Coverage
Data coverage notes
- no dataNo commodity-decomposed recycling data - No USGS MCS Fig13 scrap rows. EU WEEE / battery EOL flows (Phase 6.1.1) are country-keyed only - see country profiles.
- datedExport-restriction inventory ends 2020 - The OECD industrial-raw-materials inventory (vendored snapshot) reports HS-line measures only through 2020; restrictions enacted since are not reflected in the measure table.
- narrowConsumption geography is single-economy (United States) - Reported consumption covers one economy only - the world usage split must be read from trade flows, not from a consumption table.
Methodology
How strata reads a commodity
The eight-stage lens, the observed-vs-estimated membrane, stage-honest supply, per-stage concentration, ownership resolution and the demand lens - the full method is illustrated live on copper, nickel and lithium.
Provenance
Where this data comes from
- BGS World Mineral Statistics
- Brazil ANM Anuário Mineral Brasileiro
- Ghana Chamber of Mines 'Mining Industry Statistics and Data' Factoid (free public PDF) - archived via `strata gh-chamber pull`; Appendix A1 parses to single-operator bauxite (Ghana Bauxite Company) + manganese (Ghana Manganese Company) production, the sole national producer of each.
- Guinea MMG mining-statistics bulletins (Ministry of Mines / INS, free PDFs) - archived via `strata gn-mmg pull`; the bauxite per-société tables parse to named-company production + export SupplyRecords (the aluminum supply-chain origin: CBG, SMB, GAC, CHALCO...).
