Definition: Seasonally adjusted component of a time series
OECD - Data and Metadata Reporting
Result of the extraction of the seasonal component (including the calendar effects component) from a time series. If neither seasonal nor calendar influences are present in the original data, the seasonally adjusted series is given by the original data.
For series with no identifiable seasonal variations but with identifiable calendar variations, the seasonally adjusted series is given by the calendar adjusted series.
