FAQ

How are seasonally adjusted estimates derived?

We used quarterly e-commerce sales estimates for 4th quarter 1999 through the current quarter as input to the X-12 ARIMA program to derive the adjusted estimates. Additional information on the X-12 ARIMA program may be found at the X-12 ARIMA website.

For more information, visit the Monthly and Annual Retail Trade website.
