What's New

In the Geography category for all countries, a review and updating of “Land boundaries” (lengths measured in kilometers) was recently completed. Additionally, a new ‘World’ land boundaries total was compiled that came to 279,035.5 km. This figure is actually misleading, however, since it is impossible to accurately measure every river meander along a boundary. A number rounded slightly higher – to 280,000 km – makes more sense and has been coordinated with and approved by the US State Department.
