Past studies of household food expenditure suggest that the effect of income on expenditure varies among households of different sizes and in different urbanization and region categories. No systematic investigation has been made, however, of these or other interactions among the independent variables used to explain household food expenditures. In this study, data from the 1955 USDA Household Food Consumption Survey are examined through the use of a special program developed by Sonquist and Morgan for the detection of interaction effects. Important interactions affecting expenditures for food and beverages consumed at home were found between household size and income, between household size and urbanization, and among household size, urbanization, and income.
