Gross National Happiness (GNH), sometimes called Gross Domestic Happiness (GDH), is a philosophy that guides the government of Bhutan. It includes an index which is used to measure the collective happiness and well-being of a population. Gross National Happiness Index is instituted as the goal of the government of Bhutan in the Constitution of Bhutan, enacted on 18 July 2008. History The advent and concept of "Gross National Happiness" (GNH) germinated in the mind of Bodhisattva Druk Gyelpo, the 4th King of Bhutan, Jigme Singye Wangchuk, groomed with the evolution of "Gaki Phuensum" (Peace and Prosperity) and the modernization period of Bhutan during the reign of Druk Gyelpo, the 3rd King of Bhutan, Jigme Dorji Wangchuk. The term "Gross National Happiness" as conceptualized by the 4th King of Bhutan, Jigme Singye Wangchuck, in 1972 was declared as, "more important than Gross Domestic Product." The concept implies that sustainable development should take a holistic approach towards notions of progress and give equal importance to non-economic aspects of wellbeing. In 2011, The UN General Assembly passed resolution 65/309, "Happiness: towards a holistic approach to development", urging member nations to follow the example of Bhutan and measure happiness and well-being and calling happiness a "fundamental human goal." In 2012, Bhutan's Prime Minister Jigme Thinley and the Secretary-General Ban Ki-Moon of the United Nations convened the High Level Meeting: Well-being and Happiness: Defining a New Economic Paradigm to encourage the spread of Bhutan's GNH philosophy. At the meeting, the first World Happiness Report was issued. Shortly afterward, 20 March was declared to be International Day of Happiness by the UN in 2012 with resolution 66/28. Bhutan's Prime Minister Tshering Tobgay proclaimed a preference for focusing on more concrete goals instead of promoting GNH when he took office, but subsequently has protected the GNH of his country and promoted the concept internationally. Other Bhutanese officials also promote the spread of GNH at the UN and internationally. Definition GNH is distinguishable from Gross Domestic Product by valuing collective happiness as the goal of governance, by emphasizing harmony with nature and traditional values as expressed in the 9 domains of happiness and 4 pillars of GNH. According to the Bhutanese government, the four pillars of GNH are: sustainable and equitable socio-economic development; environmental conservation; preservation and promotion of culture; and good governance. The nine domains of GNH are psychological well-being, health, time use, education, cultural diversity and
