Summarised presentation of estimated trends in absolute and relative inequality in all-cause mortality
Notes for figure:
The left hand chart shows absolute mortality inequality (SRD for ethnic and SII for income inequality). SRD is the age standardised mortality rate difference. SII (slope index of inequality) is the regression-based equivalent of the SRD, standardised for both age and ethnicity.
The right hand chart shows relative mortality inequality (SRR for ethnic and RII for income inequality). SRR is the age standardised mortality rate ratio. RII (relative index of inequality) is the regression-based equivalent of the SRR, standardised for both age and ethnicity.
[SII and RII are better measures of inequality than SRD and SRR respectively, as they take into account changes in the sizes of the groups. However, these measures can be used only for groups that are ranked (eg income groups)].
