A "Landkreis" is a district in Germany that serves as an administrative region. It is responsible for local governance and public services, such as education, transportation, and healthcare. Each Landkreis is made up of several municipalities, which are smaller towns or cities. Landkreise play a crucial role in the federal structure of Germany, as they help implement national policies at the local level. They are governed by elected officials and have their own budgets to manage local affairs. The system of Landkreise ensures that residents receive essential services tailored to their specific needs.
