Life expectancy is a frequently used indicator of the overall health of a population: a longer life expectancy is generally a reflection of better health. Reducing the differences in life expectancy is a key part of reducing health inequalities.
Life expectancy at birth for an area is an estimate of how long, on average, babies born today may live if she or he experienced that area’s age-specific mortality rates for that time period throughout her or his life.
Healthy life expectancy, which estimates lifetime spent in ‘Very good’ or ‘Good’ health from birth is based upon self-perceived general health are calculated using self-reports of general health statuscollected in the Annual Population Survey (APS), and rely on a method developed by ONS to derive general health state prevalence for persons under 16 years of age.
