CPRD Aurum linked small area level socio-demographic and socio-economic data mapped to the postcode of the patient, including the Index of Multiple Deprivation, Carstairs Index and Townsend Deprivation Index.

This dataset provides detailed information on the 2019 Index of Multiple Deprivation (IMD) for Birmingham, UK. The data is available at the postcode level and includes the Lower Layer Super Output Area (LSOA) information.Data is provided at the LSOA 2011 Census geography.The decile score ranges from 1-10 with decile 1 representing the most deprived 10% of areas while decile 10 representing the least deprived 10% of areas.The IMD rank and decile score is allocated to the LSOA and all postcodes within it at the time of creation (2019).Note that some postcodes cross over LSOA boundaries. The Office for National Statistics sets boundaries for LSOAs and allocates every postcode to one LSOA only: this is the one which contains the majority of residents in that postcode area (as at 2011 Census).

The Index of Multiple Deprivation (IMD) is a measure used in the UK to assess the relative deprivation of small areas, known as Lower-layer Super Output Areas (LSOAs). It combines information from seven different domains to provide an overall deprivation score for each area. These domains are:

Income Deprivation Employment Deprivation Education, Skills, and Training Deprivation Health Deprivation and Disability Crime Barriers to Housing and Services Living Environment Deprivation

Each domain is weighted and combined to create a single deprivation score, which is then used to rank all LSOAs in England from the most deprived to the least deprived.

The IMD is widely used by government and organizations to allocate resources, target interventions, and develop policies aimed at reducing deprivation and improving quality of life in the most deprived areas.

The Canadian Index of Multiple Deprivation (CIMD) is an area-based index which used 2016 Census of Population microdata to measure four key dimensions of deprivation at the dissemination area (DA)-level: residential instability, economic dependency, situational vulnerability and ethno-cultural composition. Using factor analysis, DA-level factor scores were calculated for each dimension. Within a dimension, ordered scores were assigned a quintile value, 1 through 5, where 1 represents the least deprived and 5 represents the most deprived. The CIMD allows for an understanding of inequalities in various measures of health and social well-being. While it is a geographically-based index of deprivation and marginalization, it can also be used as a proxy for an individual. The CIMD has the potential to be widely used by researchers on a variety of topics related to socio-economic research. Other uses for the index may include: policy planning and evaluation, or resource allocation.

CPRD GOLD linked small area level socio-demographic and socio-economic data mapped to the postcode of the patient, including the Index of Multiple Deprivation, Carstairs Index and Townsend Deprivation Index.

Patient postcode linked measures are available for patients in English practices that have consented to participate in the linkage scheme. Data are linked via Lower Super Output Area (LSOA), Super Output Area (SOA) in Northern Ireland and datazone (DZ) in Scotland. The latest available patient postcode of residence is mapped to an LSOA boundary. The LSOA of residence then allows linkage to the following LSOA-level deprivation measures: 2004 English Index of Multiple Deprivation; 2007 English Index of Multiple Deprivation; 2010 English Index of Multiple Deprivation; 2015 English Index of Multiple Deprivation (composite and individual domains); Townsend Deprivation Index: calculated using unadjusted 2001 census data; Carstairs Index using 2011 census data.

Data are provided as quintiles, deciles or twentiles of the deprivation score to prevent disclosure of patient location. In order to prevent the possibility of deductive disclosure of a patients’ area of residence, researchers will only be provided with one of the above linked datasets for any one study.

Please note that Deprivation Ranks are released at Lower Super Output Area/Data Zone level and are not for each individual postcode.

Suppressed postcodes in Northern Ireland

For confidentiality reasons, counts were suppressed for postcodes that had less than 10 usual residents and had only 1, 2 or 3 households in them.

The Registrar General took steps to ensure that the confidentiality of respondents was fully protected. Accordingly, all published results from the 2011 Census (including those relating to Postcodes) were subject to statistical processes to ensure that individuals could not be identified. For these postcodes, averages were taken at Postcode District level and released in a separate table, which can be found below.

