REGIONAL ANALYSIS OF POVERTY LINE BASED ON INCOME USING PURCHASING POWER PARITY THROUGH STATISTICAL METHODS: AN EXAMPLE OF TURKEY FOR THE YEARS 2014-2021

Abstract

Purchasing power and the poverty line are different concepts, however, they are interrelated subjects. A comparison of purchasing power and the poverty line for Turkey can be made using statistical methods. The data used in this study are based on the Income and Living Conditions Survey, which was initiated by the Turkish Statistical Institute in 2006, and stratified, multistage, and cluster sampling methods, which are probability sampling methods, were used when collecting these data. The study initially examined the changes in the number of poor people and the poverty line, based on the fixed index method, taking 2014 as the base year, for the years 2014-2021. Subsequently, changes in the number of poor people and the poverty line were calculated for the same years using the variable index method. As the method used is based on the logic of the variable basis, the results were obtained by considering each calculated year as the base compared to the previous year. The findings obtained related to the considered period were presented with the help of graphs and tables.
