Urbanisation
Urbanisation is the growth in the proportion of a country's population that lives in urban areas.
Urbanisation is caused by rural-urban migration and a naturally increasing population.
As people migrate to cities the urban population increases.
The migrants tend to be young people looking for work.
They may then have children, which further increase the urban population.
Rural-urban migrations takes place because of push and pull factors:
Push Factors Pull Factors
Mechanisation of agriculture means fewer people There are more jobs available in urban areas
are needed to work the land so there's a lack of jobs
Changes in land use can drive people out ­ e.g. Jobs are usually better paid
farmland may be flooded when dams are built for
hydro-electric power
Natural disasters may damage homes and farmland, Better access to healthcare and education
which people cannot afford to repair or rebuild
Some farmers take out loans to help them improve Other family members may have already moved to
their yields, if their crop fails they may be unable to the city
pay these loans back
Human activity and changes in climate can cause There is often a perception that quality of life will be

Lack of services Pull of the bright lights

These included:
Agricultural revolution: loss of work and surplus of food for towns
Industrial processes: labour drawn in from countryside to work in factories
New power: coal took over from water power, mining areas expanded
Improved transport: canals then railways and later motorised roads
Improvements in medicine and hygiene: move people could live close without risk of disease

As urban populations grow there is an increased demand for space, resources and services.
If these increased demands cannot be met, it can lead to poor quality of life for the people living in the
area. Many developing countries cannot afford to meet these demands or cannot keep up with the rapid
