Evaluation of OECD Countries in Terms of Better Life Index According to Bulut Index

Background: The "Better Life Index", first developed by the Organization for Economic Co-operation and Development (OECD) in 2011, includes many criteria from the functioning of public services to environmental wealth, from security services to individual and social well-being. Method: The performances of OECD countries according to the decision criteria that constitute the Better Life Index has been evaluated with Bulut Index (BI) method, which is a multi-criteria decision-making method. Normalized Maximum Values (NMV) method, one of the objective weighting methods, was used to determine weights of decision criteria. Findings: Among the indicators of the Better Life Index, the murder rate per 100 thousand population ranks first in terms of criterion weight. In the study, due to the analysis and evaluation made with Bulut Index, Switzerland ranked first among OECD countries with 82.28 points in the welfare and well-being index ranking. On the other hand, Türkiye ranked fourth from the bottom among OECD countries. Conclusion: Based on the findings of the study, it is recommended that urgent and necessary measures be taken on homicide rates, long-term unemployment rates and air pollution criteria. The lack of criteria regarding civic participation, work-life balance and income status constitute limitations of the study. In future studies, it is especially recommended that other researchers include these variables.
