/Introducing the concept of a sphere of influence Spheres of influence dependant on activities
The sphere of influence of a city on the transport is significant. With its infrastructure, cities can pull in thousands if not millions of people a day all commuting into areas where office space and commercial activity are the main priority. This means that the city has a huge reach. There are only certain roles, activities and venues that exist in cities and are not available in wider communities. Now consider green space, where the sphere of influence for a city is reduced as those living in the suburbs are more likely to have gardens and greater green space (such as parks, fields) available to them. To demonstrate the extent of this population growth and urbanisation due to this sphere of influence, if you explore world cities’ populations plotted by Luminocity 4 you see that traditional European cities, whilst growing at a slower rate more recently, are dwarfed by the growth of cities such as Bangladesh (0.3 million in 1950, projected to be 31.2 million by 2035), Kinshasa (0.2 million in 1950, projected to be 26.7 million by 2035), Shanghai (4.3 million in 1950, projected to be 34.3 million by 2035).
