Growth of Urban Areas

Rank-Size Rule • Defined: the country’s nth-largest settlement is 1/n the population of the largest settlement • In other words – the second largest city is ½ the size of the largest

Primate City The leading city of a country. The city is disproportionately larger than the rest of the cities in the country. (Some books define as – The largest city…) For example: London, UK Mexico City, Mexico Paris, France - the rank-size rule does not work for a country with a primate city

World Cities

Megacities • Large cities characterized by both primacy and a high degree of centrality within their national economy – population of 10 million+ • UN anticipates by 2015 – 22 cities of 10 mil. + – With some cities at 25 mil. + – Fastest growing cities are not in core regions Map of megacities- Fellman, 370

Megacities examples • • Bangkok Beijing Cairo Kolkata (Calcutta) Dhaka Jakarta Lagos • • • Manila Mexico City New Delhi Sao Paulo Shanghai Tehran

• Overurbanization – cities grow more rapidly than the jobs and housing they can sustain. Leading to – Instant slums, open sewers, no basic utilities – Squatter settlements • • • Chile – callampas (mushroom cities) Turkey – gecekondu (built after dusk and before dawn) India – bustees Tunisia – gourbevilles Brazil – favelas (a wildflower that live on the hillsides over Brazil) • Argentina – villas miserias • Peru - barriadas • Addis Ababa, Ethiopia – 80% of pop. are homeless or live in unfit housing
