Define chain migration?
After one or a small number of pioneering migrants have led the way, others from the same rural community follow
Results from strong established rural urban links
Define relay migration?
At different stages on a family’s life cycle different people take responsibility for migration in order to improve the financial position of the family
Define stepped migration?
Rural migrant initially heads for a familiar small town and then after a period of time moves to a larger urban settlement
Define urban hierarchy?
Urban structure - size of city decreases number of people decreases
Very few big cities
Large number of smaller cities
Large towns
Small commuter towns
Define voluntary migration?
The individual or household has a free choice about whether or not to move
Define forced migration?

Lee’s migration model: list of intervening obstacles
Distance Lack of capital Illiteracy Political differences Religion Language Military services Travel costs Mia information Family pressure National policy Bureaucracy
Define lees migration model?
A model which divides factors causing migration into push and pull
These factors are economic cultural or environmental
- unfavourable = push
- attractive = pull
What are intervening obstacles to migration?
Factors that prevent migration from taking place or reduce numbers moving
What is the gravity model based on?
Newtons las of universal gravitation
Sum up the gravity model?
The potential number of migrations will be bigger where the population of the departing and arriving are large
Formula for gravity model?
Number of people moving =
Pop of A * Pop of B
/
distance between them squared
What does the todaro model say is the most influential of push pull factors?
Economic
How does the todaro model say that rural urban migration can be slowed?
By creating investment and new employment opportunities in rural areas
Why does migration occur according to the todaro model?
Individual migrants weigh up the economic costs and benefits
Descrive circular migration?
Migrants do not settle permanently in their new homes
Leave rural home at the time of unemployment returns periodically with. Obey
Describe step migration?
Represents the progressive movement from rural areas (isolated farms and agricultural villages)
to small towns / urbanised commuter cities
to regional centres / large individual cities
to national metropolis
Describe step migration variations?
Direct movement from rural areas to national metropolis
Moving from rural areas to national metropolis but moving back to regional centre
Intention to move from rural area to national metropolis but moving back to small town
Intention to move from rural area to national metropolis but eventually returning to rural area not reisiding elsewhere
What are the three steps of step migration?
Farms and rural areas
Regional centres
National metropolis
What is ravensteins law based on?
Studied migration in the U.K. 1880s
Push factors of rural urban migration?
Lack of economic opportunity
(Poor subsistence farming + lack of incomes for young people)
Population greTer than resources (food shortages)
Housing shortage
Natural disaster
Adverse climates
Pull factors of rural urban migration?
Job prospects
High wages
Attractive environment
Amenities
Consequences of rural urban migration?
Urban issues (overcrowding, lack of sanitation, disease (cholera diahorrea) lack of construction regulation, marsh bog poor land quality) Rural reliance on remittances (further decline as old rely on young) Rural depopulation (less agriculture so less food supply, reliance on imported food) Brain drain (selective migration as young entrepreneurial people leave)
Fiji case study information about core vs periphery migration?
Incomes in rural areas 25% of those in Sura
Incomes in urban areas grew 6x faster than in rural areas
What are the two forms of urban urban migration?
Step migration
Movement within the same urban area (HIC)
Why does movement within the same urban areas occur?
Migrants stay with friends or relatives when they first arrive in city
They become more established they are able to move from squatter camps to migrants areas
Describe urban urban migration that happens generally in the U.K.?
Refugee or asylum seeker accommodation
Undesirable areas e.g. Margate
Where there is an accommodation surplus
Describe intra urban migration?
Within one urban area e.g. Moving house due to
Improved income levels mean that property can be acquired in better areas and housing improvements can take place
Changes in family status often mean a move to a larger property or the building of additional rooms
Describe intra urban migration reasons?
Urban regeneration - gentrification (gentrification: kid Brooke village, shoreditch effect) which affects less affluent social groups
Movement for school catchment areas
Improved income (improve lifestyle or get into school catchment areas)
Where does counterurbanisation occur?
Developed world
Eg chile Argentina and Brazil
Describe counter urbanisation?
Involves the shift of populations from older industrial core areas to peripheral areas as well as a move from larger centres to smaller towns
Examples of why counterurbanisation occurs?
New towns eg Crawley due to world war 2 bombing
Slim clearance (eg New addington)
White flights in the 1960/70
Where growth in car ownership and expansion of commuter routers results in a change in work habits
How many people have left rural areas to seek work? (China case study)
160 million people
12% of the population of china
Outline the reasons why people left rural china?
Seek work in cities (1978 rural income is 40% urban income)
Better standards of living (they can make more in a month working in a factory than in a year in the countryside)
In 1978 how much did farmers earn?
Less than $2 a day in 1980
In Giozhou
Urban sprawl in china?
Shenzhen since 1978 has sprawled from small town to city of 12 million, predicted to be 15 million by 2020
Describe the social problems of rural urban migration in china?
61 million children left behind
20 million have mental health problems (depression anexity)
20 million involved in criminal activity
Further health problems of anaemia and screwed growth
Explain what stepped migration is?
When a rural migrant first heads for a familiar small town which is relatively close by
And makes one or more moves up the settlement hierarchy e.g. To a regional centre then to a capital city
Why does stepped migration happen?
Reduced the risk involved and to help the migrant on their way
By offering smaller steps which may be easier to achieve
Allows money to be saved up and information to be gathered for the next step
Explain how pull factors cause economic migration?
Pull factors in the decision to move and choice of destination (factual information, news from pioneer migrants, advertising, media reports and perception)
What is economic migration?
The movement of population for economic gain or betterment
To obtain jobs or better paid employment
Explain factors that may limit the ability of people to migrate?
Physical - wellbeing of migrant and oceans mountains or swamps
Economic - finances to pay for migration, transport and housing costs and availability, employment
Social - family size, age, culture, level of education
Why is the scale of rural urban migration greater in LEDC than MEDC?
General cause of migration: socio economic disparity (services, opportunities and quality of life are poor in rural compared to urban)
Widespread in LEDC but applies only to certain MEDC (remote e.g. Mountains)
MEDC rural urban is in the past and more urban rural occurs now
LEDC is still dominant
Due to different stages in urbanisation
Push factors of rural urban migration in LEDC vs MEDC?
LEDC: Unemployment
Poor access to education and healthcare
Natural disasters
Lack of food security
MEDC (remote):
Limit job opportunities
Long distNcw education and healthcare
NO physical hardships or problem of food security
Pull factors of rural urban migration in LEDC vs MEDC?
Attraction of urban areas
Job opportunities
Higher wage rates
Access to better range and quality of services and shops
LEDC is more greatly improved quality of life
Define international economic migration?
The movement of people for more than a year
To another country
To seek employment
Ravensteins laws or migration:
Greatest body of migrants travel short distances
Produces currents directed at commercial centres
Each current has a counter current in the opposite direction
Urban migrated less than rural
Male migrate more over long distances
what are the three costs of migration?
Closing up
Cost of movement
Opening up
what is the closing up cost of migration?
changes to assets owned
LIC - low monetary, high personal
HIC - costs of selling house, estate agents, selling possessions that can’t be transported
generally substantial
what is the cost of movement cost of migration?
depends on mode of transport and time taken
personal transport costs and costs of transporting possessions
what is the cost of opening up cost of migration?
