Pittsburgh
Pittsburgh became a major American city due to its emergence
as a major industrial center of the world in the 19th century.
Its population is around 1.5 million, including its immediate
suburbs, spread over several counties. The city population is
continuing to decline, even today, since the demise of the steel
industry in the 1960s and 70s. The physical makeup of Pittsburgh
is defined by three rivers and their dramatic topography.
Ankara became a major Turkish city due to its designation as the capitol of the young republic in 1923. Its population has reached 3 million representing an 100 fould growth in 75 years. The surface area of the city and its hinterland is less than half of that of Pittsburgh, signaling the high population density it possesses. The physical makeup of Ankara is that of a dramatic mountanous topography rising above the central anatolian platoe surrounding it.
