The relative wealth disparity metric is instead intended to shed light on the inequalities in the conditions facing the richest and poorest in urban and rural areas of the same country. In contrast, in rural areas the gap of approximately 41 percentage points for low-income countries only halves to approximately 22 percentage points for upper-middle income countries. However, it is also partly explained by the observed greater wealth of urban households. Among a separate sample of 88 countries, on average, 83 per cent of the richest quintile lives in urban areas, with just 17 per cent in rural areas (unweighted averages).
