The Better Life Index analyses 11 topics that the OECD has identified as essential to wellbeing in terms of material living conditions (housing, income, jobs) and quality of life (community, education, environment, governance, health, life satisfaction, safety and work-life balance). It then allows users to interact with the findings and rate the topics against each other to construct different rankings of wellbeing depending on which topic is weighted more heavily. Life satisfaction is a measure of how people evaluate the entirety of their life and not simply their feelings at the time of the survey. The OECD study asks people to rate their own life satisfaction on a scale of 0 to 10. The ranking covers the organization’s 34 member countries plus Brazil and Russia. Costa Rica leads the 2012 HPI ranking, with particularly high scores for life expectancy and wellbeing. Vietnam and Colombia follow in second and third place. Developed nations such as the United States and the European Union member countries tend to score high on life expectancy, medium-to-high in wellbeing, but rather low on their ecological footprint, which puts them in the ranking’s second-tier. Denmark places first in the 2012 OECD Life Satisfaction survey, followed closely by Norway. Countries from Northern and Central Europe (such as Austria, the Netherlands Switzerland and Finland) dominate the top part of the ranking. At the bottom of the ranking are many countries from Eastern and Southern Europe. Hungary comes last, preceded by Portugal. Who conducts the studies? When? Across which cultures? What is the procedure? What are the findings?
