What is urbanisation?
- The growth in the proportion of a country’s population living in urban areas
- more than 50% of the world’s population currently live in urban areas
Describe the settlement hierarchy
- conurbation (top)
- city
- large town
- small town
- village
- hamlet
- isolated dweling or farm
Describe ACs
- more economically developed
e.g. UK, Japan, Germany - urbanisation happened earlier in ACs
e.g. during the Industrial Revolution - slow rates of urban growth
- people desiring a better quality of life are moving away from overcrowded cities to rural areas
- good transport & communication networks means people can live in rural areas an commute to cities or work from home
Describe LIDCs
- less economically developed
e.g. Ethiopia, Nepal - not many of the population live in urban areas
- fastest rates of urbanisation
Describe EDCs
- economic development is increasing
e.g. Brazil, China, Russia
Percent of population living in urban areas varies
Describe a megacity
- an urban area with over 10 million people living there
- can be a single city or a conurbation (where neighbouring towns and cities have spread and merged together)
Describe a world city
- a city that has an influence over the whole world
- are centres for trade and businesses
- hubs of culture and science, with international media centres
What are the characteristics of a world city?
- headquarters of multinational companies based in the city
- centre for innovation in business
- major centre for manufactering
- financial services; home of an important stock exchange or major banks
- regional importance compared with other cities
- highly rated unis, often specialising in research, link to a high quality of healthcare provision
- cultrual opportunities, including opera and cinema
How has the number of megacities changed over time?
- in 1950 only 2 megacities : NY and Tokyo
- by 2014, 28 mega cities
- predicted 41 in 2030
How has the number of world cities changed over time?
- 1950 only Paris, London, Tokyo and NY
- number of world cities has increased
What is rural-urban migration?
- the movement of people from the countryside to the cities
- rapid urbanisation in LIDCs is being caused by a combination of push and pull factors
What is a push factor?
- things that encourage people to leave an area
What is a pull factor?
- things that encourage people to move to an area
What are the push factors for rural-urban migration?
- natural disasters can damage property and farmland which people can’t afford to repair
- mechanisation of agricultural equipment - farms require fewer workers so there’s fewer job
- drought can make land unproductive so people can no longer support themselves
- conflict or war can cause people to flee their homes
What are the pull factors for rural-urban migration?
- there are more jobs in urban areas that are often better paid
- access to better health care and education
- to join other family members
- better quality of life
What is internal growth?
- when the birth rate is higher than the death right
How does internal growth cause urbanisation?
- birth rate tends to be higher in cities because young people move to urban areas
- these people have children in the cities - increasing the urban population
- in LIDCs, better healthcare can be found in cities, meaning people living in urban areas live longer
- reducing death rates and increasing the proportion of people in urban areas
What are the economic consequences of rapid urbanisation?
- not enough jobs for everyone, leading to high levels of unemployment
- lots of people work in the informal sector, where jobs aren’t taxed or regulated by the government
- people often work long hours in dangerous conditions for little pay
- may not have access to education so they are unable to develop skills needed to get a better job
What are the social consequences of rapid urbanisation?
- aren’t enough houses for everyone - many people end up in squatter settlements that are badly built and overcrowded
- infrastructure can’t be built fast enough - people often don’t have access to basic services causing poor health
e.g. clean water, proper sewers or electricity - high levels of crime
What are the environmental consequences of rapid urbanisation?
- waste disposal services, sewage systems and environmental regulations for factories can’t keep pace
- rubbish often isn’t collected or it may end up in big rubbish heaps
- can damage the environment
- sewage and toxic chemicals can get into rivers, harming wildlife
- the road system may not be able to cope with all the vehicles
- congestion causes increased greenhouse gas emissions and air pollution
What is suburbanisation?
- the movement of people from city centres to the outskirts
What are the push factors for suburbanisation?
- urban areas can be overcrowded, polluted, have high crime rates, little green space
- quality of life lower
- government often clear low quality city centre housing and provide new houses outside the city
e.g. 1950-1970 slum clearances in England - deindustrialisation in city centre leads to people having to leave cities in search of employment in new industrial areas
- unemployment increases, therefore less money to spend, so local shops and services may be forced to close
- fewer local services for people living in the city centre
What are the pull factors for suburbanisation?
- lower population density in suburban areas - more open green space, safer, family friendly
- planning laws may be more relaxed, easier to build houses
- developers build new housing estates on the edges of urban areas, offering large modern houses with gardens
- improvements in public transport and increasing car ownership means people can live in suburbs and commute to work
- rents are cheaper, which attracts business
- jobs and services become available in suburbs, encouraging people to live there
What are the economic consequences of suburbanisation?
- fewer people living in inner city areas, and part of cities that are mainly offices can be deserted after work hours
- shops, restaurants and other amenities may struggle for customers and close
- as businesses leave, unemployment increases
- leads to lower living standards and poverty
