The Boston Consulting Group's (BCG) 2018 Sustainable Economic Development Assessment (SEDA) ranked Lebanon in 96th place among 152 countries globally and in 11th place among 16 Arab countries in terms of well-being. It also ranked Lebanon in 33rd place among 40 upper middle-income countries (UMICs) included in the survey. Lebanon ranked in 99th place globally and in 11th place in the Arab world in the 2017 survey.

The SEDA measures a country's current level of overall well-being through 10 dimensions grouped into three fundamental elements that consist of Economics, Investments and Sustainability. The Economics element includes income, economic stability and employment; while the Investments element covers the quality of education, healthcare and infrastructure. Also, the Sustainability element covers the income equality, civil society, governance, and environmental dimensions. The survey assigns a score to each country from zero to 100, with 100 reflecting the highest level of well-being. 

Globally, Lebanon has a higher level of well-being than Bolivia, the Philippines and Botswana, and a lower level than Paraguay, Morocco and Algeria among economies with a GDP of $10bn or more. Also, Lebanon's level of well-being was higher than that of Egypt, Iraq, Yemen, Mauritania and Sudan among Arab countries. Lebanon received a score of 44.8 points, lower than the global median score of 48.5 points, the UMICs' median of 50.5 points and the Arab region's median score of 47.25 points. Also, Lebanon's score was lower than the Gulf Cooperation Council (GCC) countries' median of 64.8 points, while it was higher than the median score of 44 points for non-GCC Arab countries. In parallel, Lebanon's score fell by 1.5 points between the 2009 and 2018 surveys, which shows a decline in the country's well-being. Globally, Ukraine, Cyprus, the Bahamas, Greece, Venezuela and Yemen were the only countries to post a steeper deterioration than Lebanon in their well-being.

Further, the BCG provided the wealth-to-well-being coefficient, which compares a country's SEDA score of well-being with the potential score of well-being in relation to the country's gross national income (GNI) per capita. As such, the coefficient provides an indicator of how well a country has converted its wealth into well-being for its population. Lebanon's coefficient came at 0.92 points, which means that Lebanon has delivered a lower level of well-being than what would be expected given its GNI per capita level. Countries with a coefficient of one are generating well-being to their population in line with what would be expected given their income levels. Countries with a coefficient greater than one deliver higher levels of well-being to their society than would be expected given their GNI, while counties with a coefficient below one deliver a level of well-being to the population lower than would be expected given their wealth levels. Lebanon's coefficient is the 41st lowest globally, the sixth lowest among UMICs and the eighth lowest among Arab countries. Globally, Lebanon's coefficient of conversion of wealth is similar to that of Bangladesh, Italy, Kenya, Qatar and the United Kingdom.
