Analysis
NAICS 44911 is the 2022 NAICS industry for furniture retailers, part of 4491 (Furniture and Home Furnishings Retailers).
It has only one more detailed code, 449110, which covers exactly the same activities; the definition, index entries and statistics are on that page.
County Business Patterns publishes no national count for it, either because the code is out of the survey's scope or because the figures are suppressed to protect individual businesses.
