Figure 9. Within-Country Comparisons of Life Satisfaction and Household Income: Gallup World Poll
Source: Gallup World Poll, 2006.
Notes: Each circle aggregates satisfaction in one income category in one country, and its diameter is proportional to the population of that income category in that country. The vertical axis
plots the coefficients from an ordered probit regression of life satisfaction on indicator variables for each income category in each country, controlling for country fixed effects; the
horizontal axis plots the logarithm of average real household income in each country × income category, less the country average. The dashed line is from an OLS regression, weighting by
the number of respondents in each income category × country.
