Megacity Demographics Cities are growing at a rate of around 1

million people every week.

Half the Earth's population will soon live in congested, urban regions mainly in the poor, developing countries of the South.

If the 20th century was the century of

urban sprawl, the 21st century will be the century of the megacity.

Growth of Megacities in Rich and Poor Countries While the greatest megacities were

once in rich countries, they are now dominated by cities in the less developed world

Why??? Think about rural push factors and natural increase… MAJOR UNIT CONCEPTS!

Megacity Demographics The 10 largest megacities in the world as of the

year 2000 are: 1. Tokyo, Japan 26.4 million

2. Mexico City, Mexico 18.4 million 3. Bombay, India 18.1 million 4. Sao Paulo, Brazil 17.8 million 5. Shanghai, China 17.0 million 6. New York City, USA 16.6 million 7. Lagos, Nigeria 13.4 million 8. Los Angeles, USA 13.1 million 9. Calcutta, India 12.9 million 10. Buenos Aires, Argentina 12.6 million

Tokyo is the world’s largest megacity

Megacity Demographics The world's megacities take up just 2% of

the Earth's land surface, yet they account for roughly 75% of industrial wood use, 60% of human water use, and nearly 80% of all human produced carbon emissions.

These figures suggest that the struggle to achieve an environmentally sustainable economy for the 21st century will be won or lost in the world's urban areas.

Urban Hierarchy

The Opportunities of a Megacity

Megacities are vibrant centers of economic activity, social interaction and creativity.

Hubs in the global network of economic activities such as trade.

Megacities bring together people and resources and are able to generate huge amounts of wealth.

Challenges of Megacities High population concentration and density Uncontrolled spatial expansion Severe infrastructural deficits Inadequate water supply and sewage Signs of ecological strain and overload Poor housing provision Increasing disparity between rich and poor
