In weighted measures, inequality appears to be decreasing because populous countries like China and India are becoming richer. In unweighted measures, inequality is increasing in that income differences between individuals in poor and rich countries is growing. Different measures lead to different conclusions, and it is important to choose the appropriate measure for the comparison we want to make (for example, within or across countries). Causal effect 1.
