The Rhine-Ruhr Area in Germany, ranks among the large metropolitan areas in the world, estimated at about 12 to 14 million people - 1,699/km². It spreads from the Ruhr area megalopolis in the north to the urban areas of the cities of Düsseldorf, Wuppertal, and Cologne in the south.
There are many different definitions of what belongs to the Rhine-Ruhr area: As a result of suburban sprawl, today some people include 130 towns and cities and say the most northern town of Rhine-Ruhr would be Dülmen, the most eastern Soest, the most southern Bad Honnef, and the most western Venlo in the Netherlands. The "Rhine-Ruhr metropolitan area" in such a definition is the base for over 300,000 companies and 45 universities.
