Inequality in social, physical, economic aspects beside with infrastructure provision has become a widespread attribute between the districts in Bangladesh. Unequal distribution of facilities causes disparity among the regions. This happens due to many social, political and geographical matters. By calculating the amount of disparity it becomes helpful for the policy and decision makers to take the right action to develop the under privileged regions. The main objectives of this study are to analyze and find out inter regional disparities in the distribution of facilities and to compare the regional distribution of facilities with respect to national. In this study, interregional inequalities have been determined by using Lorenz curve and Gini index. The study investigates, existing inequality level based on facilities (Utility, Educational, Social welfare, Transport and Health facilities) in 64 districts of Bangladesh using 2011 Bangladesh Bureau of Statistics (BBS) data. With the help of these methods as well as analysis the actual scenario of disparity will be found out which in turn assist for the development of the deprived regions. The study results that there exist regional disparity in the sense of facility distribution and some leading factors tend to accelerate these inequalities.
