Megacities are all different. This is due to a number of different reasons;
1. DevelopmentMany of Asia's cities are centres of wealth, Africa’s centres of poverty.
2. MigrantSome skilled, entrepreneurial and young whilst some are poorer, older and forced to migrate.
3. Growth characteristicsCity growth by natural increase or migration?
4. Planning Asian cities planned, African unplanned (lack of planners and overwhelming poverty)
5. Rate of Population GrowthVaries; 2-4% in Latin America, 4-8% in African and Asian cities.
6. Urban Processes Different processes occurring in different cities. …

Urban Processes
a) Urban growth – physical growth of cities. b) Urban Sprawl – uncontrollable growth of cities into
surrounding rural land.c) Suburbanisation (LEDC cities) – when wealthy live often in
gated communities to escape crime, poverty and pollution from the CBD. Common in South Africa.
d) Counter Urbanisation (MEDC cities) – movement of people out of city to rural area.
e) Reurbanisation (MEDC cities) – Attempts to regenerate cities, especially in Asian cities.
All of these processes are linked to the cycle of urbanisation; Contrasting Megacities

Reasons for the growth of London suburbs
1. TransportFor suburbs to develop excellent transport networks are needed. The
underground, overland trains, buses and now even bike hire means that it is easy to get from the suburbs into the city centre. In London the average commute is 40mins. Video here
2. Increasing Wealth Increase in service sector meant increase in wealth. Therefore more people
owned homes and wanted a larger one for family in the suburbs.
3. Households There has been an increase in the size and number of households as more
young people marry later. Older people living longer, occupying larger houses for longer.

authorities to build new social housing schemes (council housing).
