Deprivation
The middle postcode here sits in decile 7 of the English Index of Multiple Deprivation (2021-Census LSOAs), where decile 1 is the most deprived tenth of neighbourhoods and 10 the least. 8% of this district's postcodes sit in the most deprived three deciles, 44% 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.
