The report found that between 2003 and 2004, per capita spending on food in US urban areas rose from $2,035 to $2,207. "This change reflects increases of 7.9 percent in at-home food expenditures and 9.3 percent in away-from-home food expenditures," said the USDA. "Over the same period, per capita food expenditures as a share of total income in urban areas dropped from 9.8 percent to 9.5 percent." In 2003, US urban households with incomes in the lowest quintile (bottom 20 percent of the income distribution) spent $1,769 per person for total food, or 37.3 percent of total household income. Households in the highest quintile spent $2,737 per person for food, or 6.6 percent of total household income. Wealthier households, however, spent more of their food budgets on away-from-home food than other households. In 2003, urban female-headed households with children spent $1,610 per person for total food, of which 66 percent was devoted to food at home. Married couples without children spent $2,740 per person on total food, of which 60 percent was devoted to food at home. Food spending is one measure of household wellbeing. To assess that measure, USDA periodically publishes information on nationwide food expenditures, with data presented by selected demographic and socioeconomic characteristics. USDA tabulations are based on the most recent and comprehensive data available on at-home and away-from-home food spending by US urban households. The department said that policymakers and others concerned with how US households allocate their food dollars can benefit from having access to concise, easy-to-use information that details food expenditures by demographic and socioeconomic characteristics. "Such information could aid, for example, in the comparison of USDA food plans, such as the Thrifty Food Plan, with actual household expenditures," it stated in its summary of the report. "Such information could also provide a means to quickly determine per capita food expenditures by income group as well as the proportion of income spent on food by each group. Likewise, the information allows for comparisons of at-home and away-from-home food expenditures by numerous economic and demographic variables." In 2004, urban one-person households spent more than twice as much per person on food as households of six or more persons. Smaller households also spent a much larger share of their food budget on food consumed away from home than larger households. As the age of the head of the household increased, so, too, did urban per capita food expenditures in 2004. Once the head of the household reached age 64, however, per capita food spending started to decline. Households headed by persons age 55-64 spent the most per person on food consumed away from home. Among all US regions, urban households in the Northeast spent the most on total food per person in 2004, while urban households in the South spent the least. These rankings hold for away-from-home food expenditures as well.
