Data Sources
Commodity pages identify the publications used for their displayed series. Every commodity series uses extracted USGS, EIA or World Bank tables. World Bank data carries source-specific CC BY 4.0 attribution and links to its dataset terms. Uranium uses EIA spot-contract purchase averages. Coverage and price definitions differ by commodity.
