This annual report includes major time series that reflect changes in farm production, production inputs, and production efficiency. Time series data are presented for the United States and, in most cases, for 10 farm production regions. The text highlights changes since the previous year or specified time period. In previous reports in this series, data was revised for the year preceding the year in the title, but in this report, a new survey-based labor series on total hours has been incorporated, starting with the year 1947. As a result, all data series in the report start with 1947. By using data from the 1984 Farm Costs and Returns Survey, the report will help analysts assess more accurately the efficiency of farm labor hours. Seventy-two tables are provided. Representative topics include: farm production--indexes of farm output by enterprise groups, by region, by cropland used for crops by region, and by fertilizers; labor--by hours required in various enterprises, by indexes of farm production per required hour by enterprise groups, by region; and indexes of total farm input and major input subgroups by region.
