It is unclear what year this map is from, but my guess is around 2009. The map includes Detroit Future City (DFC) demonstration areas which would have come at the beginning of the DFC process. The map demonstrates how there Detroit’s core has been devoid of development and strong neighborhoods which in turn caused the population to move to the outer edges of the city or to move out of the city all together. Most telling is the “steady” distinction along the Woodward corridor surrounded by a sea of red “distressed” areas.

Detroit Free Press can we get a year reference on this data?
