Rural-Urban Migration & Natural Increase

The Growth of Megacities

  • A megacity is a city with a population of 10 million people or more
  • There were just 3 megacities in 1970; today, there are 34 megacities and this number is set to grow to at least 40 by 2030
  • Megacities grow as a result of rural-urban migration and natural increase  
  • The world has reached a point of hyper-urbanisation because since 2007 more than half of the world’s population live in urban areas  

megacities

Megacities (2021)

  • The main causes of rural-urban migration are categorised into urban pull factors and rural push factors
    • The main urban pull factor is employment as TNCs usually locate in urban areas offering employment opportunities that do not exist in rural areas
    • Other urban pull factors include better schools and healthcare
    • The main rural push factor is poverty which is exacerbated by population growth and a lack of jobs

Social and Environmental Challenges of Rapid Urban Growth

  • The continued growth of urban areas is inevitable which poses social and environmental challenges to these megacities

 Social and Environmental Challenges

Social Challenges

Environmental Challenges

Insufficient affordable housing

Limited accessibility to education and healthcare

Water pollution from untreated sewage

Air pollution from industry and vehicles

Loss of farmland

Exam Tip

Make sure you have examples of megacities and some specific details about at least one megacity to use in your exam.

International Migration

International Migration into Global Hubs

  • A global hub is a highly globally connected city and are sometimes known as ‘World Cities’
  • Global hubs can be found in countries at different stages of their development, for example, New York, Mumbai, London, Tokyo, Sao Paulo and Beijing
  • International migration has led to the growth of these global hubs

 Types of International Migration

Type of Migration

Description

Examples

Elite international migration

Migrants are highly skilled and/or socially influential people e.g., Actors, Bankers, Academics and Computer programmers

Wealth comes from their profession or inheritance

Many live as ‘global citizens’ with numerous homes in different countries

Many affluent Americans and Russian oligarchs live or work in the UK

Low-waged international migration

Global hubs are very attractive to these migrants

Migrants work in low pay jobs such as in kitchens, on constructions sites or as cleaners (legally and illegally)

London, Los Angeles and Dubai have many immigrants e.g., over 2 million Indians live and work in the UAE

Internal (rural-urban migration)

Main reason for urban growth in global hubs in developing and emerging economies

However, it doesn’t play a huge role in Europe or North America

Around 3 million people are moving from rural areas to urban areas in India per year

Costs & Benefits of Migration

Costs & Benefits of Migration

  • Migration increases countries’ interdependence with each other
  • There are many impacts of migration on both the source and the host country
  • The number and complexity of the impacts usually results in disagreements over whether migration is overall positive or negative

 Costs and Benefits of Migration

 

Host Country

Source Country

Benefits

Migrants can fill skills shortages

Economic migrants tend to be willing to do labouring work e.g., working on farms

Migrants pay taxes and spend their wages on rent and in shops

Some migrants may start a new business employing others

Migrant remittances contribute to national earnings

Reduced spending on healthcare and housing

Migrants, or their children, may return, bringing new knowledge and skills

Costs

Social tension is possible if people in the host country believe migration has led to less jobs or housing

Policy changes to address public concerns e.g., to reduce migration

Shortages of school places in some areas as a result of natural increase within youthful migrant communities

Reduction in the independent, working population that would have contributed to the economy

Reduced economic growth as consumption falls

Increase in the number of dependents – children and elderly
