The Index of Multiple Deprivation (IMD) is the official measure of relative deprivation.
The index is based on 39 separate indicators across seven distinct domains (Income; Employment; Health and Disability; Education, Skills and Training; Crime; Barriers to Housing and Services; Living Environment) to provide an overall measure of multiple deprivation and is calculated for every neighbourhood.
The index is relative rather than an absolute scale and so a neighbourhood with a score of 10 is more deprived than one rated 20, but this does not equate to being twice as deprived.
Please note: Different indices are used in England, Scotland, Wales and Northern Ireland and so comparison of scores from neighbourhoods in different countries should not be undertaken.
These figures report on incorporated UK companies only that are registered at this postcode and do not include sole-traders, partnerships or overseas organisations.
The population figure shown for your area are an estimate provided by the Office for National Statistics and is rounded to the nearest 1,000.
The estimates are derived from the Annual Population Survey (APS) which is the Labour Force Survey (LFS) plus various sample boosts.
