Interesting , have seen something like this before, i think on a council website . Listed the areas with data about income etc , the lower income areas in my area match the quintile 1 , My town is surrounded by villages and they are all in band 5. Shame, your future looks so bleak if you live in certain areas , less than 12% . These areas have the highest crime , anti social crime , drugs etc even the fire and ambulance service had to have a police escort , not much hope for those who grow up there ,
