Shopping malls became popular in Chile in the early 80?s, and are one of the first signs of the globalizationand liberalization of consumption in Latin America. They are currently one of the main elements of Chilean popular culture, influencing people?s mobility, daily activity, social mixing and segregation processes [1, 2].In this work we analyze the mobility patterns of people going to malls in the Chilean capital city, Santiago,in order to determine which factors influence mall election and what types of social mixing are found in malls. We used Call Detail Records (CDRs) provided by Telefonica R&D. Our study comprises 16 malls and 481 cellphone towers inside those malls. The dataset consists of 1,023,118 unique mobile devices (i.e., containing a Movistar/Telefonica SIM card), of which we identified 942,091 as visitors who went to malls 1,471,637 times in the course of a single month, August 2016.
