Ranked by real-world weight
Each item below is marked sourced (a real institution tracks or ranks it) or judgment (no such institution ranks it โ included on domain knowledge, not fabricated data).
Deloitte's Global Powers of Retailing ranks companies, not retail
sub-sectors, so it doesn't substantiate this list. Instead, the US Census Bureau's Monthly/
Advance Retail Trade Survey directly tracks 7 items by NAICS code: E-commerce (1, Quarterly
Retail E-Commerce Sales, corroborated by UNCTADstat's e-commerce theme data), Grocery retail (2,
NAICS 4451), Consumer electronics retail (4, NAICS 443), Apparel & footwear retail (7, NAICS
448/4482), Big-box & department stores (8, NAICS 452), Pharmacy & drugstore retail (9,
NAICS 44611), Warehouse clubs (18, NAICS 452311). The Census Monthly Wholesale Trade Survey
tracks Wholesale distribution (12) โ though "cash & carry" specifically has no NAICS code of
its own. FMCG, personal care, household products, luxury goods, DTC, convenience stores,
furniture, toys, pet products, discount stores, duty-free, and online marketplaces have no
single institutional category isolating them and stay editorial.
