Many research questions require (statistical) knowledge of manufacturing. The available data are often not collected at the level of German states, or many sub-sectors are grouped in such a way that the questions cannot be answered directly. For these reasons, project work often requires supplementing statistical data sources by other data sources, e.g. interviews or ad-hoc surveys. In general, the latter are costly and/or do not provide an overall picture of the analyzed aspects of the industry. This subproject aims to explore data-driven methods to enrich statistical data on manufacturing using the German non-ferrous metalworking sector as a test case.
