2010 English Indices of
Multiple Deprivation
** Revised 11th April 2011 **
Local authority level summary report
Summary
 The IMD 2010 is based where possible on data from 2008.
 This report used revised data published by Communities and Local Government, which
has summarised the IMD 2007 for the post 2009 local government review authorities.
The release of this data allows direct comparison with the 2010 IMD local authority
summaries.
 Blackburn with Darwen ranks as the 17th most deprived authority in England on the ‘rank
of average score’ summary. (There are five other summary scores available). On the
comparable 2007 IMD, the borough ranked 16th.
 Blackburn with Darwen remains the fourth most deprived local authority on the rank of
average score, of the AGMA and Lancashire district authorities and the sixth most
deprived in the North West.
Background
The Index of Multiple Deprivation 2010 provides indicators of deprivation at local authority and
lower super output area level (LSOA). (Lower super output areas are a statistical geography and
are smaller in size than wards. They are a statistical cluster of around 1,500 people).
The IMD 2010 replicates the methodology and where possible, the indicators used in both the
IMD 2007 and 2004, allowing a level of comparability.
However, it must be noted that between the release of the IMD 2010 and 2007 there was a
local authority re-structure in a number of areas in England. The IMD 2010 and the comparable
IMD 2007 are ranked out of 326 local authorities. The borough ranked 1st is the most
deprived.
Domains
The seven domains and weightings used in all three indices are:
Income deprivation (domain weight 22.5%)
Employment deprivation (domain weight 22.5%)
Health deprivation and disability (domain weight 13.5%)
Education skills and training deprivation (domain weight 13.5%)
Barriers to housing and services (domain weight 9.3%)
Living environment deprivation (domain weight 9.3%)
Crime (domain weight 9.3%)
Supplementary indices have also been produced, these include:
Income Deprivation Affecting Children
Income Deprivation Affecting Older People
Where possible, the indicators used in the IMD 2010 relate to the year 2008, a small number
of indicators remain sourced from the 2001 Census. For further information on the indicators
used to calculate the IMD 2010 please see:
http://www.communities.gov.uk/publications/corporate/statistics/indices2010
Local authority summaries
The IMD is summarised for each local authority in six different ways. These summaries show
different aspects of deprivation. No single summary measure is favoured over another and
there is no single best way of describing or comparing England’s 326 local authority districts.
Average scores and average ranks:
Both these measures are ways of depicting the average level of deprivation across the entire
local authority.
Local concentration:
This shows the severity of deprivation in each authority, measuring ‘hot spots’ of deprivation.
Extent:
This measures the proportion of a district’s population that lives in the most deprived LSOAs in
England.
Income scale:
This measures the number of people experiencing income deprivation.
Employment scale:
This measures the number of people experiencing employment deprivation.
Comparing indices of deprivation
As the domains and methodology used in all three indices have remained the same where
possible, the data can be used to examine change between the two time periods.
It is important to remain aware that the IMD measures relative deprivation, not absolute
deprivation. Where there have been any changes in ranks, this is a change in the relative
position of an area compared to another area, not whether an area has more or less actual
deprivation. For example, if all areas improve at relatively the same rate, the rankings will stay
the same.
Although the domains and overall methodology has remained the same as 2007, some minor
changes in the indicators used to calculate the index have had to be made. Further information
on these changes can be found in the IMD 2010 Technical report. However a summary of the
changes are as follows:
- Benefits data used as been amended to take into account the introduction of
Employment Support Allowance
- Mood and anxiety prescribing data is no longer available, so data for 2005 from the IMD
2007 has been used
- Key stage 2 and key stage 3 now uses the ‘level achieved’ as in the IMD 2004, rather
than actual test scores
- More accurate school absence data has been used
- A more effective modelling of incomes to calculate difficulty of access to owner
occupation
- Slight changes in Home Office counting rules for notifiable criminal offences, but overall
no substantive chances
- Houses in poor condition data has been used from the 2007 IMD, due to cost
considerations
Blackburn with Darwen results
There has been little change in the overall summary ranks between 2007 and 2010 for
Blackburn with Darwen. On the two overall summaries of deprivation, the ‘rank of average
score’ and the ‘rank of average rank’ the borough has become relatively less deprived.

# IMD 2007 summarised to 2009 local authority boundaries
* A positive number highlights an increase in relative deprivation, a negative number highlights a relative
decrease in deprivation.
There has also been a decrease of 5 places in relative deprivation on the ‘rank of income
scale’, but an increase in deprivation on the ‘rank of employment scale’. Both the employment
and income scores measure the actual number of people classified as being employment or
income deprived in the borough.
The comparable IMD 2007 identified that 12,422 people were classified as employment
deprived ranking the borough 79th. The IMD 2010 identified that there were 12,860 people
classified as employment deprived, ranking us as 75th.
For income deprivation, the comparable IMD 2007 identified 38,543 people as living in income
deprivation, ranking the borough as 65th. This number has now reduced to 33,691 improving
our relative rank to 70th.
The extent measure has remained the same at 14th in the comparable IMD 2007 and on the
IMD 2010. The Extent measure score identifies the proportion of the population living in the
most deprived areas in England. In 2004, 45% of the population of Blackburn with Darwen
lived within the most deprived areas in England, this increased to 52% in the 2007 IMD and
now stands at 51%.
There has been an increase in relative deprivation of two places on the rank of concentration,
moving from the 9th to the 7th most deprived authority. This measure reflects ‘hotspots’ of
deprivation.
Lancashire and AGMA results
Blackburn with Darwen remains the fourth most deprived local authority on the rank of average
score, of the AGMA and Lancashire district authorities.

A number of authorities have seen a worsening in their ranks on the IMD summaries. Within
the Pennine Lancashire area Burnley, Hyndburn and Pendle all saw increases in relative
deprivation on the two overall summary measures the ‘rank of average score’ and the ‘rank of
average ranks’. Ribble Valley and Rossendale saw considerable decreases in deprivation on
these two measures, whilst Blackburn with Darwen saw small improvements. Blackpool and
Tameside were the only two authorities in the Lancashire / AGMA area to see increases in
relative deprivation on all measures.
