Urbanisation Characteristics and causes of urbanisation
Urbanisation Definition “Urbanisation is a process of urban growth which leads to a greater proportion of people being concentrated into towns and cities”
Urbanisation • In 2008 – for the first time in history over 50% of the world’s population lived in towns and cities. • Urbanisation – results in an increasing proportion of city dwellers in contrast to those in the countryside • Urbanisation is a worldwide process – it began at different times in different parts of the world and occurred at contrasting paces.
Causes of urbanisation 1. Rural to urban migration 2. Natural Increase
Rural – urban migration • Rural to urban migration – result of push and pull factors
Push and pull factors Push factors Pull factors Difficult/harsh climate – eg. droughts Chance of a better life Struggle to provide food for family Better housing and amenities Very low income Chance of good jobs – higher wages Only able to own small plots of land Children able to go to school Can’t afford to fertilizers to increase yields Better medical/health care
Natural increase • The people that migrate into towns and cities tend to be young resulting in high levels of natural increase • high % of young adults = high levels of births • Falling death rates due to improved medical care means more babies are born than people dying, further increasing the urban population
