Sustainable Economic Development Assessment (SEDA)
SEDA is a comprehensive, objective diagnostic tool for evaluating the relative level of well-being for citizens in 148 countries plus Hong Kong, a special administrative region of China.
SEDA defines well-being through three elements—economics, investments, and sustainability—that comprise ten dimensions.
SEDA looks at countries' performance in well-being both as a snapshot—the current level—and in terms of change, or recent progress, during the period of 2006 to 2013.
