Sessions 10 & 11: WORLD CITIES
UNIT 1: GOING GLOBAL
Learning Objectives
1. To define a world city, million city and mega city
2. To describe the causes (push and pull) of rural-urban
migration
3. Describe and explain the global pattern of megacities,
including regional variations in growth rates
Starter:
Obj 1: To define a world city, million city and mega city
Sort the cards to match definitions and examples
• World cities = A city able to have an effect on
global affairs through it’s socio-economic
resources and importance in global networks
• Million cities = Metropolitan areas with a
population in excess of 1 million inhabitants
• Mega cities = Metropolitan areas with a
population in excess of 10 million inhabitants
List of largest cities: http://www.mongabay.com/igapo/cities.htm
Identify which category the following
belong to and be ready to explain your
answer
Delhi
Brussels
Newcastle
Upon
Tyne
Identify which category the following belong to
and be ready to explain your answer
• All of these cities are million cities
• Delhi is the only ‘mega city’ (16,700,000) and has
the fastest growth rate of any megacity in the
world (4.6% per year!)
• Brussels is the ‘Capital city’ of the European
Union... Just over 1 million but an important
world city.
• Newcastle Upon Tyne is the smallest million city
in the UK, with a population of 1,100,000
Urbanisation –p114-15 blue book
Obj 2: To describe the causes (push and pull) of rural-urban migration
• What is urbanisation?
• What causes urbanisation?
(create a definition plus a table of push and pull factors)
• What is urbanisation?
Urbanisation is the increase in the proportion of people living in towns
and cities.
• What causes urbanisation?
Urbanisation occurs because people move from rural areas
(countryside) to urban areas (towns and cities). This usually occurs
when a country is still developing.
The UN predicts that by 2030 60% of the world's population will live in
urban environments.
Rural push factors
Urban pull factors
•Lack of resources to support the growing
population eg. Wood for fuel and shelter
•Lack of employment opportunities
(reliance on agriculture)
•Lack of new opportunities
•Poor infrastructure eg. Poor roads,
plumbing, telephone connections
•Lack of local healthcare/education
•Mechanisation of agriculture may mean
less need for people on the land
•Opportunities for employment (within
formal and informal sectors)
•Job opportunities in TNCs
•Perceived quality of lifestyle
•Provision of services and infrastructure
•Modern Housing
•The lure of a global hub
•Improved transport makes travel to urban
areas easier
•Opportunities presented by development
schemes
•Relaxation of migration laws
Obj 2: To describe the causes (push and pull) of rural-urban migration
• Work in pairs
• One partner read through and complete the
comparison worksheet for Los Angeles (pages
110-115 Digby et al)
• One partner read through and complete the
comparison worksheet for Mumbai (pages -121
Digby et al/p116-117 edexcel text book)
• Together agree three similarities and three
differences between the process of urbanisation
in Los Angeles and Mumbai
Obj 3: Describe and explain the global pattern of megacities,
including regional variations in growth rates
• Urbanisation is closely linked to development –
areas currently experiencing the fastest
urbanisation are NICs and LEDCs
Watch the following films.
Urbanisation lagos
Welcome to Lagos
As you watch take notes on:
 Key facts and background information
 Challenges and problems faced (video 1)
 Opportunities provided by urban living (video 2)
Describe and explain the global pattern of megacities, including regional variations in
growth rates
Urbanisation in the late 20th century
A more urban world – but how has this happened?
Urbanisation in the late 20th century
• The growth of an urban population BBC LINK
• Europe/N.America are the most urbanised regions
50’s/60’s • Rapid growth in S.America and Africa
• S.America continues to rapidly urbanise
70’s/80’s • Asia begins to urbanise at an increasing rate
90’s/00’s
/
beyond
• Urban pop in MEDCs stabilises
• Highest urban growth rates found in Asia and Africa
• Highest % increases in Africa...but volume in Asia much higher

Optional hmk:
1. Watch Andrew Marr’s Mega Cities1: Living in the City –
Available on the LRC CLICK VIEW
Make notes under the titles ‘winners’ and ‘losers’, making
notes on mini case-studies to add to your understanding of
mega-cities.
2. Watch the Lagos clips and make notes as per the slide
instructions
