Using the data reported in Table 5 (column 2), averaging across years, and extrapolating trends for countries where available data cover only a short period, it can be shown that the Gini coefficient for market income has, on average, increased by 16% over a ten-year period across the countries shown. This is a very substantial increase over a relatively short period of time. For instance, and as discussed below, 16% is the same order of magnitude as the reduction in inequality among the non-elderly population that is achieved by the entire tax-benefit system in some countries (e.g., Switzerland or the United States).
