- Differences in data and formulation mean that the 1998 and 2000 indices of deprivation are not readily comparable.
- The chart indicates that only 13 (26 per cent) of the unitary authorities/local authority districts which were identified as being amongst the 50 most deprived in 1998 were no longer amongst the 50 most deprived in 2000. However, it is not clear whether the changes in status shown are due to better data or represent real changes in the status of authorities, and the extent rank measure shown here is only one way (of several) of measuring deprivation.
