"... These are among the findings of the first ever World Happiness Report (download PDF), commissioned for the April 2nd United Nations Conference on Happiness (mandated by the UN General Assembly). The report, published by the Earth Institute and co-edited by the institute’s director, Jeffrey Sachs, reflects a new worldwide demand for more attention to happiness and absence of misery as criteria for government policy. It reviews the state of happiness in the world today and shows how the new science of happiness explains personal and national variations in happiness."
