Disadvantage: Greater London

Volume 508: debated on Thursday 25 March 2010

To ask the Secretary of State for Communities and Local Government what the value was of each indicator in the (a) income, (b) employment, (c) health, (d) education, (e) barriers to housing and services, (f) crime and (g) living environment domain of the indices of deprivation for each London borough in each year since 2000. (323775)

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


Employment Deprivation


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.
