122 local authorities in England contain at least one of the 1,370 deprived housing estates. This research acknowledges that an Index based on these six indicators can only provide a partial measure of deprivation. Similarly it may also be that this Index is more sensitive to the differences in built form between different areas of the country than when the full 13 indicators are used. Ideally in a study of local authority estates information about the condition of the housing and environment should be available, but unfortunately there is no data of this kind available for all EDs. Despite the limitations, the six factors are the best information available at the very local level which is required for a study that focuses on estates.
Some estates comprise only one ED, but most contain more than one.
Non-deprived EDs were included if they formed part of the estate. A single deprivation score for each estate was calculated using the deprivation scores, from the Index of Local Conditions, for each ED comprising the estate.
