The middle postcode here sits in decile 8 of the Welsh Index of Multiple Deprivation, Wales's own separate index, where decile 1 is the most deprived tenth of neighbourhoods and 10 the least. 6% of this district's postcodes sit in the most deprived three deciles, 58% in the least deprived three.
Deprivation deciles describe the LSOA neighbourhood each postcode sits in, weighted by postcodes rather than by people, because the postcode file carries no population. A district where the deprived neighbourhoods are densely populated will read better here than it would per resident.
