Growing urban populations • For the first time ever, the majority of the world's population lives in a city. • One hundred years ago, 2 out of every 10 people lived in an urban area. • By 1990, less than 40% of the global population lived in a city, but as of 2010, more than half of all people live in an urban area. http://www.who.int/
By 2030, 6 out of every 10 people will live in a city, and by 2050, this proportion will increase to 7 out of 10 people. • Currently, around half of all urban dwellers live in cities with between 100 000 - 500 000 people. • Fewer than 10% of urban dwellers live in megacities (defined by UN HABITAT as a city with a population of more than 10 million). • http://www.who.int/gho/urban_health/situation_trends/urban_population_growth_text/en/

Urban growth rates • Suggest some reasons for the patterns and trends
Most urbanised continents are Europe, North America, South America Oceania (the ‘developed’ world). • However, there are more urban dwellers in Asia (40% of population=1.4 billion) • Also urbanisation is most rapidly increasing in Africa and Asia. By 2025 almost half the population of them will live in urban areas and 80% of all urban dwellers will live in developing countries. • So , although MEDCs have more cities, more people actually live in cities in the developing world and this is continuing to rise. What are the reasons for this?
task • Define these key words; • Millionaire cities • Megacities • World cities .
To finish • Now look back at your image. • What annotations could you add to it using the information from today’s lesson?
