Since then, Dudweiler has also been the name of one of the four city districts (Stadtbezirke) of Saarbrücken. The district of Dudweiler comprises four city boroughs (Stadtteile): Dudweiler, Herrensohr, Jägersfreude (both were boroughs of Dudweiler before 1974), and Scheidt (a municipality in the amt of Brebach before 1974).
The coal mining industry played an important role for the growth of Dudweiler until 1968 when the last mine was closed. Today Dudweiler is characterised by its proximity to the Saarland University campus.
