A Unified Approach to Measuring Poverty and Inequality
of median in Samegrelo [8,F] is twice as large as the growth of mean per capita consumption expenditure [8,C]. The most interesting pattern can be seen for Mtskheta-Mtianeti, where the mean grows by 9.3 percent [10,C], but the median falls by 6.7 percent [10,F]. Columns G, H, and I analyze inequality within subnational regions using the Gini coefficient, which lies between 0 and 100. Although the overall Gini coefficient has increased by 0.9 [11,I], a mixed picture is found across subnational regions. In Tbilisi and Kakheti, inequality rises by 4.3 percent [2,I] and 4.0 percent [1,I], respectively. In Samtskhe-Javakheti, inequality falls by 1.8 percent [5,I], while in Kvemo Kartli and Imereti, the Gini coefficient changes by a meager 0.1 [5,I] and [9,I], going up and down, respectively. Headcount Ratio and the Distribution of Poor Table 3.9 analyzes the headcount ratio of Georgia by population subgroup, where each subgroup is classified by subnational regions—such as Kakheti, Ajara, and Imereti—which could be states or provinces. The poverty line for this table is GEL 75.4 per month (we use only one poverty line here, but the analysis could be conducted for any number of poverty lines).
