Bloomberg published a fascinating list of 50 US cities with biggest exposure to poverty amongst their populations. The full list is available here: http://www.bloomberg.com/visual-data/best-and-worst/most-poverty-us-cities
Just to make exercise a little different, I grouped them into four main regions. One would expect the results to show South to have highest poverty exposures, the West showing relatively benign poverty, but due to high ethnic diversity and significant presence of minorities, somewhat higher poverty exposure than, say North-East… alas, here are the numbers in full glory.
Ranking in descending order: West shows lowest poverty exposures, followed by the South excluding Florida (different composition of population by age and ethnicity), and so on, until Mid-West comes out the worst, but only as long as we include the State of Michigan (Detroit and Flit being numbers 1 and 2 worst off cities when it comes to poverty).
