A negative binomial model was used to study the relationships between food expenditures, household characteristics, and the demand for different food items. The results show that increases in food expenditure increase the number of food items consumed at home, and the number of food items consumed at home is positively related to increases in the number of household members. This change in the number of food items consumed at home increases at a decreasing rate as household size increases and becomes negative when household size becomes large.
