STUDENT WILL… Be able to discuss Ravenstein’s laws of migration Be able to discuss the gravity model Be able to discuss push & pull factors of migraiton
LANGUAGE CHECK Emigrate: Leaving your country for good for another. Immigrate: Coming to a country. I shall emigrate from Egypt to immigrate to Iceland. (I left Egypt and am going to Iceland).
GRAVITY MODEL Gravity Model: states that spatial interaction is directly related to the populations and inversely related to the distance between them. Works like gravity: Things are going to be drawn to the thing with a larger mass. Distance between the two objects are going to influence their pull Cities are the “thing” and their “mass” is the population People are drawn to larger cities, but distance may erode that pull Will come up again…
RAVENSTEIN’S LAWS OF MIGRATION 1) Every migration flow generates a return or counter- migration. 2) The majority of migrants move a short distance 3) Migrants who move longer distances tend to chose big-city destinations 4) Urban residents are less migratory than inhabitants of rural areas 5) Families are less likely to make international moves than young adults.
PULL FACTORS PUSH FACTORS Push-Pull Model: Everett Lee 1966 The “why” of people voluntarily migrating/Ravenstein is telling you “where” Not always perfect, intervening obstacles Costs Border crossing difficulties Visas Leaving family behind
