This text describes and analyzes locational patterns of various economic and urban activities: where those activities locate and why, striking a balance between theoretical and empirical approaches. Whilst combining location/spatial interaction approach with description (empirical approach) of economic patterns, thus providing a balance between the dominant approaches of the last three decades the book contains unmatched coverage of North America, particularly the US and relates 1980's urbanization to economic geography concepts. In this new edition, the entire energy presentation has been reworked to highlight the changes in US energy production, consumption and alternative sources since the 70s. Also, coverage of urbanization and agriculture has been substantially revised and updated to reflect recent trends. Finally, all empirical data has been updated through the mid-80s.
