The annual revision is conducted each spring at about this time. The source provides a full explanation of the extent and method of the revisions (citation). The pre-revision values are not available through Data Buffet.
The revisions apply to these six mnemonic patterns representing distinct subsets:
- XRT?.IUSA = Retail and food services sales, NSA
- RT?.IUSA = Retail and food services sales, SA
- XRI?.IUSA = Retail inventories, NSA
- RI?.IUSA = Retail inventories, SA
- XRIS?.IUSA = Retail inventories/sales ratios, NSA
- RIS?.IUSA = Retail inventories/sales ratios, SA
The official scope of the revisions is (citation):
- Monthly sales, NSA - from January 2008 through February 2017 (March 2017 if part of the Advance set)
- End-of-month inventory, NSA - from January 2005 through February 2017
- Quarterly e-commerce sales - from 1999Q4 through 2015Q4 (will be disseminated on May 17, 2017)
We observed revisions as far back as the following, but the most pronounced revisions apply to the most recent years, from 2015.
- Monthly sales, NSA - from January 2008
- Monthly sales, SA - from June 2005
- Inventory, NSA - from January 2005
- Inventory, SA - from April 2002
- Ratios, NSA - from October 2005
- Ratios, SA - from October 2003
We also updated our two SA supplement series, RT452111X.IUSA and RT452112X.IUSA.
