The unemployment rate reached a 24-year low in November 2015 and stood at 10.0% . From 2012 to 2015 Berlin, as a German state, had the highest annual employment growth rate.

Educational System: The Berlin-Brandenburg capital region is one of the most prolific centres of higher education and research in Germany and Europe. Historically, 40 Nobel Prize winners are affiliated with the Berlin-based universities.

Geographical Situation: Berlin is in northeastern Germany, in an area of low-lying marshy woodlands with a mainly flat topography, part of the vast Northern European Plain which stretches all the way from northern France to western Russia. The Berliner Urstromtal (an ice age glacial valley), between the low Barnim Plateau to the north and the Teltow plateau to the south, was formed by meltwater flowing from ice sheets at the end of the last Weichselian glaciation. The Spree follows this valley now. In Spandau, a borough in the west of Berlin, the Spree empties into the river Havel, which flows from north to south through western Berlin. The course of the Havel is more like a chain of lakes, the largest being the Tegeler See and the Grober Wannsee. A series of lakes also feeds into the upper Spree, which flows through the Grober Muggelsee in eastern Berlin.
