Though the farm share is incredibly small, and had been declining steadily since the initial report, in the past two years there was a slight bump that brought the farm share nearly back to 2000 dollars. Unfortunately, this bump from about 12 to about 14 cents is still well behind the 17-cent marker where this series began. (You can also think of these numbers as a percentage of the entire market share.)
You will note that the largest portions of our food dollar goes to two things - first, Food Services, which takes up about one-third of every food dollar we spend. Food Services includes "all eating, drinking, and related establishments" - in other words, places that serve ready-to-eat foods, like restaurants. Second is food processing, which includes any manufacturing business in the food and drink industry. It's also interesting to see how small a share of our dollars goes to energy, packaging, transportation, and advertising (included with legal fees in "other") - though these issues receive a lot of attention in the media.
Put most simply, it seems that Americans wanting to make the most out of their food dollars could save a considerable amount if they ate out less, and cooked at home using the least-processed foods possible.
