Daily urban mobility is one of the most complex and relevant phenomena of contemporary spatial configurations and organizations. However, ignoring contributions from theories of urbanism, its spatiality has been disarticulated by planners who are unawate of the anthropological dimensions of spaces of human beings. The following article tries to develop and problematise urban social exclusion from an urban daily mobility point of view. This approach is important as it sets out the theoretical-conceptual contributions developed recently on both concepts; it analyses the links and relationships between both concepts and their importance to the understanding of urban space; and it sets urban subjects as key figures in the concepts in discussion.
