Net Migration=Immigration-Emigration
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 -
Distance Decay
Discuss the above graph!
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.
Gravity Model – …

Gravity Model:
I kP P
dij
i j
ij
Distance and Size of places are taken into account.
Iij = predicted interaction between origin i and destination j.
k = factor scales the “relative” levels of interaction. Phone calls → high value, Air travel → med. value and
Migrants → low valueSometimes 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.
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
Lee’s Model of Migration:
Draw this into your notes and we will fill it in together!

Immigration by Top Ten Source Countries
More Change!
Canada’s immigration policy (multiculturalism and the point system) will benefit Canada in the future on 3 very important counts:
1.Quebec/Canada relationships
2.Domestic Employment
3.The Global Economy

A question!
Inter-regional migration in Canada
Major inter-provincial migration flows 1996-2001
“Human Geography: by Paul Knox Observations?
Intra-regional Migration in the U.S.
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.
What is Counter- Urbanization?
Can you explain this Net Migration Map of the US?
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?
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.
Concrete wall built to separate San Diego from Tijuana, Mexico (2000)
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

Mexico CityExplain!
Maquiladora comes from the Spanish word maquilar meaning "to perform a task for another." Today, maquiladora …
Global Migration Patterns
The major flows of migration are from less developed to more developed countries.
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.
