CHAIN INDICES - SNA

Statistics Directorate    
French Equivalent: Indices-chaîne

Definition:
Chain indices are obtained by linking price (or volume) indices for consecutive periods; the short-term movements which are linked are calculated using weighting patterns appropriate to the periods concerned.

Context:
An index number series for a given aggregate spanning a long sequence of periods obtained by linking index numbers spanning shorter sequences of periods, each with their own weights. The linking may be made as frequently as the weights change and the data permit, or at specified intervals, such as every 5 or 10 periods. In the limit, the weights may be changed each period, each link in the chain consisting of an index comparing each period with the previous period.
