Characteristics of Global Metropolises

This page presents a comprehensive world map illustrating various aspects of global metropolises.

Key features of the map:

1. Population size of agglomerations (in millions, 2020)
2. Growth rate of agglomerations (2005-2020)
3. Urbanization rate by country (2018)

Vocabulary:

• Agglomeration: A continuous urban area that may extend beyond city limits
• Urbanization rate: The percentage of a country's population living in urban areas

Highlight: The map identifies Mumbai as a case study for the chapter, indicating its significance in understanding metropolization.

Key observations:

• Largest agglomerations are found in Asia, North America, and South America
• Highest growth rates are observed in Africa and parts of Asia
• Urbanization rates vary significantly across regions

Example: The "Boswash" corridor in the northeastern United States is highlighted, showcasing a densely urbanized region stretching from Boston to Washington D.C.

This map provides a global perspective on the distribution and characteristics of major metropolises, illustrating the processus mondial différencié of urban development.

Economic Power of Metropolises

This page focuses on the economic aspects of global metropolises, presenting data on Gross Urban Product (GUP) and its growth.

Key elements:

1. GUP in billions of dollars (estimates for 2020)
2. GUP growth rates (estimates for 2005-2020)

Definition: Gross Urban Product (GUP) is the metropolitan equivalent of Gross Domestic Product (GDP) for countries, measuring the economic output of urban areas.

Example: Tokyo's GUP of $1,602 billion exceeds Mexico's GDP ($1,063 billion) and equals South Korea's GDP ($1,550 billion).

The map categorizes metropolises based on their GUP:

• Over $1,000 billion
• $500-1,000 billion
• $300-500 billion
• $100-300 billion

Growth rates are also categorized:

• Less than 2%
• 2-3%
• 3-5%
• Over 5%

Highlight: This economic data underscores the significant role of metropolises in the global economy, with some cities producing as much economic output as entire countries.

This information provides insight into the economic dimension of métropolisation, showing how urban centers become powerhouses of global economic activity.
