註釋Widely used summary statistical indicators of inequality or the disappearing middle class are potentially misleading. Four kinds of divergence between evidence cited and conclusions claimed are considered. The first is a distinction between the fundamental concepts of inequality and polarization. Second, some measures in wide use do not correspond to the gold standard concept of inequality rankings based on Lorenz curves. Beyond these conceptual problems, claims made about trends in inequality may be inappropriate because they fail to account for sampling variability, or because they should be more clearly circumscribed when only a sub-population like full-time male workers is being considered. For all of these cases of potential divergence, examples are given using Canadian data on labour incomes over the 1967 to 1991 period.
