Cities

A city is an urban area, differentiated from a town, village, or hamlet by size, population density, importance, or legal status. In most parts of the world cities are generally substantial and nearly always have an urban core, but in the United States many incorporated areas which have a very modest population, or a suburban or even mostly rural character, are designated as cities. City can also be a synonym for "downtown" or a "city centre".
