Urban anthropology consolidated in the 1970s-80s and became an important section of anthropology and urban studies. It embraces four main fields: (a) urban ethnography to highlight urban conditions and lifestyles, (b) the comparative study of cities as wholes, (c) anthropological studies of urbanization as a process of regional, national, and global social change related to all sorts of problems, especially poverty and slums, urban inequality and ethnicity, and urban environmental and conservation issues, and (d) fieldwork under specific urban conditions.
