Figure 14. Subjective Well-Being-Income Gradients across Time: World Values Survey
Source: World Values Survey, waves 1-4. Sources for GDP per capita are described in the text.
Notes: Arrows show the evolution of measured well-being and real GDP for each country. Dotted arrows join observations based on noncomparable sampling frames (see appendix B).
Dashed line is fitted from an OLS regression of the well-being measure on the natural log of real GDP, estimated from pooling all four waves. See notes to figure 3 for question details and
construction of aggregate well-being indices. Real GDP is at purchasing power parity in constant 2000 international dollars.
