MAPPING OF SOCIO-ECONOMIC OBJECTS BY MEANS OF POLAR AREA DIAGRAMS WITH AVERAGE VALUES
Abstract
A new cartographic method for the visualization of socio-economic events and objects, i.e. a polar area diagram with average values, is suggested which emphasizes the local structural peculiarities in comparison with the national or regional averages. This method is a modified circular diagram where the additional circle shows the average values of all indicators in the country, and the radius of each sector demonstrates a parity of the relative size of a particular sector with the national average. If the size is higher than the average level the radius will go outside the circle and vise versa. This is why the very asymmetry of the diagram reflects the specific features of a given object. Practical application of the method is illustrated by the investigation of the structure of Chinese Diaspora in the USA.
