Expanding the theoretical foundation of differential urbanization

"Recently, the concept of differential urbanization was introduced. It conceptually links the processes of urbanization, polarization reversal, and counterurbanization across the development spectrum in the First and Third Worlds. Based on supporting evidence in developed and less developed countries, this study expands the theoretical foundation of the concept by first focusing on a graphical analysis of the processes of urbanization, polarization reversal, and counterurbanization. Secondly, it looks into the explanations given for counterurbanization. Thirdly, factors likely to influence post-counterurban migration trends are discussed, and finally, the relevance of certain causes of differential urbanization given in the literature are explored."
