You will watch this YouTube once and then in groups you will try to summarise the key ideas in 1 minute. So, pay attention, make notes and prepare to explain what you have learnt.
Larger settlements and conurbations have a much larger sphere of influence than smaller ones. This means they attract people from a wider area because of the facilities they offer. Cities such as London have a global sphere of influence, whereas a small hamlet or village may only have a sphere of influence of a couple of kilometres.
Amount of people living in a settlement is not always a good way of determining the hierarchy of a settlement. Sometimes, the types of services that are found in a settlement can determine its hierarchy.

Central Place Theory:
This is related to the sphere of influence any settlement has. If you look at the diagrams you can see that a village will have a small sphere of influence and a city will have a large sphere of influence. Theoretically the services that are found in a city such as an international airport, government offices, etc need a threshold population to sustain them and so you can not have two cities inside the same sphere of influence. However, smaller settlements such as towns and villages only have services that require a smaller threshold population and therefore can be found in the sphere of influence of a city.
