Life expectancy at birth is a key summary measure of mortality and morbidity in a population and one of the overarching indicators in the Department of Health’s Public Health Outcomes Framework. It represents the average number of years that a baby born in a particular area can expect to live should he/she experience the current age-specific mortality rates of that area throughout their life. Average life expectancy at birth represents the cumulative effect of the prevalence of risk factors, prevalence and severity of disease, and the effectiveness of interventions and treatment across the life course.
Inequalities in Life Expectancy
Public Health England’s Segment Tool provides information on life expectancy and causes of death that drive inequalities at local level. Targeting the causes of death which contribute most to life expectancy gaps should have the biggest impact on reducing inequalities. A Segment Tool report for Cambridgeshire and Peterborough provides an overview of the data in the tool at upper-tier and lower-tier local authority level and by deprivation quintile, highlighting the main causes of death contributing to inequalities in our area.
