The deterioration of the economic base of the city has accelerated. There were an estimated 81,754 vacant housing units (22.2 percent of the total) in Detroit before the recession; that number increased to an estimated 101,737 (27.8 percent of the total) in 2008.
The average price of a residential unit sold in the January through November, 2009 period was $12,439, down from $97,847 in 2003. Remaining businesses and individuals are challenging property tax assessments on parcels that have lost value and, in some cases, cannot be sold at any price.
More than half of employed city residents work outside the city limits; the metro area has the highest unemployment rate of the 100 major metro areas in the U.S.
