Since the reunification of the Federal Republic of Germany with the German Democratic Republic in 1990, Germany, situated in middle Europe, has become the most populous country in Europe with 83.5 million inhabitants. With a gross domestic product of 3.8 trillion U.S. dollars (2020), it is the largest national economy in the European Union and the fourth worldwide. As a result of the political reorganization after World War II, a federal organization has been adopted, delegating a large number of tasks to each of the 16 federal states, thereby, enabling a more regionalized approach (e.g., education or the health system).
