Many social and economic variables are used as indicators of the level of development of countries. To determine the level of social and economic development, many criteria were studied in the fields of education, culture, health, and economy. This chapter analyzes 13 European Union countries that participated in the fifth and sixth enlargement process and Turkey, whose ongoing process of accession to the European Union is determined by using socio-economic indicators. Reference Ideal Method (RIM) is a new Multi Criteria Decision Making (MCDM) method. This method differentiates itself from other methods frequently used in literature by using the ideal points or ideal ranges. The chapter shows Turkey must improve socio-economic indicators to be close to the countries in the fifth and sixth waves of enlargement process of European Union.

Macroeconomic indicators are used to evaluate the current performance and forecast the future state of the economy. Within the scope of the chapter; macroeconomic indicators such as GDP per capita, unemployment, inflation, real interest rates, and growth rates constitute the criteria of Multi-Criteria Decision Making (MCDM) model. The European Union (EU) countries and Turkey are the alternatives of the MCDM problem. Best Worst Method (BWM) is an MCDM method developed by Jafar Rezaei in 2015. In this method, the decision-maker identifies only the best and worst criteria and compares them with the remaining criteria. In this chapter, the macroeconomic indicators of Turkey and EU countries analyzed by BWM. As a result of the study, Luxembourg ranks first, Denmark second, and Sweden third. The last three countries are Portugal, Croatia, and Greece. Turkey ranks 24th.
