A new report from the USDA reveals the economic underpinnings of our food system.
The report slices the food dollar three different ways, to shed light on "different aspects of evolving supply chain relationships." The most straightforward data set, pictured above, shows that in typical dollar’s worth of US-produced food, 84.2 cents pays for food marketing, while just 15.8 cents is spent on the raw farm commodities themselves.
"Food marketing," in the USDA's definition, is not limited to advertising: It refers to the entire system that links farms to consumers, including transportation, processing, and distribution. In other words, the infographic above means that we spend five times as much on getting our food from farm to table as we do on actually growing it.
Overall, the USDA's report noted that the farm share component of food dollar expenditures has decreased steadily over the past twenty years, from just over 18 cents in the early nineties when this analysis began. Digging deeper into the numbers, the report's authors conclude that this decrease is due to a rise in eating out. The more we spend on paying others to cook dinner and clean up behind us, the smaller the proportion of our total food dollar that goes to the farmer:
These results present a compelling case that the growing costs and expenditures of eating out are behind the downward trend in the farm share value over the study period. Under this interpretation of the data, the added costs of food preparation and cleanup services in foodservice establishments are driving up the marketing share and driving down the farm share.
And in their conclusion, the authors predict that this is a trend that their projections indicate will likely continue:
Farm commodity prices are projected to initially lose ground for a few years on retail food prices and then to keep pace through most of the next decade. Food-away expenditures are forecast to outpace at-home expenditures over this period. Both sets of projections point to a falling farm share measure.

It's a lot to wade through, but well worth it—following the flow of dollars through our food system is one of the clearest and most thought-provoking ways of understanding the vast, distributed infrastructure that we rely on to feed us in the 21st century.
