This document discusses the process of urbanization and trends in urban populations globally. It defines urbanization as an increasing proportion of a population living in towns and cities rather than rural areas. In 1950, less than 1/3 of the world lived in urban areas, but now over half do, and it is projected that 60% will by 2015. Urbanization generally occurs as countries develop economically and transition from agricultural to industrial economies. While urbanization is a global trend, it is occurring at different rates around the world, with the highest rates currently in the least developed countries in Africa and Asia. The document examines maps and graphs showing variation in urbanization levels between countries and regions.

Changing Urban Environments
What are the Characteristics of Urbanisation? Lesson 1
Lesson Objectives • All will understand what we mean by an urban area and the process of urbanisation. • Most will understand how urbanisation has varied throughout the world and over time. • Some will be able to identify, describe and compare trends from maps and graphs.
What is an urban area? • As you watch the video, write down words to describe an urban area http://www.youtube.com/watch?v=uyaj2P-dSi8
What is urbanisation? A process where an increasing proportion of the population lives in towns and cities (and consequently there is a reduction in the number of living in rural areas)
Rate of urbanisation • In 1950 fewer than one person in three lived in a town or city • Today half the world’s population live in an urban area … by 2015 the proportion will be 60% • In 1950 New York was the only global megacity …. By 2015 there will be 27 megacities …. 21 of them will be in Asia
• Urbanisation is generally linked with economic development. • As a country moves from a mainly rural agricultural economy to a more industrial, commercial economy, the population becomes increasingly concentrated in towns and cities. • Countries that have reached high levels of economic development usually have an urban population of over 75% of the total population and rates of urban growth are low.
Global Trends in Urbanisation • Urbanisation is a global process, but it is occurring at very different rates in different parts of the world • Stick the graph into your book, label it “Urban Population 1950 – 2030” • Describe the trends shown by each of the lines. Support your answer with evidence from the graph. The best answers will give evidence to support the trends you identify e.g. In 1950, The level of urbanisation in the least developed countries was only 8%. By 2050…
In which countries do you think most people live in urban areas? • Try to predict 5 countries in the world where most of the population live in urban areas, and 5 countries where a low percentage of the population do.
• Shape in your map to show differing levels of urban population in different countries. Try to label at least 3 countries with a high percentage of population in urban areas and three with a low level.
• Describe the patterns shown by the map. Try to select areas where rates are very high, average and very low. • The best answers will give general trends – is the population more urbanised in the north or the south? In Africa or Europe? Note any exceptions to the trends you identify.
Lesson Objectives • All will understand what we mean by an urban area and the process of urbanisation. • Most will understand how urbanisation has varied throughout the world and over time. • Some will be able to identify, describe and compare trends from maps and graphs.
Plenary True or false? 1. Urbanisation is the growth in the proportion of a country’s population living in urban areas 2. More than 50% of the world’s population currently live in urban areas 3. The rate of urbanisation differs between richer and poorer countries 4. More than 80% of the UK’s population live in urban areas 5. Most urbanisation is occurring in poorer countries.
