Term	Definition
Administrative boundary	A geographic polygon or polygons representing the perimeter of one administrative unit.
Administrative heirarchy	A set of recognized and hierarchical levels of administrative authority and geographic partition of a country or territory. Increasing administrative level numbers represent lower (geographically smaller and administratively subservient) units, with administrative level 0 representing the entire country, administrative level 1 representing the next lower level, and so on. Afghanistan is divided into provinces, which are in turn divided into districts. Thus Afghanistan's administrative level 0 is the country (Afghanistan), administrative level 1 is the provinces, and administrative level 2 is the districts. In some countries an administrative level may consist of more than one type of administrative unit. The United States of America's administrative level 1 consists of States, the District of Colombia, and further remote units. Canada's administrative level 1 consists of provinces and territories.
