      Lesson details

      Learning outcome

      I can explain who lives in cities and why.

      Key learning points

      1. Urban populations often have a larger share of people aged 18–40.
      2. Migration to cities is driven by employment and educational opportunities.
      3. Cities provide a wide range of leisure facilties which are also a draw for younger people.
      4. Natural increase is a key factor in the growth of urban populations.
      5. High population density puts pressure on infrastructure and services.

      Keywords

      • Migration - the movement of people from one place to another

      • Natural increase - when birth rates are higher than death rates

      • Population density - the number of people living in a defined area, e.g. 300 people per square kilometre

      Common misconception

      Cities only grow because of migration.

      While migration is a key factor, natural increase (more births than deaths) is often just as important - especially in cities with young populations.

      Teacher tip

      Use real-life city examples (like London, Manchester, or Lagos) to illustrate why people move to cities and how different age groups use urban spaces. This helps students connect abstract ideas (like migration or population density) to places they know or have heard of.
