The second indicator in Annex Table 10 is based on the overall attainment measure
presented in Annex Table 9 and assesses performance relative to the frontier defined for all
five elements of achievement. The intervals around these values are much larger than for
DALE alone because of the uncertainty surrounding the other components. These components
also account for some considerable changes in the ranking, but the best performing
systems still seem to be those of relatively rich countries and the worst off are predominantly
poor and in Africa. Figure 2.7 presents the distribution of overall performance, which
shows somewhat less variation than Figure 2.6: countries that perform poorly with respect
to health alone sometimes compensate for this by doing better in responsiveness or financing
or in dealing with health inequality. Nonetheless the rankings of the two performance
measures are rather closely associated, with a small number of countries that do much
better by one measure than by the other.
