Grocery retail sits within Retail & Consumer Goods, the final link between everything produced above and the person who actually uses it — a category whose own scale remains unverified (no global market-size figure could be confirmed against a primary source). Grocery retail is one of 8 of the category's 20 items directly backed by institutional trackers — US Census Bureau, UNCTADstat — rather than an editorial judgment call.
