  1. Chapter 3 “Migration”

  2. Migration: … Immigration: … Emigration: … Net Migration=Immigration-Emigration Relocation Diffusion: …

  3. Define the following: Human Mobility - Circulation, Migration Place Perception - Distance Decay - Space Time Compression – we have seen this before Gravity Model - Ravenstein’s Laws of Migration -

  4. Distance Decay Discuss the above graph!

  5. One important aspect of the movement of people is Spatial Interaction. • Spatial Interaction decreases with distance - distance decay • With improved communication and transportation this is now changing - space time compression • … - migration stream. People tell people - migration chain.

  6. Gravity Model – … • … • …

  7. Gravity Model: Distance and Size of places are taken into account.

  8. Iij= predicted interaction between origin iand destination j. k = factor scales the “relative” levels of interaction. Phone calls → high value, Air travel → med. value and Migrants → low value Sometimes used as a scaling constant to adjust certain characteristics like: time (one week/one year), climate, landforms, borders etc. b below can also be used to adjust.

  9. Pi = a measure of size, usually population, for origin I Pj = a measure of size, usually population, for destination j dij = distance between origin i and destination j β = an exponent that adjusts the rate of decay unique to the type of interaction – sometimes called a “transport constant “– the efficiency of the transport system between the two the two locations. A highway will have a weak value whereas a road will have a high value or are you measuring the movement of goods or the movement of information

  10. Lee’s Model of Migration: Draw this into your notes and we will fill it in together!

  11. Ravenstein’s Laws of Migration • Ernst Ravenstein – 1885 (British) • … • … • … • … • …

  12. … • … • … • … • …

  13. The next few slides illustrate Canadian Migration over time. Let’s analyze these stats and try to determine the titles for some.

  14. Vancouver by Source Area What do you think Toronto’s would look like?

  15. Source: The Immigration Program. Ottawa: Manpower and Immigration, 1974. Note the changes through time!

  16. Immigration by Top Ten Source Countries More Change!

  17. A question! • Canada’s immigration policy (multiculturalism and the point system) will benefit Canada in the future on 3 very important counts: • Quebec/Canada relationships • Domestic Employment • The Global Economy • Comment on the above statement/hypothesis • What does the above mean? • Do you agree or disagree

  18. Inter-regional migration in Canada

  19. Major inter-provincial migration flows 1996-2001 Observations? “Human Geography: by Paul Knox

  20. Intra-regional Migration in the U.S. What is Counter- Urbanization? Average annual migration among urban, suburban, and rural areas in the U.S. during the 1990s. The largest flow was from central cities to suburbs.

  21. Can you explain this Net Migration Map of the US?

  22. Center of Population in the U.S. The center of U.S. population has consistently moved westward, with the population migration west. It has also begun to move southward with migration to the southern sunbelt. I could not find Canada’s center of Population – Where do you think it is?

  23. Migration from Latin America to the U.S. Mexico has been the largest source of migrants to the U.S., but migrants have also come from numerous other Latin American nations.

  24. Concrete wall built to separate San Diego from Tijuana, Mexico (2000)

  25. To try and slow down the massive Mexican migration into the US. Maquiladoras were set up in Mexico near the US border. • Positive Migration: • Quintana Roo • Baja – Nord • Baja – Sur • Chihuahua • Mexico • Negative Migration: • Distrito Federal • Guerrero • Zacatecas • Oaxaca • Veracruz Hallow Core Explain! Mexico City

  26. Maquiladora comes from the Spanish word maquilar meaning "to perform a task for another." Today, maquiladora …

  27. Global Migration Patterns The major flows of migration are from less developed to more developed countries.

  28. Net Migration (per population) Net migration per 1,000 population. The U.S. and Canada has the largest number of immigrants, but other developed countries also have relatively large numbers.

  29. Location of Refugees - 2000 Observations?

  30. Flow of Refugees – Can you name the Hotspots?

  31. Some final key terms: • Brain Drain • Time Contract Worker • Guest Worker • Transhumance • Inter-region • Intra-region • Intervening Obstacles • Push/Pull Factors

  32. Vocabulary List

  33. Activity space Chain migration Cyclic movement Distance decay Forced Gravity model Internal migration Intervening opportunity Migration patterns • Intercontinental • Interregional • Rural-urban  Migratory movement Periodic movement Personal space Place utility Push-pull factors Refugee Space-time prism Step migration Transhumance Transmigration Voluntary

  34. The End!
