The Segment Tool has been developed by Public Health England's Epidemiology and Surveillance team and provides information on life expectancy and the causes of death that are driving inequalities in life expectancy at national, regional and local area levels. Targeting the causes of death which contribute most to the life expectancy gap should have the biggest impact on reducing inequalities.

The tool allows users to view the breakdown of the life expectancy gap both within areas, and between a local authority and England as a whole.

The tool is provided in an easy to use Excel workbook, which can be downloaded below. The tool uses macros, and you should make sure that these are enabled before starting to use the tool. A summary report for each local authority showing the charts and tables can be downloaded using the dropdown boxes at the top of this page. Summary reports for England as a whole, and for each English Region, can be downloaded from the links at the bottom of this page.

The presentation of the tool is the same as the previous version, but because of changes to the data sources and methodology, the results here are not directly comparable. However, the older version is still available to view here:

If you need help with using the tool or have any questions, a user guide provides information on how to use the tool, interpret the charts and tables and answers to a set of frequently asked questions. A technical document provides more detailed information on the data sources and methodology used to create the charts.

Recent updates

May 2016

The tool was updated in May 2016. Several changes have been made to the tool since the previous version in January 2015. These are:

  • Update of data to 2012-14
  • Update to use the new Index of Multiple Deprivation 2015 to define the most and least deprived areas
  • Adjustment of counts of deaths to take account of changes in ICD-10 coding made in 2014

Because of these changes, the results in this version of the tool should not be compared to the previous version.
