The HEIS's linkage of household-level demographic and expenditure data for Zambia provides the foundation for an analysis of household expenditure patterns. For this report, total household expenditure was composed of two broad expenditure classifications, food and nonfood. An analytical emphasis was placed on developing the food expenditure patterns of household groups identified by various socioeconomic characteristics. In general, within the various household classifications, there were three important economic variables: the availability of food items within specific markets, household income, and relative prices that appeared to contribute to the development of the observed food group expenditure patterns. Directly observable, absolute differences in total expenditure, shares of total expenditure, and shares of total food expenditure were used to distinguish groups of households.
