The comprehensive evaluation and spatial analysis of Jiangsu´s population quality

Population quality is an integrated performance of the population´s physical fitness, cultural and scientific quality, and ideological moral quality in a nation or a region. The population quality of Jiangsu varies from one area to another with the differences in history and resource endowment, economic development level and geographical conditions. This paper uses the SPSS (Statistical Product and Service Solutions) software to construct the evaluation index system of population quality and decides the factors related to population quality with PCA (Principal Component Analysis) method; then calculates every factor score and gets the population integrated index; finally categorizes the related factors and population integrated evaluation indexes with SPSS clustering method, and makes evaluation graphics of integrated population quality of Jiangsu with ArcGIS software. The spatial distribution characteristics of Jiangsu´s population quality can be seen from these graphics. Some suggestion is presented in order to further improve the population quality of Jiangsu in the future.