Missing postcodes

These postcodes are based upon the sets of enumeration postcodes provided by the three UK census agencies. Enumeration postcodes are a subset of the complete set of live postcodes at the time of the 2011 Census. These are aggregated to create census output areas, which are themselves aggregated to create most other census geographies.

Only postcodes with at least one resident person are included. Many postcodes, such as those assigned to businesses, don't have any resident populations and so won't appear in the table.

Postcodes are quite volatile; new postcodes are created and old ones are terminated regularly. Existing/live postcodes can also change through the addition or removal of delivery points. The ONSPD records all live and terminated postcodes. Each postcode has a date of introduction and, if relevant, a date of termination. Things are complicated further because postcodes can be re-used, so a postcode can be terminated and then reappear with a new date of introduction, replacing/removing the record for the previous instance of the postcode. Postcodes that weren't current at the time of the census also won't appear in the table.

The Townsend Deprivation Index is a measure of material deprivation first introduced by Peter Townsend in 1987. A Townsend score can be calculated using a combination of four census variables for any geographical area (provided census data is available for that area). The measure has been widely used in research for health, education and crime to establish whether relationships exist with deprivation. The Townsend scores below were calculated for the UK based on data from the 2011 Census and include a discussion with geographical visualisations of the findings.

The National Material and Social Deprivation Indices (MSDI) for all Canadian Census enumeration areas (now called dissemination areas) were downloaded July 21, 2017 by CANUE staff from the INSPQ website. The indices were provided in Excel spreadsheets named TableEquivalenceCompleteCanada1991.xlxs; TableEquivalenceCompleteCanada1996.xlxs; TableEquivalenceCompleteCanada2001.xlxs; TableEquivalenceCompleteCanada2006.xlxs; andTableEquivalenceCompleteCanada2011.xlxs. Data for 2016 were provided directly to CANUE by INSPQ.ArcGIS was used by CANUE staff to associate the single link DMTI Spatial postal codes to the Statistics Canada enumeration/dissemination area boundary file, and then spatially join the MSDI data to DMTI single link postal codes using enumeration or dissemination area as a unique identifier. There may be many postal codes within a single enumeration or dissemination area - these will have the same index values. CANUE staff translated the variable names from French to English and added a distance attribute (maximum distance from postal code centroid to boundary of census area).

Abstract

ADI: An index of socioeconomic status for communities. Dataset ingested directly from BigQuery.

Documentation

The Area Deprivation Index (ADI) can show where areas of deprivation and affluence exist within a community. The ADI is calculated with 17 indicators from the American Community Survey (ACS) having been well-studied in the peer-reviewed literature since 2003, and used for 20 years by the Health Resources and Services Administration (HRSA). High levels of deprivation have been linked to health outcomes such as 30-day hospital readmission rates, cardiovascular disease deaths, cervical cancer incidence, cancer deaths, and all-cause mortality. The 17 indicators from the ADI encompass income, education, employment, and housing conditions at the Census Block Group level.

The ADI is available on BigQuery for release years 2018-2020 and is reported as a percentile that is 0-100% with 50% indicating a "middle of the nation" percentile. Data is provided at the county, ZIP, and Census Block Group levels. Neighborhood and racial disparities occur when some neighborhoods have high ADI scores and others have low scores. A low ADI score indicates affluence or prosperity. A high ADI score is indicative of high levels of deprivation. Raw ADI scores and additional statistics and dataviz can be seen in this ADI story with a BroadStreet free account.

