When using postcode analysis, SIMD 1 is listed as being most deprived and SIMD 5 being least deprived.
Using the SIMD look-up, two potential responses may occur:
1 SIMD area eg SIMD Area 5
2 No SIMD for this postcode
Reasons for no SIMD being returned are:
- new postcodes that have note been assigned an SIMD value as yet
- this postcode does not exist
- no deprivation information attached to the postcode.
If there is not an SIMD value, then claim the codes linked to SIMD 4-5 only.
