孟加拉国人口分布研究

孟加拉国各省、区的人口分布存在着不均衡的特点,采取定量分析的方法,选取人口密度指数、胡佛指数和非均质性指数(index of concentration,Hoover’s index and in-homogeneity index)指标来分析孟加拉国人口分布现有的不平等程度和非均质性。研究结果表明,孟加拉国各省、区的人口集中都存在增加的趋势。同时,通过对斯皮尔曼等级相关系数(Spearman’s rank correlation coefficient)的计算,分析孟加拉国的各地区土地面积和人口密度的关系,发现二者之间存在着较大的负相关关系。

Study on Population Distribution in Bangladesh

In Bangladesh,population is not equally distributed in all divisions and in all districts.In this paper,attempts have been made to examine the degree of existing inequality and in-homogeneity of population distribution in Bangladesh by measuring index of concentration,Hoover's index and in-homogeneity index.By calculating those indices,it has been found that there exist increasing tendency of population concentration both in division wise and in district wise in Bangladesh.Another attempt has been made,in this paper,to examine the relationship between area shared and population density of various areal units of Bangladesh by calculating Spearman's rank correlation coefficient.There exists fair negative correlation between area shared and population density in Bangladesh.
