Q

Explain why most of the future growth of cities is likely to be in the developing world. (4 marks)

A
  • Cities in developing countries are growing much faster than cities in developed countries.
  • In developing countries, the urban population is growing as of natural increase - the birth rate is higher than the death rate
  • There is also RUM (Rural to Urban migration)
  • Many people are moving to the cities as agricultural practices are becoming more mechanised and there are fewer jobs, so people move to cities for work.
  • Drought or other natural disasters may also force a move.
  • Generally, urban areas provide people with better living conditions, such as piped water, electricity and healthcare, and higher wages.

Q

What are the growth rates of megacities?

A
  • In 1950 there were only two megacities: New York and Tokyo
  • By 1985 there were nine
  • Megacities in developing and emerging countries are growing very fast
  • E.g. Mumbai’s population doubled in size between 1991 and 2013. Growth rates are fuelled by RUM

Q

Explain two reasons why urban primacy can become a problem for developing and emerging countries. (4 marks)

A
  • The main problem of excessive urban primacy is that all economic growth is concentrated in the city while the city’s hinterland is deprived of growth.
  • A second problem is that political power also becomes focused in the city. Decision making that affects the whole country takes place in the primate city and is skewed toward the city’s needs, not the country’s.

Q

In 2015, London had a population of 8.6 million. Calculate the percentage increase required for London to become a megacity. Round your answer up to 1 d.p.

A 
16.3%
percentage increase:
 - difference between 2 values
- divide by original value 
- multiply by 100

Q

International migration

A

When people move to live in another country

17
Q

Internal migration

A

When people move from one part of a country to live somewhere else within that same country

18
Q

Natural increase

A

The difference between the number of births and deaths in a year

19
Q

How do cities grow (or decline)?

A

2 main ways:

  • migration - people move to live in the city, or move away from the city
  • natural increase
  • these two processes are connected - it is usually young people who migrate to live in cities, and so the birth rate for young people is higher than the death rate for old people
20
Q

What is the main cause of rapid urbanisation in emerging ans developing countries?

A

Rural-Urban migration

21
Q

Why does economic development create a multiplier effect?

A
  • economic growth means people move to the city
  • more people = bigger workforce so more industries
  • more industries = more jobs
  • more people = more customers
  • more people = more houses to be built
22
Q

What are the disadvantages of living in rural areas?

A
  • few opportunities
  • poor healthcare
  • low pay, difficult work
  • low level of education
23
Q

What are the advantages of living in urban areas?

A
  • many more jobs
  • better paid
  • better education
  • better healthcare
  • better housing
  • modern lifestyle
  • many more opportunities
24
Q

Explain two reasons why economic changes can cause a city to decline in population. (4 marks)

A
  • Economic problems can mean that industries shut down. If it is no longer easy to get a job in a city, people will move away.
  • City governments rely on taxes from businesses and residents to make the city a pleasant, safe place to live and work. If economic problems mean that tax payments go down, the city starts to become run-down, crime rates rise and more people move away.
25
Q

In 2015 London’s population reached 8.6 million - the same size it was in 1939. Suggest one reason why London’s population declined after 1939 and one reason why it has grown again. (2 marks)

A

Reasons for decline:

  • economic changes due to there being fewer jobs in London (1) (you might have put damage from WW2, but that actually wasn’t a major factor).
  • Heavy industry in London declined, jobs moved out to the suburbs and London’s port became less important.

Reasons for growth:

  • economic changes that meant there was a lot more work in London (1).
  • The main driver of this growth was the boom in London’s financial services.
  • Redevelopment of areas like London’s East End (the old dock areas) was important too.
26
Q

Formal employment

A

Jobs that pay taxes and provide workers with job security and legal protection (e.g. Health and Safety laws). These jobs are hard to get in developing countries.

27
Q

Informal employment

A

Jobs that are not regulated: informal workers pay no taxes but are not protected by law. These jobs are easy for new arrivals in a city to get.

28
Q

Working conditions

A

In emerging and developing countries there may be unsafe, stressful or uncomfortable working conditions (e.g. hot, polluted); long working hours without enough breaks; harsh penalties for lateness or absence.

29
Q

What are the urban economies and working conditions of emerging countries like?

A
  • much more manufacturing than in urban economies of most developed countries.
  • working conditions are tougher than in developed countries.
30
Q

What do economic sectors of developed countries consist of?

A
  • often dominated by services, including tourism
31
Q

State one advantage of informal employment in cities in developing countries. (1 mark)

A

1 mark each:

  • new arrivals (migrants) to the city are able able to support themselves
  • doesn’t require skills / education qualifications which means rural migrants are not excluded
  • informal workers may learn skills that they can later use in formal employment
  • easy to start - no need for premises, and rents and overheads are low
  • flexible - if one member of a family has started an informal business, other family members can join
32
Q

Urbanisation

A

An increase in the number of people living in cities

33
Q

Suburbanisation

A

The movement of people, industry and jobs from the centre of the city to its outer areas

34
Q

Counter-urbanisation

A

The movement of people out of the cities into the countryside (developed world process)

35
Q

Regeneration

A

New investment into old, run-down parts of the city (often inner city areas)

36
Q

What are the theories of city development over time?

A

1- The CBD is located where the city first developed, where all the major roads join
2- A manufacturing zone develops
3- New migrants live in this inner city zone, where housing is poor but cheap and they are close to their jobs
4- Developing public transport lets richer people live further out, in the pleasant suburbs
5- The city gets too congested for industry, which moves out to cheaper land in the suburbs
6- The inner city areas get poorer
7- As the city expands, commuter journeys from the outer suburbs become very long. Some wealthier residents move back to the inner city and redevelop the old housing
