[From rings to segregation. Mexico City, 1950-1987].

The author discusses different methods of urban analysis, using the example of Mexico City, Mexico. "In this work two outlines are used: a concentric one that reflects the city's expansion and a segregated one that sees the 'different cities' within. We analyze the commercial occupation of central areas and the growth due to the expansion of the periphery from 1950 to 1986. In both processes, the massive expulsion of the inhabitants appears, firstly as an effect and secondly as a cause. This fact serves as an argument to explore certain proposals in a prospective dimension. In the technical [spatial] analysis we generally avoid the design of the city itself. Here we approach some design ideas without forgetting their social dimension." (SUMMARY IN ENG) excerpt
