The food dollar series provides an overview of the food system, with estimates of the farm share and of the distribution of food-dollar value-added shares over time:
- For every dollar spent in 2012 in the U.S. on domestically produced food (food dollar), U.S. farmers sold 17.4 cents of farm products to non-farm establishments (farm share). After falling to 16.2 cents in 2009, the farm share of food dollar expenditures in 2012 rose to a level comparable to the 2007-08 level.
- Farm production costs per food dollar have increased in five of the past six years from 8.3 cents in 2006 to 9.7 cents in 2012. In previous years, agribusiness establishment costs were combined with farm production costs but are now reported separately.
- Wholesale trade costs per food dollar have declined in four of the past five years from 10 cents in 2007 to 9.3 cents in 2012. In previous years, wholesale establishments were treated as a subcontracting industry whose costs were allocated to other industry groups in proportion to services provided to each group.
- Energy costs per food dollar increased by 27 percent between 2009 and 2012 and were 5.6 cents per food dollar in 2012; this follows a decline of 35 percent from 2008 to 2009.
