abstract: 'In recent work, the concentration index has been widely used as a
|
|
|
|
|
|
|
|
|
|
measure of income-related health inequality. The purpose of this note is
|
|
|
|
|
|
|
|
|
|
to illustrate two different methods for decomposing the overall health
|
|
|
|
|
|
|
|
|
|
concentration index using data collected from a Short Form (SF-36)
|
|
|
|
|
|
|
|
|
|
survey of the general Australian population conducted in 1995. For
|
|
|
|
|
|
|
|
|
|
simplicity, we focus on the physical functioning scale of the SF-36.
|
|
|
|
|
|
|
|
|
|
Firstly we examine decomposition `by component'' by separating the
|
|
|
|
|
|
|
|
|
|
concentration index for the physical functioning scale into the ten
|
|
|
|
|
|
|
|
|
|
items on which it is based. The results show that the items contribute
|
|
|
|
|
|
|
|
|
|
differently to the overall inequality measure, i.e. two of the items
|
|
|
|
|
|
|
|
|
|
contributed 13\% and 5\%, respectively, to the overall measure. Second,
|
|
|
|
|
|
|
|
|
|
to illustrate the `by subgroup'' method we decompose the concentration
|
|
|
|
|
|
|
|
|
|
index by employment status. This involves separating the population into
|
|
|
|
|
|
|
|
|
|
two groups: individuals currently in employment; and individuals not
|
|
|
|
|
|
|
|
|
|
currently employed. We find that the inequality between these groups is
|
|
|
|
|
|
|
|
|
|
about five times greater than the inequality within each group. These
|
|
|
|
|
|
|
|
|
|
methods provide insights into the nature of inequality that can be used
|
|
|
|
|
|
|
|
|
|
to inform policy design to reduce income related health inequalities.
