Ravenstein’s -Laws of Migration-
• Most migrants travel short distances…… Why?• They generally move towards great commercial centers….. Why?• Each movement has a counter-movement in the opposite direction.• Long distance movements are directed towards big cities.• People in urban (city) areas migrate less than rural (farm) areas….. Why?• Males migrate the farthest but females migrate the most….. Why?• People mainly move for economic ($$) reasons.• City housing is inadequate and ghettos or shanties are formed.
