BASE PERIOD

Statistics Directorate    
French Equivalent: Période de base

Definition:
Base period is the period of time for which data used as the base of an index number, or other ratio, have been collected. This period is frequently one of a year but it may be as short as one day or as long as the average of a group of years.

Context:
In the System of National Accounts (SNA) 1993, par.16.16, the base period is described as the period that provides the weights for an index.

Under the SDDS, this refers to the period when the published index = 100, or the reference period to which the average level and/or constant price series data refer.
