Economy-
Before the reunification of Germany and the two Berlin parts in 1990, the city of West Berlin received substantial subsidies from the West German state to compensate for its geographic isolation from West Germany. Many of those subsidies were phased out after 1990. The reduced financial support for the city and its gradual economic decline have produced fiscal difficulties for Berlin's city government and forced it to cut funding for various programs. The current unemployment rate remains therefore above the German average at 16.1% as of November 2006.

Unemployment and poverty figures are higher than the national average in Berlin.
The gross state product of Berlin totaled €79.6 ($95.5) billion in 2005 and compares with €77.4 billion in 1995.
