Summary measures are measures that combine both mortality and morbidity data.
This section includes two classes of comprehensive indices that quantify the level of health at population level:
- life expectancy: the average number of years a person may expect to live, based on age-specific mortality data; and
- healthy life expectancy: the number of years a person may expect to live in good health, based on a group of measures.
Healthy life expectancies are calculated by subtracting the years in lesser health from a person's life expectancy, and thus combine information on mortality and ill-health. Different types of healthy life expectancies use different basic data and principles to calculate the years in lesser health.
