There is abundantWalking evidence demonstratingDeprived neighborhoods that the built environmentBuilt environment influences human behavior, people's travel patterns, and in particular, their willingness to make walkingWalking trips. However, there is little clarity about the impacts that the built environmentBuilt environment has on walks that occur in deprived neighborhoodsDeprived neighborhoods. The few studies that have addressed the matter indicate that the built environmentBuilt environment is of little relevance in contexts of social deprivation since other phenomena (such as insecurity) and the lack of resources are more important, making walkingWalking an activity that must be carried out regardless of external conditions. This chapter seeks to delve into that discussion and explore the ways in which the built environmentBuilt environment affects the walks that occur in deprived neighborhoodsDeprived neighborhoods. Thus, the results of 42 semi-structured interviews are reported in which residents of 3 deprived neighborhoodsDeprived neighborhoods in Santiago de ChileSantiago de Chile were invited to talk about the built environmentBuilt environment and the difficulties they face when walkingWalking. The results indicate that the built environmentBuilt environment influences the walk of the deprived neighborhoodsDeprived neighborhoods of SantiagoSantiago in at least three ways. The urban structure reinforces boundaries and dichotomies, restricting the area that is considered safe and, therefore, walkable. The deterioration of the built environmentBuilt environment can turn walkingWalking into an unpleasant practice; while poor pedestrian infrastructure prevents the realization of recreational activities and transforms walkingWalking into a permanent reminder of the profound inequalitiesInequality of society and the few opportunities they have to integrate into it.
