DolceTracker| The Gallup Organization has conducted the first worldwide survey of more than 136,000 people in 132 countries focused on happiness. More importantly, the Gallup survey attempts to differentiate between life satisfaction and the philosophical belief that you life is going well, and the day-to-day positive or negative feelings that one experiences in life.
Like previous studies, the new analysis found that life evaluation, or life satisfaction, rises with personal and national income. But positive feelings, which also increase somewhat as income rises, are much more strongly associated with other factors, such as feeling respected, having autonomy and social support, and working at a fulfilling job. via Science Daily
