National levels and educational inequalities in quit ratios in men in selected countries (source: Eurothine, 2007)

The Relative Index of Inequality (RII) can be interpreted as the ratio between the quit ratio in the highest educational group and the quit ratio in the lowest educational group. If the RII is larger than 1, this means that the quit ratio is higher in the highest educational group than in the lowest educational group.

The classification of the educational groups used in the figure above is adapted from the ISCED. Data apply to the 1990s and the early 2000s.
