork. 26.3% of the population has an immigrant history, and the largest foreign nationalities are Turkish (1.39 million), Ukrainian (1.17 million) and Syrian (0.86 million): studies of migrant audiences may need translated questionnaires or bilingual interviewers.

A national sample covers 16 Länder (federal states), led by North Rhine-Westphalia (18.0 million people), Bavaria (13.2 million) and Baden-Württemberg (11.2 million). Quotas or weighting by Land and by East/West are common, because regions differ: in 2025 the population fell by 0.5% in the East and 0.1% in the West, and the average age ranges from 42.2 years in Hamburg to 48.3 in Saxony-Anhalt. With 23.7% of people aged 65 and over, older age groups need careful coverage.

Which methods work

Connectivity is high: 93.5% of individuals use the internet and there are 129 mobile subscriptions per 100 people. Online surveys using access panels are widely used for consumer and B2B research. The German online survey guideline warns, however, that self-recruited respondents are generally not suitable for results that can be generalised to the population.

Older people are less well covered online: in 2025, about one in ten people aged 65 to 74 had never used the internet. Telephone interviews (CATI) and face-to-face interviews remain used for older and offline audiences. The telephone guideline sets call times for private households: Monday to Friday 9:00 to 21:00, Saturday 10:00 to 20:00, Sundays and public holidays 10:00 to 18:00, with at most 10 attempts per number. Focus groups are usually held in dedicated studios in the major cities.

Timing

Summer school holidays are staggered by Land: in 2027 they start on 28 June in Hesse, Rhineland-Palatinate and Saarland and end on 13 September in Bavaria. Families and business respondents are harder to reach during this period, so check the dates of the Länder in your sample and allow more fieldwork time.

Christmas holidays run from 21 December 2026 to as late as 12 January 2027 depending on the Land: avoid starting fieldwork in late December. Some public holidays also differ between Länder.

Data protection

Personal data is governed by the GDPR and the Federal Data Protection Act (BDSG). For private companies, including research agencies, supervision is carried out by the data protection authority of each Land, not by a single national regulator.

German research rules add strict requirements: data may be passed to clients only in anonymised or pseudonymised form, and a respondent’s consent cannot lift this requirement. Research must be separated organisationally and technically from non-research activities, especially direct marketing and sales promotion. Ask your agency how respondents are informed, where the data is hosted and how recordings or video from qualitative work will be shared.

Working with a local agency

• Share a clear brief: objectives, target, sample size, Länder and regions, method, languages and deadline.
• Ask whether the agency is a member of ADM or BVM and follows the German research guidelines.
• Ask which panels or telephone studios will be used, and how quotas by Land, East/West, age and gender are set and weighted.
• Expect anonymised results: identifiable respondent data, CRM matching or follow-up sales contacts are not part of a research project.
• Agree in writing who is controller and who is processor of the personal data, and the retention period.
• Compare several proposals: you can send one request to up to 5 companies from this page.
