The movement of people from rural areas to urban areas
Settlement Hierarchies
If we group and classify a number of settlements according to their size and shape, the result is settlement hierarchy
Key characteristics of Settlement Hierarchy
The number of services that a settlement provides increases with settlement size
Small settlements will only provide low-order services such as a post office
Larger settlements and conurbations have a much larger sphere of influence than smaller ones
The range of a service or product is the maximum distance people are prepared to travel to purchase it
What is a Megacity?
An urban area with over 10 million people living there. More than two thirds of the world's megacities are located in LIDCs and EDCs. Predictions are made that by 2030 the number of megacities will increase from 28 to 41
What is a World City?
Cities that are centres for trade and business. They hold global influence. They are mostly in AC countries but more EDCs are becoming world cities; e.g. Moscow
Push Factors of Urbanisation
Natural disasters
War and Conflict
Mechanisation
Drought
Pull factors of Urbanisation
More Jobs
Better education & healthcare
Increased quality of life
Following family members
Social Consequences of Rapid Urbanisation in LIDCs
Little official housing available
Infrastructure struggles to support growingpopulation
Increase in crime rate
Economic Consequences of Rapid Urbanisation in LIDCs
May not be enough jobs - increased unemployment
Informalsector increases - little access to education and healthcare
Environmental Consequences of Rapid Urbanisation in LIDCs
Rubbish may not be collected
Sewage and toxic waste pollutes river environments
Increased congestion produces more pollution
What is Counter-Urbanisation in ACs?
This is the movement of people from city centres to the outskirts
Push factors of Counter-Urbanisation in ACs
Overcrowding and pollution
Unemployment increases
Deindustrialisation of centre
Traffic congestion increases CO2
Pull factors of Counter-Urbanisation in ACs
Greenspaces & familyfriendly
New modernhousingestates
Improved public transport
Rents cheaper on outskirts
What is suburbanisation?
This is the movement of people from city centres to the outskirts
Push factors of Suburbanisation
Overcrowding and pollution
Unemployment increases
Deindustrialisation of centre
Traffic congestion
Pull factors of Suburbanisation
Greenspaces & family friendly
New modern housing estates
Improved publictransport
Rents cheaper on outskirts
Environmental consequences of Suburbanisation
New housing damages countrysides and habitats
Increase of cars - adds to air pollution
Economic consequences of Suburbanisation
People leave centres and they become deserted
Unemploymentincreases, which leads to poverty
Social consequences of Suburbanisation
Offices and businesses are abandoned
Economic and ethnicsegregation
Push factors for Re-urbanisation in ACs
Lack of jobs in rural and suburban areas
Less leisure and entertainment in rural areas
Counter-urbanisation may have increased house prices
Pull factors for Re-urbanisation in ACs
Redevelopment of brownfieldsites with improved housing
Young people are attracted to the Universities
People are attracted to entertainment facilities available
Social consequences of Re-urbanisation
Shops and services benefit from the additional residents
Increase in tension between new and older residents
House prices in redeveloped areas increase
Schools benefit from the increase of students
More jobs and less employment within the area
Environmental consequences of Re-urbanisation
Redevelopment of brownfield sites improves old industrial and polluted areas
Decreases pressure on greenfield areas
Could destroy urban wildlife
Economic consequences of Re-urbanisation
New shops and services will improve local economy
Jobs available may not be accessible to original residents
Urban tourism may increase
What is Informal Housing?
This is housing that is built on land which does not belong to those who are building it. This may be on land that is unsuitable due to its surroundings
What is Internal Growth?
Internal growth occurs when urban areas experience rapid rates of population growth. This comes as a result of a large amount of arrival of people in cities, who are after finding a job, house and a partner will have children. This occurs mostly in LIDCs
What is a Greenbelt Area?
This is a zone of land surrounding a city where new building strictly controlled to try to prevent cities growing too much and too fast
What is a conurbation?
A conurbation is a region comprising a number of cities, large towns, and other urban areas that, though population growth have merged to form one continuous urban or industrially developed area
