French
Equivalent: Indice en chaîne  ISI 
Definition: 
An index number in which the value at any given period is related to a base in the previous period, as distinct from one which is related to a fixed base.

Context: 
The comparison of nonadjacent periods is usually made by multiplying consecutive values of the index numbers, which, as it were, form a chain from one period to another.
In practice chain index numbers are usually formed from weighted average of linkrelatives, namely the values of magnitudes for a given period divided by the corresponding values in the previous period.
