Trade Yearbook 1970 [antikvár]

GENERAL NOTES ON THE TABLESAcknowledgement and source of dataThe publication of this Yearbook has been made possible by the cooperation of the governments which have supplied most of the information. FAO is grateful to governments and to international and other organizations for their cooperation in helping to compile the basic statistics used in preparing this volume.As a general rule, figures for the most recent years have been supplied by governments, either through their national publications or through FAO questionnaires. In addition maximum use is made of the computer tabulations provided by the Statistical Office of the United Nations. In an effort to make the coverage of the Trade Yearbook as complete as possible official trade data have sometimes been supplemented with data from unofficial sources. Use has also been made of trade information supplied by other national or international agencies or organizations.In the absence of any reliable sources or when information for the latest year is not available in time, figures for quantities and values are estimated on the basis of trade returns of trading partners. Details of statistics derived in the above manner for Afghanistan, China (mainland), Eastern Germany, Korea (North), Mongolia, Romania, and Viet-Nam (North) are shown in Supplementary Economics Statistics.In a few instances, when information is available in terms of quantities only, corresponding values are estimated using average regional unit values or unit values for the preceding year.All figures estimated by FAO are marked by the symbol' and should be used with caution.In comparing data for years covered by this Yearbook with data for earlier periods in preceding issues attention should be paid to the relevant notes in the yearbooks concerned.Some figures for a number of countries require explanations or qualifications which are essential for proper interpretation of the data. Cases in which international comparability over the years covered by this Yearbook could not be achieved are indicated below and in the Commodity Notes.Additional tables and changes from the 1969 issue of the YearbookThree new tables were added to this issue of the Trade Yearbook: Malt (Table 39), Tomatoes (Table 56) and Natural Honey (Table 62).
