Figures have been supplied by governments through national publications and FAO questionnaires ( both paper or electronic). To make the coverage of this data collection as complete as possible, official data have sometimes been supplemented with data from unofficial sources. Use has also been made of information supplied by other national or international agencies or organizations.
Data on meat, milk and eggs relate to calendar years, with a few exceptions. Israel and New Zealand, for example, give data for meat production for years ending 30 September, and Australia for years ending 30 June. Milk production data shown for Australia refer to years ending 30 June and for New Zealand, to years ending 31 May.
