Published annually in May, the Yearbook complements the World Metal Statistics monthly report and provides annual figures for the previous year and the preceding nine years for easy comparisons.
The Yearbook features the full range of metals data; the six LME metals plus:
- Iron Ore
- Stainless steel
Prices data gives the annual average for the metals included in the monthly World Metal Statistics for the last ten years.
Data is researched and gathered from a pool of resources, including companies, government statistics and press reports. Trade data are a valuable source of information; the latest available statistics are collected direct from national customs for almost 120 countries.
Reported production by plants is compared with nationally reported data. Material flows and balances are calculated to ensure that the data are internally consistent.
Detailed usage is rarely provided by government agencies and so apparent consumption is calculated to produce a surrogate for reported demand:
PRODUCTION + IMPORTS – EXPORTS ± STOCK CHANGE = APPARENT CONSUMPTION
The publisher liaises regularly with other statistical agencies, international study groups and trade associations to keep up with changes in the industry structure.
