Why is it important?

Seasonal adjustment is proving to be very challenging during the COVID-19 crisis. Poor seasonal adjustment practices may result in providing false signals on the state of the economy, as well as resulting in large future revisions.

Perspectives

It is important that statisticians provide users of official statistics high quality, reliable time series statistics in real-time . Seasonal adjustment plays a critical role in this process.
