The zone of influence or ‘Umland’ is an important term to express the inter-connection between the town and its surrounding rural settlements. The town in itself is not a self-sufficient unit but has to rely upon the surrounding rural areas for the supply of various essential supplies and raw materials. This interrelation is a key concept in urban geography. A town or city acts as a service centre for adjoining rural areas. Umland or zone of influence is an important indicator to understand the economic impact of towns or cities on their adjoining rural areas. There are two approaches to identify the umland of a city quantitative and a qualitative approach. In the qualitative approach, various service indicators are taken to identify umland, for example.
