To the long list of maps - topographical, political, demographic - you can add one more: attitudinal. Researchers at the University of Leicester in the United Kingdom recently published the first world map of happiness. Using data from the emerging science of happiness, they created a color-coded atlas of bliss, a topography of the human spirit, from Algeria to Zimbabwe.
After ignoring the subject for a century or so, psychologists and other academics are going gaga over happiness, or subjective well being, to use the preferred term. They're churning out hundreds of papers on the subject each year. There are conferences, a Journal of Happiness Studies, and a World Database of Happiness. So why not a map?
