context_page_description: The Rhine-Ruhr metropolitan region is the largest metropolitan region in Germany with over 10 million inhabitants. A polycentric conurbation with multiple major urban concentrations, the region covers an area of 7,268 square kilometres, entirely within the federal state of North Rhine-Westphalia. The Rhine-Ruhr metropolitan region spreads from Dortmund-Bochum-Essen-Duisburg in the north, to the urban areas of the cities of Mönchengladbach, Düsseldorf, Wuppertal, Leverkusen, Cologne, and Bonn in the south. The location of the Rhine-Ruhr at the heart of the European Blue Banana makes it well connected to other major European cities and metropolitan areas like the Randstad, the Flemish Diamond and the Frankfurt Rhine Main Region.
  The metropolitan area is named after the Rhine and Ruhr rivers, which are the region's defining geographical features and historically its economic backbone.
