Urbanization
High School
Definition
The increasing concentration of people in cities and the outward growth of urban areas. Driven by migration and economic change, urbanization brings opportunities but also challenges such as housing, transport, and pollution.
Worked examples
London in the 1800s grew from 1 million to over 6 million people as factories drew workers from rural areas.
Industrial Revolution urbanization: economic change pulled migrants to cities for jobs.
Shanghai expanded from a trading port to a megacity of 25+ million, with suburbs spreading outward for decades.
Modern urbanization combines population concentration and physical outward growth of the urban area.
Common mistakes
- Urbanization only means cities getting more crowded. → Urbanization includes both population concentration and outward physical expansion of urban areas. The definition covers migration to cities and the sprawl of suburbs and infrastructure.
- Urbanization is always good because it brings economic opportunities. → Urbanization brings opportunities but also challenges like housing shortages, traffic, and pollution. The process has trade-offs; recognize both benefits and problems.
Where you'll use it next
You'll apply urbanization when studying industrial and modern economic development, population geography, environmental issues like air quality, and urban planning policies in geography and economics courses.
