Population health monitoring and reporting provides regular and up-to-date information on health outcomes and its determinants. The outputs of population health monitoring aim to inform policymakers and other stakeholders to develop fact-based decisions. Population health monitoring is located at the national, but also federal state and county level. This paper describes the legal basis for population health monitoring in the federal states' public health acts as well as current challenges and possibilities for further development from a federal state and county perspective on population health monitoring.A legal basis for population health monitoring on the federal state and county level exists for almost all federal states in Germany. The level of detail of these laws varies in terms of responsibility, periodicity of population health monitoring and reporting, content, and designated use. Population health monitoring needs to respond to challenges in the areas of population health monitoring resources, data sources, (intersectoral) reporting, and impact. Practical examples illustrate how the challenges can be handled and further development can take place.Based on its solid legal basis, being a routine task, and its close link to the living conditions of the population, population health monitoring on the federal state and county level has the possibility for cocreating public health at the grassroots level and to be a pioneer for health equity.
