34. Conclusions • Benefit of a regional classification for London • London has a very different geography to the UK • Caveats • May not be helpful in all contexts; loose comparability / augmentation potential • Some issue with the scale at which affluent neighbourhoods emerge - sub OA? • More work is needed on the delineation of regions - avoid suburban performance hit
