Examination of Consumption Expenditure Distribution among NUTS-2 Regions in 2007-2018 with GINI Coefficient

Abstract

In this study, the distribution of 12 main expenditure categories included in the consumer price index (CPI) among NUTS-2 (Nomenclature of Territorial Units for Statistics-2) regions is examined. The study covers the years 2007-2018. In the study, interregional consumption expenditure rates are identified with the Gini coefficient, which is a measure of inequality and the obtained consumption expenditure rates through the years are interpreted. The coefficients calculated for each expenditure category are important in terms of revealing the course of consumption behavior of households in Turkey over the years and reflecting the best and worst distribution at the NUTS-2 level. Findings regarding the expenditure categories show that the consumption behavior in Turkey in the relevant period is far from equal at the regional level. According to the findings, the expenditure category with the highest inequality at the NUTS-2 level is the food and non-alcoholic beverages category with an average Gini coefficient of 0.3031. The expenditure category with the highest equal distribution, on the other hand, is the education category with a Gini coefficient of 0.2307 according to the findings.
