A nation's geographic efficiency reflects the advantage or disadvantage that the shape and size of the nation give its ability to fight and develop effectively. A nation that is consolidated as one roughly uniform shape is much more efficient for purposes of communication and the transportation of troops and supplies than is a nation broken up in several seperate pieces, riddled with holes, or composed of unwieldy thin tracts. A nation's geographic efficiency will also suffer if the nation's area is larger than its supportable area (as displayed in the Nation Panel).

You should strive to keep your geographic efficiency at or close to 100% at all times. You can do this by occupying some areas and evacuating others, to give your nation a more uniform, efficient shape, and maintain an area that is sizable but not too large.

Another way to improve your nation's geographic efficiency is to develop technologies that increase your nation's Air Combat attribute. Effective transportation by air allows far-flung areas of a nation to work together better, improving the nation's overall efficiency.

Geographic efficiency, if neglected, can have a severe impact on a nation's performance. A nation with geographic efficiency of 66% is overall only two-thirds as effective as it would be with full 100% geographic efficiency.

Pictured below is the same nation spread out in various shapes, and the geographic efficiency that results from these shapes.

Geographic efficiency: 100%

Geographic efficiency: 85%

Geographic efficiency: 58%
