A very large urban settlement usually with accompanying suburbs. No precise parameters of size or population density have been established. The structural, functional, and hierarchical evolution of global metropolises is rooted as much in the past as in the present: modern information and communications technology may be more advanced than the 19th-century telegraph, but the processes and outcomes are much the same (Daniels (2002) PHG26). ‘[Berlin's] wealth of facilities, as well as their scatter across the metropolis, can be understood only in the light of the city's history and, paradoxically, its troubles’ (Grésillon (1999) Cult. Geog. 6).
