Retail Inventories Ex Autos MoM measures month to month change in United States retail stock excluding car dealers. It comes from the Census Bureau Monthly Retail Trade Survey of about 13000 employer firms selling to final consumers. The cut removes only NAICS 441 for car dealers, while gasoline stations and other retail kinds remain in scope. It tracks stock of unsold goods at cost, not sales, and feeds national output through national accounts in current dollars.
Dollar values stay in current dollars with no price adjustment, so moves mix price and volume. It excludes factory and wholesale stocks and food service stocks, which come from other surveys. It still includes gasoline stations and all other retail kinds besides car dealers.
