require abandoning GDP as a measure for economic progress. Synergistic notions of prosperity Many distinct notions of prosperity, such as economic prosperity, health, and happiness, are correlated or even have causal effects on each other. Economic prosperity and health are well-established to have a positive correlation, but the extent to which health has a causal effect on economic prosperity is unclear. There is evidence that happiness is a cause of good health, both directly through influencing behavior and the immune system, and indirectly through social relationships, work, and other factors. One study which advances a holistic definition of prosperity is the Legatum Prosperity Index (an annual report by the Legatum Institute, a UK-based independent educational charity founded by Legatum), which uses data from 56 separate sources, including the World Health Organisation, Global slavery Index and World Bank, to rank 169 nations in an index which goes beyond GDP as a measurement of national prosperity. Ecological perspectives In ecology, prosperity can refer to the extent to which a species flourishes under certain circumstances.
