SubRegionalization Handbook

Foundational Elements

A Note on Terminology

Sub-regional units go by many names internationally. When we refer to a sub-region in this document, we may use a variety of names to refer to the same entity. In IFs, there is a bias toward the use of “province” to refer to a sub-regional unit, but it is functionally equivalent to states, departments, territories, or any other name for a sub-regional unit.

Much of the following discussion will involve variables included in the model, such as GDP or POPULATION. These may be referred to as variable or series. The two terms are used interchangeably here.
