Describe the Multiplier effect
Economic growth encourages populations in cities to grow. More jobs are available due to increased demand, and more services are needed for an increasing population.
Describe population growth
Through rural-urban migration and natural increase.
Describe Economies of Scale
Where larger cities have financial savings on transport and communications for both people and businesses rather than smaller cities. This is because the distances within one megacity are less than the distances between many smaller cities.
Describe Economic development
Increase in secondary and tertiary industries leads to economic growth leading to urbanisation.
Explain TWO ways by which cities can grow in size
Multiplier effect [1]. Economic growth encourages populations growth [1]. More labour is available and more services needed for an increasing population [1].
Population growth [1]. Through rural-urban migration [1]. Through natural increase – when birth rates are higher than death rates so population rises [1].
Economic development [1]. Increase in secondary and tertiary industries leads to economic growth leading to urbanisation [1].
