UNIT 2 LESSON 09

STUDENT WILL…

Be able to discuss Ravenstein’s laws of migration

Be able to discuss the gravity modelBe 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 distance3) 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 1966The “why” of people voluntarily migrating/Ravenstein is telling you “where”
