What are the Indices of Multiple Deprivation (IMD)

The Index of Multiple Deprivation (IMD) is the main statistical overview of relative deprivation covering the whole of England. It is formatted using small geographical areas called Lower Super Output Areas (LSOAs), of which there are 32844 across the country, with 422 of them falling within Northamptonshire. Each LSOA represents around 1,600 people. The IMD is released on an adhoc timescale by the Department for Communities & Local Government (DCLG). The 2015 release, analysed here, replaces the 2010 version and was created by Oxford Consultants for Social Inclusion (OCSI) on behalf of the DCLG.

The IMD is part of the English Indices of Deprivation. There are two other indices in the set :
The Income Deprivation Affecting Children Index (IDACI)
The Income Deprivation Affecting Older People Index (IDAOPI)

 

Indices of Multiple Deprivation - Technical Information

Indices of MultipleThe Index of Multiple Deprivation is constructed in hierarchical format using numerous national indicators to build up seven subject area ‘domains’ which then come together to create the overarching IMD using the weightings shown in the DCLG infographic below. At the end of this process each LSOA geography is given a ‘deprivation score’. To provide analysis of their relative levels of deprivation across the entire country, the LSOA geographies are then sorted according to their deprivation score, given a national ranking and then divided into ten equal sections (dectiles).

IMD Domains

To assess relative deprivation within Northamptonshire, the 422 county LSOAs are also given county ranks and county dectiles based on the deprivation score..

Nationally, the LSOA with Rank 1 is the most deprived and LSOA 32844 is the least deprived. Countywide, the LSOA with Rank 1 is the most deprived and LSOA 422 is the least deprived. Dectile 1 is the most deprived and Dectile 10 is the least deprived (nationally and countywide).

A key definition of deprivation used by local authorities is those areas (and their residents) which fall within the top 20% most deprived LSOAs nationally (ie. Dectiles 1 and 2 nationally).

Comparison between the IMD 2015 and the IMD 2010 should not be undertaken due to an increased number of LSOAs (implemented at the time of the last Census) and a slightly different methodology.

Most datasets used to build the indices relate to the 2012-13 financial year. 

Northamptonshire IMD Headlines

69 (16.4%) of Northamptonshire’s 422 LSOAs fall within the top 20% most deprived LSOAs in England.NorthantsIMD2015Map
The three most deprived LSOAs in the county are :
Northampton 011A Billing Aquadrome and Bellinge area
Northampton 021F Railway Station, St Peters Way and Industrial Estates area
Corby 006G Kingswood Oakley Road area
The least deprived is South Northamptonshire 009B North Brackley

 

Looking at the seven domains of the IMD, the following LSOAs are in the top 100 most deprived LSOAs in England for their particular domain :
Northampton 021F Railway Station, part of Town Centre, St Peters Way and Industrial Estates area (ranked 17th nationally in the Crime Domain)
Northampton 015C Racecourse area (ranked 39th nationally in the Crime Domain)
Northampton 011A Billing Aquadrome and Bellinge area (ranked 50th nationally in the Barriers to Housing Domain)
Corby 006D Kingswood (ranked 88th nationally in the Education, Skills & Training Domain).

It is also interesting to note that within Northamptonshire, the deprived population is made up of a higher proportion of children than the less deprived areas of the county. The population living in the top 20% most deprived LSOAs nationally is made up of 9.0% 0-4 year olds and 14.6% 5-15 year olds (compared to 6.2% and 13.2% respectively across the rest of the county).
