The Swedish Agency for Growth Policy Analysis has developed a tool for measuring and analysing accessibility to urban areas, service and labour markets, which are important for people and businesses to be able to live and operate within a geographic area. 

The strength of the model is that, independently of geographical boundaries and working with different sizes of urban areas, you can ”put reality on the map” and thereby provide a quick overview of how a certain area looks like in terms of, for example, population and access to different kinds of service.
