Health inequality indicators for local authorities and primary care organisations

The Network of Public Health Observatories is now part of Public Health England.

This page contains historical information.

This page gives access to data on health inequality in each local authority and primary care organisation in England. The statistic presented is the slope index of inequality in life expectancy, for males and for females. Summaries are provided for each area.

The Slope Index and decile data presented here have been superseded: data for 2002-2012 are now available in the Public Health Outcomes Framework Tool.

Inequalities Calculation Tool

The Excel tool linked to below can be used to calculate a range of different inequality measures, including the Slope Index of Inequality, Concentration Index and Gini Coefficient.

Marmot indicators

The data are also presented, along with other indicators (including slope index values for disability-free life expectancy) in the Marmot Indicators for Local Authorities in England on the LHO website. Note that the Marmot Indicators were calculated using IMD 2007 so will differ slightly from the resources on this page, which were produced using IMD 2010.

Adjusted IMD2010 scores for 2011 LSOAs

Adjustments have been made to the published IMD2010 scores in areas affected by changes to LSOA boundaries in 2011 to enable their continued use with the latest LSOA boundaries.

Two sets of scores are provided: for the overall Index of Multiple Deprivation (IMD) and for the Income Domain. Each file contains a set of adjusted scores, with details of how the adjustments were made.

The adjusted scores have also been used to assign 2011 LSOAs to deprivation quintiles/deciles within England as a whole and also within English regions, counties, and local authorities.


This method of calculating inequality in life expectancy was originally developed by the Association of Public Health Observatories (APHO) for the Department of Health.

The original paper from APHO making recommendations to the Department of Health on the Health Inequality Indicator is available here. The paper explains the background and justification for the indicator.
