Equivalent: Additivité  IPC 
Definition: 
At current prices, the value of an aggregate is identical to the sum of the values of its components.

Context: 
Additivity requires this identity to be preserved for the extrapolated values of the aggregate and its components when their current values in some period are extrapolated using a set of interrelated quantity indices; or, alternatively, when the current values of an aggregate and its components in some period are deflated using a set of interrelated price indices.
