Historical Track Records: Crop Production, April 2012

摘要

These track records of United States Crop Production were assembled to serve as a ready reference for data users. The track records are comprised of National level statistics for the principal crops in NASS' estimating program. The following data, as applicable, are presented for each of the crops: Historic estimates of acreage, yield, production, price, and value. Comparisons of preliminary and final planted and harvested acreage estimates. Comparisons of yield forecasts versus end-of-year and final yield estimates. Comparisons of production forecasts versus end-of-year and final production estimates. Commodity estimates for 2008, 2009, 2010, and 2011 are not considered final until the after the 2012 Census of Agriculture. Therefore, the columns titled Percent of final are a percent of the estimate published in the annual summary or the latest revision for 2008, 2009, 2010, and 2011. The crop estimating program reports on farmers' planting intentions, estimates of acreage actually planted and expected to be harvested, and forecasts of yield and production during the growing season. After the crops have been harvested, estimates of harvested acreage, yield, and production are made. Through the mid-year and other quarterly probability surveys, information is collected on acreage, yield, production, and grain stocks on farms. Surveys conducted between quarters are used to gather information on crop conditions and yields.
