I saw this research in CYPNOW - Youth club study highlights link to most deprived areas

They have a subscription policy, so you may or may not be able to read it!  First few paragraphs:

 A quarter of all local authority-funded youth centres and clubs are located in the 10 per cent most deprived postcodes in England, a CYP Now study has found. Almost half are located in the 30 per cent most deprived areas of the country.

CYP Now analysed the locations of 710 youth clubs and centres from 25 local authorities of varying sizes against the government's Indices of Multiple Deprivation (see table below).

The snapshot, which was taken from 95 council responses obtained under the Freedom of Information (FoI) Act, revealed that while most of the 25 local authorities examined were able to fund some level of youth provision in more affluent districts, the majority of youth clubs were located in less well-off areas.

In Leicester, for example, 54 of its 67 council-funded clubs or centres were located in areas ranked in the top third of deprivation.

There are some questionable figures presented - particular around the mix of "youth club" and "youth centre" it seems - therefore the calculations made might not be comparable

If you work in one of the areas cited, maybe check if the figure for local-authority funded provision is correct.  I know from tomorrow in Manchester, that figure will go down to zero...