These indicators are designed to accompany the SHMI publication. The SHMI methodology does not make any adjustment for deprivation. This is because adjusting for deprivation might create the impression that a higher death rate for those who are more deprived is acceptable. Patient records are assigned to 1 of 5 deprivation groups (called quintiles) using the Index of Multiple Deprivation (IMD). The deprivation quintile cannot be calculated for some records e.g. because the patient's postcode is unknown or they are not resident in England. Contextual indicators on the percentage of provider spells and deaths reported in the SHMI belonging to each deprivation quintile are produced to support the interpretation of the SHMI. Notes: 1. For discharges in the reporting period April 2024 - May 2024, almost all of the records for Wirral University Teaching Hospital NHS Foundation Trust (trust code RBL) have been submitted without an NHS number. This will have affected the linkage of the HES data to the ONS death registrations data and may have resulted in a smaller number of deaths occurring outside hospital within 30 days of discharge being identified for this trust than would have otherwise been the case. The results for this trust should therefore be interpreted with caution. 2. Northern Lincolnshire and Goole NHS Foundation Trust (trust code RJL) has a high percentage of records with no NHS Number. This is resulting in around 40% of their spells not having a value for Age or Deprivation rank. As Age is a component of the statistical models used to calculate the SHMI, values for this trust should therefore be interpreted with caution. 3. There is a shortfall in the number of records for North Middlesex University Hospital NHS Trust (trust code RAP), Northumbria Healthcare NHS Foundation Trust (trust code RTF), The Rotherham NHS Foundation Trust (trust code RFR), and The Shrewsbury and Telford Hospital NHS Trust (trust code RXW). Values for these trusts are based on incomplete data and should therefore be interpreted with caution. 4. A number of trusts are now submitting Same Day Emergency Care (SDEC) data to the Emergency Care Data Set (ECDS) rather than the Admitted Patient Care (APC) dataset. The SHMI is calculated using APC data. Removal of SDEC activity from the APC data may impact a trust’s SHMI value and may increase it. More information about this is available in the Background Quality Report. 5. Further information on data quality can be found in the SHMI background quality report, which can be downloaded from the 'Resources' section of this page.

The general practice postcode linkages are available for all practices in CPRD GOLD and CPRD Aurum and use the general practice postcode which is linked via LSOA, SOA in Northern Ireland and datazone (DZ) in Scotland. The general practice postcode linkage includes several well-known area-based measures of deprivation, including the Index of Multiple Deprivation, Townsend Deprivation Index and Carstairs Index, and Rural-Urban Classification, which are available at the LSOA level for linkage to CPRD primary care data through the practice postcode. Additionally, Sub-Integrated Care Board Locations (Sub-ICB Locs) pseudonym (practice level, England-only) is available. Access is provided by CPRD subject to protocol approval.

The Index of multiple deprivation (IMD) combines information from the English Indices of deprivation (IoD). It is the Government's official measure of relative deprivation for LSOAs (Lower layer super output areas). LSOAs are small geographical areas of approximately 1,700 people. There are 128 LSOAs in Calderdale. The IoD is a set of relative measures of deprivation for LSOAs across England, based on seven different domains of deprivation: Income, Employment, Education skills and training, Health and disability, Crime, Barriers to housing and services, and Living environment. There are also seven domain level indices and two supplementary indices - Income deprivation affecting children index (IDACI) and Income deprivation affecting older people index (IDAOPI). It is published every three to five years. IMD 2019 results were published on 26 September 2019. Calderdale results are available, using the dashboard link on this page. More information is available at Ministry of Housing, Communities and Local government: English Indices of deprivation 2019.

The Index of Multiple Deprivation (IMD) is one of a set of English indices of deprivation, and are released by the Department for Communities and Local Government every three to five years. The latest statistics are for 2015, and use data from 2012 to 2013. IMD results are sometimes used as criteria for external funding bids (eg Big Lottery).

IMD 2015 is the Government’s official measure of relative deprivation for LSOAs. LSOAs are small geographic areas of approximately 1,500 people, and there are 128 LSOAs in Calderdale.

The data is provided at Lower layer Super Output Area (LSOA), Neighbourhood and Ward levels in Calderdale. It shows rank, decile and percentage compared with 38,824 LSOAs in England.

IMD 2015 was published in September 2015 and replaces previous IMD publications. More information is available from Department for Communities and Local Government (DCLG) English indices of deprivation 2015 .
