Understanding Cities and Urban Change
You'll need to master several key terms that describe how cities develop. Urbanisation happens when more people move from rural areas to cities, whilst counter-urbanisation is the opposite - people leaving cities for smaller settlements.
Developing countries have low human development, emerging countries have medium to high development, and developed countries have very high human development. These classifications help explain why cities grow differently around the world.
A mega city contains over 10 million people, whilst a major city has at least 400,000 residents. The Human Development Index (HDI) measures a country's progress using life expectancy, education, and income data.
Key Point: Understanding these definitions forms the foundation for analysing urban change patterns globally.
