This is the eighth World Happiness Report. We use this Foreword, the first we have had, to offer our thanks to all those who have made the Report possible over the past eight years, and to announce our expanding team of editors and partners as we prepare for our 9th and 10th reports in 2021 and 2022. The first seven reports were produced by the founding trio of co-editors assembled in Thimphu in July 2011 pursuant to the Bhutanese Resolution passed by the General Assembly in June 2011, that invited national governments to “give more importance to happiness and well-being in determining how to achieve and measure social and economic development.” The Thimphu meeting, chaired by Prime Minister Jigme Y. Thinley and Jeffrey D. Sachs, was called to plan for a United Nations High-Level Meeting on ‘Well-Being and Happiness: Defining a New Economic Paradigm’ held at the UN on April 2, 2012. The first World Happiness Report was prepared in support of that meeting, bringing together the available global data on national happiness and reviewing evidence from the emerging science of happiness.

Although the World Happiness Reports have been based on a wide variety of data, the most important source has always been the Gallup World Poll, which is unique in the range and comparability of its global series of annual surveys. The life evaluations from the Gallup World Poll provide the basis for the annual happiness rankings that have always spurred widespread interest. Readers may be drawn in by wanting to know how their nation is faring, but soon become curious about the secrets of life in the happiest countries.
