[A new migratory horizon in Central Mexico: 1970-1990]

"During the last few decades migration in Central Mexico has undergone important changes. Not only have populations been moving increasingly towards the periphery and decreasingly towards the center, but those originally living in the center are also moving to the immediate periphery. This behavior allows us to claim that Central Mexico is undergoing a process of deconcentration or suburbanization. This study describes the way in which such a process has developed and the situation of geographical entities within that process. Analysis of the new regional configuration takes into account demographic growth and the direction and characteristics of migration in the Mexico City Metropolitan Area and its surrounding states during the last twenty years."
