Causes of Migration AP Human Geography

Objective By the end of this lesson, students will be able to analyze and understand the causes of migration, both voluntary and forced.

Why move?? People move for a number of reasons Better homes, jobs, climate, etc. Migration involves a decision, but it can sometimes be a “forced” decision rather than a voluntary one.

Types of Migration Forced Voluntary Rural to Urban Urban to Rural In Search of Work Better Climate War Persecution Disasters Hazard-ous events Survival Desires

Voluntary Migration Rural To Urban: People are attracted to “glamorous” employment opportunities in cities Urban to Rural: Weary of city life and the high cost of living, people seek refuge in the tranquility of the countryside International Migration: people are motivated for many reasons to travel overseas and begin new lives.

Forced Migration Natural disasters like hurricanes, floods, earthquakes and the spread of disease have all encouraged people to move War and persecution are extreme examples of forced migration Civil War has led people to move to nearby countries

Lees Model of Migration 1966 (Model to explain forces in migration) It introduced the idea of intervening obstacles that need to be overcome before migration can take place Source and destination are seen as possessing a range of attributes: each “would-be migrant” perceives these attributes differently depending on age, race, gender, marital status, etc.

Lee’s Model

Intervening Obstacles Factors, real or perceived, that might prevent migration. Passport documents Learning to drive Learning a new language Schools for children

Intervening Opportunity The presence of a nearer opportunity that greatly diminishes the attractiveness of sites farther away.

Common Examples of Push and Pull Disagreeable Climate Lack of Employment Opportunity High Cost of Living Pollution Overcrowding Pull Agreeable Climate Employment Opportunities Clean Air Family Connections and Friends Push and Pull is COMPLEX because people all have different perceptions of places. What attracts some people to a place also serves to repel others.

Test Your Knowledge!

In the next few slides, there will be a migration story. Figure out if the example is demonstrating a: push factor, pull factor, intervening obstacle or intervening opportunity. Write your answers down in your notebook, and we will review at the end.

Intervening Obstacle Intervening Opportunity Pull Factor Push Factor A new mayor is elected in Chicago. His new city plans include shutting down many schools and cutting school budgets. Now, Mr. Wilson, a resident of Chicago, has a son who is now in an overcrowded classroom of 40 students and there’s less of a budget to improve the school and hire high quality teachers. Him and his wife decide out to the suburbs.

Intervening Obstacle Intervening Opportunity Pull Factor Push Factor Liliana decided she wanted to study abroad in Australia. When she filled out her paperwork to get her passport documents, she realized that she may not get them in time to leave. She paid extra to have them shipped faster, but they still didn’t get there in time. She ended up having to put off studying abroad until next semester.

He has made such a name for himself, that the Google office out of Los Angeles offers him a job with twice the pay and more vacation time. Also, you can’t complain about the weather in LA.

Ravenstein’s Laws of Migration 1. The majority of migrants move short distances. They may move in steps, but they move short distances.

Ravenstein’s Laws of Migration 2. Those who move far away, move to cities

Ravenstein’s Laws of Migration 3. Urban residents are less migratory 4. Most migration is rural to urban.

Ravenstein’s Laws of Migration 5. Families are less migratory than young adults

Ravenstein’s Laws of Migration 6. Most international migrants are young males, while most internal migration are female.

Formal Sector Jobs Most fortunate migrants will find jobs here. A regular wage that gives some access to the other advantages of urban life. Let’s think of some examples

Informal Sector Jobs Because the demand for jobs generally is greater than supply, many migrants can do no better than this. These jobs generally require very little skill or education There is no set wage Let’s think of examples
