Özet:

It is known that countries that form organizations for international integration and cooperation, such as the European Union (EU) and the OECD, have generally similar socio-economic and political characteristics. The aim of the study is to determine whether the countries that make up the same group show similar characteristics by moving from the Better Life Index indicators. The similarities of the countries are determined by the Fuzzy Method of Collecting. As a result of the aggregation analysis, the most suitable aggregation number was determined as 2 and 4. When the group number is two, the first group is determined as the countries that are members of both the OECD, the EU and the G10. At the same time, the conclusion has been that these countries are often made up of the EU’s developed countries and the G10 countries. When the number of groups is four, the first two groups include the member countries in each of the three organizations, the recognized countries in which they develop. In the third group there are no G10 countries. In addition, it has been determined that the United States alone forms a crowd according to the life index indicators. In short, the United States has different well-being characteristics than other countries.
