Economic, Social & Political Influences
Economic
Some of the biggest growth regions in the UK, have grown as a result of the excellent economic conditions.
A poorly developed economy is often unable to support large populations and people end up living in poor housing (e.g. Brazil).
Social
Areas will have a high population density if they are located close to good communications links.
If links between cities and towns are poor, then areas will have a low population density.
Access to resources is also vital to the density of a population as people will locate in areas where they have access to the appropriate resources.
People will also often locate in an area where the culture is not to different from their own, as language barriers are often something which people are keen to avoid.
Political
Areas that receive a large level of investment often have high population densities.
Rural areas often have very little investment and therefore become run down and have low population densities.
