Sanitation access (3.4B lack safe access) sits within Water, the item more essential than any traded good, yet the least marketized on this list — a category with a real, cited scale: $1.04T infrastructure investment need for universal water access and sanitation by 2030 (World Bank). Sanitation access (3.4B lack safe access) is one of 14 of the category's 20 items directly backed by FAO AQUASTAT, WHO/UNICEF JMP, UN Stats SDG indicators, ICOLD, and the International Hydropower Association's tracked datasets, rather than an editorial judgment call.
