  ●  Removal of Nonemployers

Previously in the Annual Retail Trade Survey, firms without paid employees, or nonemployers, were included in the estimates through imputation or administrative data provided by other federal agencies. In addition to the 2017 North American Industry Classification System (NAICS) changes, the Annual Retail Trade Survey restated data to include employer-only time series to be aligned with the Annual Integrated Economic Survey (AIES).  The change impacts the following tables:

• Sales (1992 – 2022)
• Sales Taxes (2004 – 2022)
• Inventories  (1992 – 2022)
• Purchases  (1992 – 2022)
• Gross Margins (1993 – 2022)
• Per Capita Sales (2000 – 2022)
• U.S. Retail Trade Sales - Total and E-commerce (1998 – 2022)
• Sales for U.S. Electronic Shopping and Mail-Order Houses (NAICS 4541) - Total and E-commerce by Primary Business Activity (2015-2022)
