Inequality in healthy life expectancy at birth ENGLAND (female) (12003) Metric type
- Help text
- This sub-indicator measures inequalities in healthy life expectancy across England as a whole. Healthy life expectancy at birth is calculated for each national deprivation decile of lower super output areas and then the slope index of inequality (SII) is calculated based on these figures. The SII is a measure of the social gradient in healthy life expectancy, i.e. how much healthy life expectancy varies with deprivation. It takes account of health inequalities across the whole range of deprivation within England and summarises this in a single number. This represents the range in years of healthy life expectancy across the social gradient from most to least deprived, based on a statistical analysis of the relationship between healthy life expectancy and deprivation across all deprivation deciles.
Healthy life expectancy is 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.
In May 2017, three changes were made to the methodology for the calculation of the SII for data for 2010-12 onwards.1. A revised methodology for the calculation of life expectancy was implemented, to use an upper age band of 90 and over, whereas previously the upper age band was set to 85 and over. The change was made to reflect an increasing proportion of deaths at ages 85 and over, and results in greater accuracy of life expectancy estimates. This change was implemented by ONS for their sub-national life expectancy estimates in November 2016 2. IMD 2015 has been used to define deprivation deciles, replacing IMD 2010 which was previously used. Since IMD 2015 is constructed using data mostly from 2012/13, using it to group areas into deciles for the time periods that it most closely aligns with should produce a more accurate way of differentiating deprivation areas.3.Due to these changes, previously published data for 2002-04 onwards, are not comparable with the current data and have been removed.
