This self-reporting template is designed to provide estimates of healthy life expectancy in five-year age bands for a given population using the Sullivan method of health expectancy calculation. In the calculation of estimates of healthy life expectancy for males or females in the UK, the Office for National Statistics uses mid-year population estimates and period life tables aggregated over three years along with survey data from the Annual Population Survey. Disability-free life expectancy is calculated using exactly the same methodology and this spreadsheet can easily be adapted for this measure by replacing “not good” health with limiting chronic illness and “good” or “fairly good” health with “no limiting chronic illness”. Data required for healthy life expectancy calculations are indicated by red text (the lighter coloured text) in the column headings and described in the column description row below.
