DEPRIVATION INDICES

Indices of Multiple Deprivation
2.2.2 The NI 195 survey is designed to provide a ‘representative’ picture of cleanliness within an authority. More importantly, the survey enables local authorities to compare their performance with national benchmarks (produced annually by Defra’s Local Environmental Quality Survey of England - LEQSE), on a ‘like-for-like’ basis using ten standard Land-use Classes.
2.2.3 Use Of The 2004 Indices Of Multiple Deprivation
However, for the 2004 estimates of IMD published by the then Office of the Deputy Prime Minister (ODPM), the boundaries of the Low Level Super Output Areas (LLSOAs) were compatible with the prevailing Ward boundaries.
2.2.4 This enabled ENCAMS to make estimates of the IMD scores for Electoral Wards, which for most authorities could be aggregated to the Ward boundaries that existed at 31st December 2002, and which would be used for the 2003 local elections.
2.2.5 For a minority of authorities, the Wards used were those where a Statutory Instrument giving notice of changes to Ward boundaries had been published by 31st December 2002, and those changes were expected to be used for the 2003 local elections. Some Wards have been combined because of confidentiality restrictions imposed by the Office for National Statistics.
2.2.6 Authorities can download the estimated IMD scores for Wards in their District by clicking on the appropriate Regional file below, and printing the page(s) that relate to their District.
2.2.7 Important Note
These IMD scores have been aggregated from LLSOAs to Wards solely for the purpose of planning the NI 195 Survey. The method used is simple and does not include, for example, weighting based on population size. The results are not approved by the National Statistics office and should not be used an an official measure of the 2004 IMD at Ward level.

2.2.8 Use Of The 2007 Indices Of Multiple Deprivation
If authorities feel that they wish to use the 2007 IMD figures together with their current ward boundaries, then if they have access to computerised Geographic Information System (GIS) facilities they may be able to do so in the following way:
a. obtain a set of the 2007 IMD information for the authority by sending an email order to communities@twoten.com. (General enquiries should be sent to indices.deprivation@communities.gsi.gov.uk);
c. obtain a CD containing the digitised boundaries of the Lower Level Super Output Areas (LLSOAs) within their authority, using the order form obtainable at the following Office for National Statistics website. This website also gives further information about the SOA boundaries.

Please note that the SOA boundaries are only available as a standard product for the whole of England and Wales, not just for individual authorities.

If using MapInfo software, authorities should request a Mid/Mif file. If using ESRI software (e.g. ARCINFO), authorities should request a shapefile. The order form, with a covering email, should be sent to ons.geography@ons.gov.uk.
c. create a file within their GIS that contains the digitised boundaries of the current electoral wards;
d. overlay the LLSOA boundaries for the authority over the electoral ward boundaries, and assign each of the LLSOAs to the appropriate electoral ward;
e. make appropriate adjustments where LLSOAs are split between electoral wards;
f. add together the IMD scores for the LLSOAs within a ward, and divide the total by the number of LLSOAs.
2.2.9 This will give an estimate of the IMD for each electoral ward. Rank the electoral wards within the district according to their estimated IMD figure. The resulting list of wards may then be used to help plan the NI 195 survey in the manner set out in this Manual.
2.2.10 Maps of Electoral Wards To Which the IMD Figures Relate
Within each local authority the Electoral Registration Office (or the Chief Executive’s Department) should be able to provide a map showing the District’s Electoral Ward boundaries which relate to the estimated 2004 (or 2007) IMD scores.
