Solution:The order of urban growth proposed by Mumford is: Eopolis → Polis → Metropolis → Megapolis → Tyrnopolis → Necropolis. Just as a human being passes through the stages of infancy, youth, adulthood, and old age from birth, a city also passes through various stages of development from its inception to its development, during which a small town transforms into a metropolis or megacity.
The contributions of Patrick Geddes, Lewis Mumford, and Griffith Taylor are noteworthy in studying these stages of urban development. Patrick Geddes identified three stages of urban economic development based on the location, functions, economic, and historical relationships of cities:
(1) Primitive Economy (Primitive Economy), (2) Archaic Economy (Paleolithic Economy), and (3) New Technology (New Technology). Lewis Mumford (1938), after a detailed study of the functions and historical facts of cities, described six stages of their development. Griffith Taylor (1953) described seven stages of urban development.
