The Berlin/Brandenburg metropolitan region or capital region is one of eleven metropolitan regions of Germany, consisting of the entire territories of the state of Berlin and the surrounding state of Brandenburg. The region covers an area of 30,370 square kilometres with a total population of about 6 million.
The metropolitan region should be distinguished from Berlin's immediate agglomeration, dubbed Berliner Umland which comprises the city and the nearby Brandenburg municipalities. Berliner Umland is significantly smaller and much more densely populated than the metropolitan region, accounting for the vast majority of the region's population over a fraction of its total land area.
