    • High population size.

    • High population density.

    • Built-up area.

    • Administrative functions for the larger country.

Activity: What Makes a City Unique?

  • Through this activity, you will be able to describe the characteristics of cities, which include:

    • High population size.

    • High population density.

    • Built-up area.

    • Administrative functions.

Definition and Statistics of Cities

  • Definition:

    • A city is defined as a large settlement within a country.

  • Current Statistics:

    • 56% of the world’s population reside in urban areas today.

    • UN estimates suggest that this percentage could rise to 68% by 2050.

    • Notably, 2007 marked the year urban populations exceeded rural populations.

Features of Cities

  1. High Population Size:

    • Indicates a large number of inhabitants in urban areas.

    • Comparison made with rural settings.

    • Different countries have varying criteria for what constitutes a city:

      • Japanese cities: At least 50,000 inhabitants.

      • Chinese cities: At least 100,000 inhabitants.

    • Urban population growth is often attributed to:

      • High birth rates.

      • High migration rates.

    • Trivia: The largest cities are referred to as megacities, with populations exceeding 10 million.

  2. High Population Density:

    • Defined as the measure of population per unit area.

    • Urban areas display higher population densities when compared to rural regions.

    • Highest population density cities tend to have smaller land areas.

    • Formula for Population Density:
      ext{Population Density} = rac{ ext{No. of people living in an area}}{ ext{Land area}}

  3. Built-Up Area:

    • Cities comprise built-up areas indicating the concentration of infrastructures such as:

      • Roads.

      • Buildings.

      • Residential areas.

    • Infrastructure includes basic services such as:

      • Water supply.

      • Electricity.

      • Sanitation.

      • Telecommunications.

      • Transport systems.

  4. Wide Range of Functions:

    • Cities serve multiple functions and accommodate various activities:

      • Administrative Functions: e.g., government offices.

      • Commercial Functions: e.g., businesses, shops.

      • Educational Functions: e.g., universities, colleges.

      • Industrial Functions: e.g., manufacturing plants.

    • Each city's function may vary based on its resources and situational context.

    • Example: Jakarta, capital of Indonesia, hosts the Office of the President and has many industrial factories.

Task 1: Migration Motivation

  • Examine images that depict reasons why individuals decide to leave rural areas for urban centers.

Task 2: Rural vs. Urban Benefits

  • Discuss why rural living still persists despite urban advantages.

Urban & Rural Relationship

  • Interdependent Relationship:

    • Urban areas and rural areas share connections through movement of:

    • People.

    • Goods.

    • Services.

  • Comparative Characteristics:

    • Rural areas have lower population size and density.

    • Cities are more built-up with a wider range of functions.

Benefits to Urban Areas

  1. Food Supply and Resources:

    • Cities rely on rural areas for food and materials due to:

      • Limited space in urban environments for agriculture.

      • Predominantly engaged in secondary, tertiary, and quaternary industries.

      • Rural farmers supply animals and crops to urban markets.

  2. Supply of Labour/Manpower:

    • Economic activities in cities thrive supported by:

      • Developed infrastructures.

      • Availability of services.

    • Examples:

      • Construction workers for infrastructure development.

      • Teachers for educational institutions.

Benefits to Rural Areas

  1. Income from Sale of Food and Raw Materials:

    • Rural producers exchange goods for income through sales in urban areas.

    • Example: Singapore imports over 50% of its eggs and significant amounts of fruits and vegetables from Malaysian farms.

  2. Educational and Employment Opportunities:

    • Urban centers provide various educational institutions (e.g., universities, vocational schools).

    • Urban employment opportunities lead to better qualifications and hence higher income potential.

  3. Provision of Goods and Services:

    • Cities facilitate the availability of goods previously absent in rural areas.

    • Services include specialized health care not always found in rural settings.

    • Amenities, such as shopping malls, offer unique products to rural visitors.

  4. Technological Innovation:

    • Urban areas are hubs for technological developments involving scientists, entrepreneurs, and designers.

    • Examples include:

      • Installation of solar panels in urban residential areas.

      • Utilization of AI in agriculture to improve yields and efficiency.

      • Development of electric vehicles to minimize pollution.

Conclusion: What are Cities?

  • Urban Areas consist of characteristics such as:

    • High population size.

    • High population density.

    • Built-up area.

    • Wide range of functions.

  • Benefits to Urban Areas:

    • Food, raw materials, and workforce from rural areas.

  • Benefits to Rural Areas:

    • Income from sales, access to goods, services, educational and employment opportunities, and advancement in technology.
