Health inequalities can be described in different ways. Two indicators are presented in this section, and they both relate to mortality (rather than morbidity). The first is a measure of the dispersion in the ages of death ‐ or, alternatively,
in the length of life ‐ among individuals in different OECD country, as defined by Edwards and Tuljapurkar (2005). The specific measure of dispersion in the age of death used is the standard deviation of all deaths above the age of 10. The main advantages
of this indicator are its simplicity and the fact that it provides a direct measure of health inequality between individuals. This indicator is based on data from the Human Mortality Database, and is available as a time series for most OECD and non‐OECD countries,
for both the total population and by gender.
