Counting importance: The case of life satisfaction and relative domain importance

The purpose of this study was to explore whether the use of relative domain importance as a weighting mechanism at the individual level improved the correlation between the global life satisfaction and domain satisfaction measures. Results from telephone interviews with adults 50 years old or above in Chicago suggest that compared to simple average of domain satisfactions, using discrete domain importance rating as a weighting factor did not improve the correlation between global life satisfaction measure and domain satisfactions. However, the correlation was improved by using domain ranking. The findings suggest that the weighted average of domain satisfactions using domain ranking is a better indicator of global life satisfaction than the simple sum or average of domain satisfactions.
