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.
Data now available for 2006-10. All data revised using IMD 2010.
The Public Health Outcomes Framework consultation, published on 20 December 2010, proposed the slope index of inequality
in life expectancy within every local authority as one of the public health outcomes indicators for assessing health inequalities.
Guide to interpretation of the indicator
Guide to assist with interpretation of the slope index of inequality in life expectancy. Includes questions and answers, and technical information on the data sources and calculation methods.
Slope index of inequality data
All the data presented on this page have been updated using IMD 2010 as the basis for assigning super-output areas (LSOAs) to deprivation categories. Hence they are not comparable with the slope index data published previously by APHO for local authorities and primary care organisations.
Instant Atlas tools showing maps and graphs of the slope index of inequalities for life expectancy data published on this page. Data for IMD 2010 and overall life expectancy for 2006-10 are also included.
Life expectancy data for local authority deprivation deciles
Summary charts for each local authority
Summaries for each local authority (unitary authorities, counties and county districts), showing charts of the slope index of inequality for males and females and a table of the data for 2006-10.
Summary charts for each primary care organisation
Summaries for each primary care organisation, showing charts of the slope index of inequality for males and females and a table of the data for 2006-10.
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.
LSOA-LA deprivation decile lookup table
Lookup table used in the calculation of the SIIs on this page to allocate LSOAs to IMD 2010 deprivation deciles in each local authority (unitary authorities, counties and county districts) and primary care organisation.
Lookup tables allocating LSOAs to deciles, quintiles and quartiles in each English region, strategic health authority and across England as a whole are available here, along with summary IMD scores for wards, MSOAs, local authorities, PCOs and the English regions.
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.
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.
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.
