• Resumen

  • This paper aims to extend the existing linear decomposition techniques for the concentration index to generalised linear models. The second order Taylor expansion is used to derive a linear approximation of the partial concentration indices. This approach adheres closely to the standard decomposition method in the linear settings. The method is illustrated using age-sex standardised mortality rate data from Australia to examine the socioeconomic determinants of Indigenous health inequality. The empirical results demonstrate the usefulness of this method. The new approach provides a more efficient and flexible way to quantify the contributions of the underlying determinants of health inequality in a nonlinear and multivariate context.
