Urbansiation 1) an increase in the absolute number of people living in urban areas 2) The movement of people into urban areas 3) the expansion of urban areas into the surrounding countryside 4) an increase in the proportion of a population living in towns and cities in a country Objective: To be able to explain the processes taking place in urban areas Centripetal or Centrifugal? Push and pull factors causing inward and outward movement of populations Urbanisation creates wealth This can help to explain peoples choice of movement Urban p287 course companion Push factorsPull factors Centripetal Forces These are associated with the movement of people into the urban area. For each of the following centripetal forces, explain the process that encourages this inward movement. Urbanisation Reurbanisation / urban renewal Centripetal Forces Rural to urban migration Stepwise Migration Model Behavioral Model that migration occur in stages with a wave-like motion. Major settlements tend to attract migrants from smaller cities, which attract. M igrants from smaller towns and villages Lees Migration Model Centripetal Rural urban migration Urbanisation Gentrification Urban renwal Gentrification Urban renewal Use the images to annotate with definitions Use p286 course companion Centrifugal Forces Urban sprawl Suburbanisation Counter-urbanisation Family life cycle Intra urban population movement occurs within the city and may involve shifts of population during the family life cycle. People move around different zones of the city depending on their age and need for a house of a certain size. P290 fig 11.8 course companion Task Suggest why processes of population movement are likely to vary between cities. In other words why do some cities see centripetal movement, and others see centrifugal movement? Use any examples you know to backup your points. Is there a link between natural increase in the population size, and the number of urban areas? Firstly, discuss what factors might influence a country to have a high (or low) natural increase in its population size. Then consider what indicators you could use to exemplify this. Finally, try to find a graphic that shows the link between natural increase and urban populations. GENERAL PATTERN? SO, WHAT IS A DRIVING INFLUENCE IN THE GROWTH OF GLOBAL CITIES? Link it all together Look at some of the reasons why cities began to expand and spring up around the world, from 1955 onwards. What were the driving forces? This is the Spec (remember?)
