The indices of deprivation 2007 and 2004 (ID 2007 and ID 2004) were constructed at Lower Super Output Area (LSOA) level. LSOAs are consistent in size and over time, and allow identification of small pockets of deprivation. This also overcomes difficulties in producing statistics for electoral wards associated with frequent boundary changes. There are 32,482 LSOAs in England.
Domains within the Indices of Deprivation are independent dimensions of multiple deprivation, each with their own impact on multiple deprivation relative to its importance. In the ID2004 and ID2007 the overall IMD was constructed by combining the individual domain indices using explicit weights, driven by theoretical considerations and research into the issue of weighting carried out by the University of St. Andrews (Dibben et al., 20071). The weightings are as follows:
Domain weight (percentage) Income Deprivation 22.5 Employment Deprivation 22.5 Health Deprivation and Disability 13.5 Education, Skills and Training Deprivation 13.5 Barriers to Housing and Services 9.3 Crime 9.3 Living Environment Deprivation 9.3
Domain weight (percentage)
Health Deprivation and Disability
Education, Skills and Training Deprivation
Barriers to Housing and Services
Living Environment Deprivation
Six summary measures of the Indices of Multiple Deprivation 2007 and 2004 have been produced at both local authority district and unitary authority levels. The summary measures at district level focus on different aspects of multiple deprivation in the area. The six measures are Average Score, Average Rank, Extent, Local Concentration, Income Scale, and Employment Scale.
