Chapter 3
“Migration”
Migration: Permanent move to a new location.
Immigration: to a location
Emigration: from a location
Net Migration=Immigration-Emigration
Relocation Diffusion: Spread of characteristics
through the bodily movement of people from
place to place.
Immigration by Country
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
Migrants move in well defined channels from origin
to destination - migration stream. People tell people
- migration chain.
Gravity Model – mathematical prediction of the
‘strength’ of spatial interaction between places
– Spatial interaction (such as migration, trade,
communication, commuting, shopping etc.)
is directly related to the populations and
inversely related to the distance between
them in other words spatial interaction
decreases with distance
– In mathematical terms: Interaction is
proportional to the multiplication of the two
populations divided by the distance between
them
Gravity Model:
Iij  k
Pi Pj

dij
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 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.
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!
Ravenstein’s Laws of Migration
Ernst Ravenstein – 1885 (British)
1. The majority of migrants move a short
distance.
2. Migrants who move longer distances tend to
choose big-cities.
3. Urban residents are less migratory than
inhabitants of rural areas.
4. Each movement produces a compensating
counter movement in the opposite direction.
5. Males migrate more over long distances and
females migrate more over short distances.
6. Families are less likely to make
international moves than young adults.
7. People mainly move for economic reasons
8. Urban housing development is inadequate
for the influx of migrants in LDC’s thus
ghettoes/shanties are formed.
9. Most migrants are between the ages of
20-34
10. Migrants move in well defined channels
from origin to destination – called a
migration stream. Migrates will tell other
people creating a migration chain and
sometimes migrates change their minds
and go back – migration counter stream.
The next few slides illustrate Canadian
Migration over time. Let’s analyze these
stats and try to determine the titles for
some.

More Change!
A question!
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
Comment on the above statement/hypothesis

Inter-regional migration in Canada
Major inter-provincial migration flows 1996-2001
“Human Geography: by Paul Knox
Observations?
Can you explain this Net Migration Map of the US?
Intra-regional Migration in the U.S.
What is CounterUrbanization?
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.
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
Explain!
Hallow
Core
Mexico City
Maquiladora comes from the Spanish word
maquilar meaning "to perform a task for another."
Today, maquiladora refers to a Mexican
corporation, wholly or predominantly owned by
foreigners, which assembles products for export
to the U.S. or other foreign country or Mexico
Market. Foreign corporations wishing to reduce
their manufacturing costs in order to become
more competitive in a global economy, may
achieve this goal by setting up a Maquiladora or
Shelter operations in Mexico. This means taking
advantage of a special customs treatment, less
expensive labor costs and lower operating
expenses available in Mexico.
What is a Guest Worker?
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.
