Seasonal Adjustment

Seasonal Adjustment
   An adjustment made to certain economic indicators to allow for predictable peaks and troughs caused by seasonal factors. Seasonal adjustment to an economic indicator makes it easier to discern the underlying trend. Adjustment is made by deducting an average of the change in a set number of previous years from the current change, showing whether a rise or fall is unusual or purely seasonal.
