Based on research exploring cultural processes in Mexico City, this article compares styles of study in sociology, anthropology, and communications studies. How can these three perspectives be combined to explain the complexity of a megacity as well as the multiplicity of groups and sectors into which it is fragmented? This article also analyzes the role of local traditions in the globalization of urban life, and the reformulation of the anthropological discourse that is necessary in order to speak of the Other in cities torn by multiculturalism. Relating to this point, some differences between postmodern urban thought in the U.S.‐European metropolis and in Latin America are suggested.
