The relationship between inequality and subjective well-being (e.g. life satisfaction) has received
sustained research attention in recent years – in part, perhaps, because a consensus has proved
elusive. Most investigations in this area are cross-sectional: researchers generally perceive a
constraint to longitudinal analysis, rooted in the view that it is necessary to include controls for
individual-level determinants of SWB. I argue here that individual-level controls are not needed
for this question – and we can then construct a longitudinal analysis by taking country-level
averages of life satisfaction from repeated cross-sectional data and regressing them (using a
‘within’ specification) on repeated Gini measures. We then see, in contrast to some influential
previous findings, that inequality does not have any substantial positive impact on life
satisfaction. In wealthy countries increased inequality has a substantial negative impact on life
satisfaction, while in poorer countries any effect (positive or negative) is small. The longitudinal
analysis presented here is less prone to bias from omission of confounders; there is then reason to
believe that the findings presented in previous (cross-sectional) research are biased upwards via
failure to control for unobserved confounders.
