Known metadata gaps
Recorded explicitly rather than guessed.
- doi is null: the annual chapters carry no DOI of their own.
- Lineage is unresolved by design: the chapter assembles figures from many trade, industry and government reporters, most unnamed within it, and adds the survey's own estimates.
