Americans’ spending on food— proportional to income — declined dramatically between 1960 and 2007, according to a chart recently published by the United States Department of Agriculture (USDA), Economic Research Service (ERS).
As the chart shows, the average share of per capita disposable income spent on total food on average decreased from 17.5% in 1960 to 9.6%. “The share of income spent on total food began to flatten in 2000, as inflation-adjusted incomes for many Americans have stagnated or fallen over the last decade or so. In 2014, Americans spent 5.5 percent of their disposable personal incomes on food at home and 4.3 percent on food away from home.”
