megalopolis (mĕgəlŏpˈlĭs) [key] [Gr., = great city], a group of densely populated metropolitan areas that combine to form an urban complex. It was first used in its modern sense by Jean Gottman (1957) to describe the huge urban area along the eastern seaboard of the United States from Boston to Washington, D.C. According to Gottman, it resulted from changes in work and social habits.
