I know enough about your situation to know you aren ' t poor , based on any reasonable positive metric . If you are poor , 99 % of the world is poor . That doesn ' t seem reasonable , does it ? Not when there are actually people starving in the world . A gallon of milk in 1955 cost about . 92 cents adjusted for inflation , that equals about $ 8 . <| sep |> It ' s a wonderfully interesting map but I have one question , why did you chose the cities you did ? There are a lot of big gaps you could fill with unlabelled important cities , I ' m thinking Plymouth , Aberdeen , Leicester , Nottingham and Swansea . There is only one city representing the Midlands and there is also quite a SouthEast bias with you showing four cities from there . Two of which are considerably smaller than any other city on your map .
