摘要：Section I outlines in-depth the whole-farm variables stored on the Farm Management Whole-Farm Data Bank, SAS Data File. This file currently contains 483 variables per farm for approximately 2,300 to 3,000 farms for the years 1973 through 1989. Subsequent years' data will be added to the overall file when made available. Other SAS data files will be developed from this comprehensive data bank, such as a file that contains only farms that have continuous data for a given period.
