Urban Politics and Sociodemographic Changes in Mexico City's Urban Center ?Gentrification or Resettlement?

In the last decades there have been significant changes in Mexico City's urban core. The hegemonic thought has often interpreted these changes as a process of building upgrading and resettlement. At the same time, some scholars are denouncing a gentrification process and the substitution of the poorer dwellers for more affluent ones. This paper develops a historical review of the urban center devaluation and revaluation and its relation to more recent sociodemographic changes by exploring the Mexican census. As a result, the research highlights a series of sectors in the urban core where strong public or private investment coincides with the social upgrade of its population.
