The eight English core cities outside London often work together on issues that affect them. One thing I've been looking at recently on some work in Sheffield is how the core cities compare in terms of patterns of deprivation. So, I've mapped and compared them below. Red areas are amongst the 10% most deprived in England and the darkest blue areas are amongst the 10% least deprived in England. The maps are at different scales but the point here is just to provide a quick visual comparison of cities in this map matrix view.
