Social Progress Index (SPI) is what measures

On my quest to find out if there are other means or mechanisms being developed to co-relate measures of economic abundance with real human satisfaction, I came across the Social Progress Imperative. The opening statement on the page - About the imperative - which explains the mission says it all:

Numerous studies have found a high correlation between economic growth and a wide variety of social indicators, yet there is growing awareness that economic measures alone do not fully capture social progress.

Their first initiative is the Social Progress Index (SPI), which aims at evaluating to what extent the governments have been successful in providing for the social and environmental needs of their citizens, and it takes into account 52 indicators across 3 major categories of Basic human needs, Foundations of well being and Opportunity.

There are 50 countries which have been evaluated and ranked in the first version, but more will follow.
US still seems to the land of opportunity..cliched..huh ;-)

Social Progress Network is another of their initiatives, and I do they can make a tangible difference by helping governments and policy makers understand where they stand and helping them formulate action plans for the future.
