French Equivalent: Additivité - IPC

At current prices, the value of an aggregate is identical to the sum of the values of its components.

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.
