Chart Summary

The chart from Gallup shows the relationship between GDP per Capita and Life Satisfaction (i.e. happiness). As can be seen there is a strong correlation between GDP per capita and happiness of a population. Please note that the X-axis uses a logarithmic scales so the impact of GDP per Capita on happiness is even more dramatic than chart conveys.

Key Lesson

If your goal is to improve life satisfaction of a society, increasing GDP per Capita must be a key component of your plan.
