The social and spatial processes which takes place in informal urbanization (i.e. physical consolidation, immigration and emigration) normally take years, if not decades, before it becomes evident or is observable. Not only time, but further characteristics of the settlement makes the processes increasingly visible and clear. In young and relative small settlements, i.e., the long term effects on the inhabitants and the buildings would occur just as isolated cases and not as collective and spatially aggregate decisions, as it is hypothetically expected. This is the reason why Ciudad Nezahualcóyotl was chosen, as it serves as an ideal case study.
