Looking again at the available resources, the situation remains as it
was when the earlier question arose: there is no "one good place" to
go for these types of figures. One has to ferret them out from the
individual companies, or one has to look through annual reports, or
buy a commercially prepared report for several thousand dollars. A
global picture of the market is simply too vast a project.

Aside from the Asian-Pacific companies mentioned (Australia, Japan, S.
Korea, China, Indonesia, Malayasia), the North American companies
(Canada, US), the Brazilian companies, the Scandinavian companies
(Finland, Sweden), the Russian companies, etc., all have to be taken
into account in their markets.

Good luck in your research.
