3.1 - Rates of Urbanisation Flashcards
How has the growth of megacities changed from 1950 to 2014?
In 1950, the biggest and most influential cities were largely in developed countries. They consisted of 2 - Tokyo and New York. By 2014 there were 28 megacities and it is still increasing - it’s predicted to rise to 41 megacities by 2030.
What is a megacity?
A megacity is a city that has a population of over 10 million people. In 2014, there were 28 and by 2030, there will be 41 megacities.
Why is London classified as a mega city?
Because even though London’s population is 8.6 million, the built up nature of the city’s suburbs means it is classified as a mega city.
A world city that plays a disproportionate role in world affairs is what? Give a full example.
It is called an alpha ++ city and an example of this is London, that like New York, have the biggest financial centres (1/2 of the world’s money come through London each year!
Compare the rates of urbanisation in the past (up to 1980) present and future.
Developing regions (Asia and Africa) have risen in urban population the most (27.5% approx). On the other hand, more developed regions Latin America have increased less than Asia and Africa, but by a small margin (27.5% vs 25%).
Describe the pattern of megacities between 2014 and 2015.
In 2014, the majority are in Asia (13) and there is a high chance that it will have the highest number of megacities by 2030.
Also the most rapid growth of megacities will be in mainly countries like India (emerging) and Malawi (developing).
In South America there is a possibility that there will be a faster rate of growth of megacities than North America.
What is urban primacy?
It is when one city dominates the country it’s in.
Suggest why urbanisation is happening faster in poorer countries.
Because as their number of doctors per 1000 is low, this leads to malnutrition, therefore not fit enough to attend to education, causing death rate and therefore higher maternal rates, increasing the population. It then increases due to urban-rural migration.
What is urabnisation?
Means a rise in the percentage of people living in urban areas, compared to rural areas.
OR
Urbanisation is the growth in the PROPORTION of a country’s population living in urban areas.
Why is India’s global influence increasing?
Because as it develops India is playing a larger role in both regional and global politics. Recently the Indian government has improved relations with its immediate neighbours like ASEAN. If this progresses, a megacity can form inside it in 2030 or 2020.
What even caused megacities to be built? Why has this happened?
This is due to an increase in urbanisation which happens due to more people, who mostly live in developing countries, move in to seek a better quality of life
Which areas of the world (continents and emerging/developing/developed countries) had the
highest level and rate of urbanisation from 1980 to 2010?
In general, the fastest rates of urbanisation in the past , are in developing countries.
How has the level and rate of urbanisation changed around the world from 2010 to 2020?
W
How will the level and rate of urbanisation change in the future 2020 onwards?
By 2050, the majority of people in every global region are predicted to live in urban areas.
How has the number and location of megacities changed over time? Where are they now and where has the greatest growth occurred?
In the past, 1980, most of the megacities were located in high income countries (developed countries) such as New York, Tokyo, Paris and London. But now, even though the average populations haven’t changed since, there has been an increase in the numbers of megacities, particularly in the emerging countries; the greatest growth has occurred there. For example in 2015 only 25% of the world’s megacities were in high income countries. The rest were in emerging countries, e.g. Sao Paulo, Shanghai, and Mumbai.
