Abstract
This paper examines the impact of selected socioeconomic characteristics on aggregate and group food expenditure patterns of racially different low-income households. A double logarithmic functional form was used to explain responses in household food expenditures to socioeconomic factors. Household income, family size, and Food Stamp Program participation were found to exert a strong positive impact on food expenditures. The general educational level of the homemaker registered no significant impact on household food expenditures. However, the nutritional knowledge of the homemaker increased the efficiency of food purchasing activities.
