| While Dortmund in recent years has overtaken Essen as the largest city of the Ruhr (or rather: Essen depopulated faster than Dortmund), it is still known to many as "Essen region". So that could be one alternate more for Dortmund (next to Ruhr/Ruhrgebiet/Ruhr area). Also, "incl. Bochum" does not make much sense (not your fault but the sources), since there are larger cities in the area which could have been mentioned instead (Duisburg, depending on the precise borders Düsseldorf). |
