Geographic levels
In geography, different geographic (scale) levels are distinguished:

The local scale level relates to a small area, usually a city or municipality;
The regional scale level relates to a larger area, usually a region, state or province;
The national scale level relates to a country;
The continental scale level refers to a continent;
The global scale applies to the entire world;
The fluvial scale level relates to river basins (this scale level is mainly used in the context of pollution, for example).Within geography the use of geographic levels is also known as scales of analysis. An area of several countries (such as the Middle East or West Africa) is sometimes counted under the continental scale level, sometimes under the regional scale. Actually, both are incorrect, because it does not include a continent but is larger than a country, while the regional scale is smaller than the national scale. Sometimes the international scale level is also used for this, but this term is not in general use.
