      Global cities and megacities

      Lesson details

      Learning outcome

      I can explain how some cities have a global influence.

      Key learning points

      1. Global cities influence business, banking and culture around the world.
      2. Not all megacities (10 million or more) are global cities and vice versa.
      3. Global cities are hubs for international travel.
      4. Global cities are diverse and multicultural.
      5. The influence of different cities changes over time.

      Keywords

      • Megacity - a city with a population of over 10 million people

      • Global city - a city that has a major international influence, for example, on trade and travel, culture and politics (ideas)

      • Multicultural - including people with different cultures and beliefs and reflecting this diversity in a place’s food, fashion, architecture, etc.

      Common misconception

      All megacities are global cities because they are so big.

      Not all megacities are global cities. While megacities have populations of over 10 million, global cities are defined by their international influence in areas such as finance, culture, politics, and transport.

      Teacher tip

      Use well-known examples (e.g. New York, London, Lagos, Tokyo) to help students distinguish between global cities and megacities. Visuals such as maps or global company headquarters can support understanding of influence beyond just size.
