The English indices of deprivation have, since 2004, been produced at lower level super output area (LSOA) level. LSOAs are smaller than wards and are designed to remain consistent in size, and over time, to allow more detailed identification of pockets of deprivation. There are 32,482 LSOAs in England with an average population of 1,500 people.
The indices are presented by ranking each area to show relative, rather than absolute levels of, deprivation. LSOAs are ranked from 1, most deprived, to 32,482, least deprived.
There are a selection of local authority level summary measures. The majority of the domains, and all the underlying indicators, are only published at LSOA level. For full details I refer to the publications on the Communities and Local Government website, as follows:

Before this, the indices were produced for each electoral ward in England. Indices of deprivation 2000 ward summaries can be found at:
