摘要:The rather swift urbanization of Mexico during the Twentieth Century has resulted from the rapid industrialization that took place until 1982, which transformed the nation. It is considered, therefore, that in order to understand the accelerated growth and multiplication ofMexican cities it is necessary to start from their linkage to processes ofoverall changes brought about by industriali zation and economic development. The first objective ofthis paper is to analyze the main characteristics ofthe overall process ofurbanization in Mexico in the context of its economic development and, secondly, the phenomenon of the emerging megalopolis in Mexico City and the metropolitan consolidation of Monterrey.
