The term city can be used to mean either an area of contiguous urbanization or a particular municipality (an area within the political borders of an incorporated municipality). There is a substantial variation in municipalities around the world. The largest municipality, Chongqing, is approximately the same size as the state of Indiana and contains much more rural territory than continuous urbanization. In most cases, however, the continuous urbanization popularly thought of as the city extends well beyond the boundaries of the core incorporated city.
