2009-2013 MSOA Healthy Life Expectancy ( with analysis for comparison to total LE)
Definition Healthy Life Expectancy
A measure of the average number of years a person would expect to live in good health based on contemporary mortality rates and prevalence of self-reported good health. The prevalence of good health is derived from responses to a survey question on general health. For a particular area and time period, it is an estimate of the average number of years a newborn baby would live in good general health if he or she experienced the age-specific mortality rates and prevalence of good health for that area and time period throughout his or her life. Figures are calculated from deaths from all causes, mid-year population estimates, and self-reported general health status, based on data aggregated over a three year period. Figures reflect the prevalence of good health and mortality among those living in an area in each time period, rather than what will be experienced throughout life among those born in the area. The figures are not therefore the number of years a baby born in the area could actually expect to live in good general health, both because the health prevalence and mortality rates of the area are likely to change in the future and because many of those born in the area will live elsewhere for at least some part of their lives.
numerator
Number of deaths registered in the respective calendar years and the weighted prevalence of people reporting good or very good health from the Annual Population Survey.
denominator
ONS mid-year population estimates for the respective calendar years, Annual Population Survey sample weighted to local authority population totals.
