Takeaways

• 🌆 Urbanization and urban growth are not the same. Urban growth refers to the physical expansion of a city, while urbanization is the process where the city's population grows faster than the rural population.
• 🏙️ A country is considered urbanized when more than 50% of its population lives in cities.
• 🏭 The concept of large cities is a result of the Industrial Revolution, which intensified among the wealthy in the 19th century and the emerging poor in the 20th century.
• 🚜 Rural exodus, or the migration from rural to urban areas, is often driven by poor rural conditions and the promise of a better life in cities, which started in Brazil from the 1930s.
• 🌐 Cities have different configurations, including metropolises, metropolitan regions, conurbations, and megacities.
• 🌉 Metropolitan regions consist of a metropolis and its surrounding satellite cities, which grow in the orbit of the larger city and form intense flows.
• 🔗 Conurbations are the physical merging of cities, where the boundaries between cities become indistinguishable.
• 🏙️ Megacities are extremely large urban areas with more than 10 million inhabitants.
• 📈 The number of megacities has grown rapidly, jumping from three to 27 in just three decades.
• 🌐 Megalopolises are extensive urban areas formed by the physical merging of two or more metropolitan areas or regions, like the BOSWASH in the Northeastern United States.
