The key elements behind the choice of a residential unit by a group or individual, may affect in a positive or negative way the different types of mobility that are carried out over the territories through several spatial practices. When these mobilities present difficulties at the time of moving, either physical (commuting), social, cultural, etc., these practices become complex. The present study hopes to grasp this reality from the choosing of the residendial unit and the quotidian mobility, focusing analysis on low-income Latin American migrant homes, and how they move across the area, modifying territories, primarily on the central area of the city of Iquique. Using fieldnotes and in-depth interviews, this work analyses the impact and costs that the choices of location have in the city, regarding the experiences and daily life of the poor migrant homes.
