The index measures social progress directly, independent of economic development. It is based on a holistic and rigorous framework for defining social progress based on 54 indicators of social and environmental outcomes.
The top three countries in the world in terms of social progress are New Zealand, Switzerland, and Iceland.
The remainder of the top ten includes a group of Northern European nations (Netherlands, Norway, Sweden, Finland, and Denmark), Canada, and Australia. Together with the top three, these countries round out a distinct “top tier” of countries in terms of social progress scores.
A notch lower is a second tier of countries that includes a group of 13 countries, ranging from Austria to the Czech Republic. This group includes a number of the world’s leading economies in terms of GDP and population, including five members of the G-7: Germany, the United Kingdom, Japan, the United States, and France.
The next level of social progress is a third tier of countries, ranging from Slovakia to Israel. This diverse group of nations includes countries at sharply different levels of economic development, ranging from Costa Rica (which significantly out-performs its rank in terms of GDP) to the United Arab Emirates (which has one of the highest measured GDPs per capita in the world but is ranked 37th in terms of SPI). Clearly high GDP per capita alone does not guarantee social progress.
At the next, fourth, tier is a large group of approximately 50 countries ranging from Kuwait at 40th to Morocco at 91st. These countries are closely bunched in terms of their overall Social Progress Index score, but have widely differing strengths and weaknesses.
A fifth tier of countries which includes Iran have substantially lower social progress scores than the fourth. Many of these countries also have low GDP per capita, but some are much more highly ranked on GDP per capita.
