Urban life has been profoundly altered by new technologies that offer multiple alternatives for communicating, working, consuming, creating, and expressing oneself. In major Latin American cities in which old and new problems intermingle, young people and adolescents are heavy users of these technologies. This article details these new uses of information and communication technologies in these cities and expands upon their potential. Changes in the urban economy are identified and spearheaded by highly qualified young people, who work independently and/or interact flexibly by way of various networks. These young people derive their added value primarily from creativity, knowledge, and cultural innovation, becoming involved in alternative circuits such as those of design or of organic and artistic products. However, urban poverty, spatial injustices, violence, and insecurity continue to weaken these spaces of social coexistence as well as emptying public spaces that are key to the success of this new urban economy. This article sheds light on the new urban, working, and artistic experiences of young people in Latin American cities and the similarities and differences they have with their peers elsewhere in the world.
