• Over the last 60 years, the proportion of people living in urban areas has been increasing rapidly. Just recently, it has been suggested that over half of the world’s population live in urban areas. However, the rate of growth varies and there must be reasons for this.

10 biggest cities in 1900. How does this compare to now?

•London, United Kingdom 6,480,000 people           •New York, United States 4,242,000 people           •Paris, France 3,330,000 people           •Berlin, Germany 2,707,000 people           •Chicago, United States 1,717,000 people           •Vienna, Austria 1,698,000 people           •Tokyo, Japan 1,497,000 people           •St. Petersburg, Russia 1,439,000 people           •Manchester, United Kingdom 1,435,000 people           •Philadelphia, United States 1,418,000 people

TASK 2 Complete this table using the weblink on Lionel ‘Patterns of Urban Growth’

• Almost 50% of the worlds population lives in urban areas.• 19% live in cities where the population exceeds 1 million people.• Global scale rapid urbanisation has occurred over the last 50

years.• Most urbanised continents are Europe, North America, South

America Oceania (the ‘developed’ world).• However, there are more urban dwellers in Asia (40% of

population=1.4 billion)• Also urbanisation is most rapidly increasing in Africa and Asia. By

2025 almost half the population of them will live in urban areas and 80% of all urban dwellers will live in developing countries.

• So , although MEDCs have more cities, more people actually live in cities in the developing world and this is continuing to rise.

WHAT ARE THE REASONS FOR THIS?

• Define these key words;

• Millionaire cities• Megacities• World cities

• Now make notes using the handout to explain the pattern we see on slide 10.
