Total numbers of laboratory animals in Germany and at the Bernhard Nocht Institute

Current figures on laboratory animals for the Federal Republic of Germany and the federal states in 2022 and 2024 can be found in the fact sheet published by the ‘Understanding Animal Testing’ information initiative and are also available on the website of the Federal Institute for Risk Assessment.

Facts and figures for Germany

In the Federal Republic of Germany, the number of laboratory animals has remained stable in recent years, despite a steady increase in research activity. Mice are the most commonly used animals in laboratory experiments. The slight decline in the number of laboratory animals in 2022 is attributable to exceptional circumstances resulting from the coronavirus pandemic worldwide.

A bar chart showing the number of laboratory animals from 2002 to 2024. The number of laboratory animals fluctuates between 2.1 million (in 2003, with 1.2 million mice) and 3.1 million (in 2012, with 2.2 million).

BNITM Facts and Figures

In our animal-based research, we use only rodents, of which mice are the most common. The ‘other rodents’ refer to the African rodent Mastomys natalensis (Natal multimammate mouse), which is the natural reservoir host of the Lassa virus.
