This study was aimed to investigate the roles of income and other socioeconomic variables such as household size, land size, head of household education level, raising the animals, source of income on food demand in rural Burundi. The needs for foods among the households in rural Burundi were examined using a recent survey done by the authors. An almost ideal demand system (AIDS) was laboring to evaluate the price and expenditure elasticities and the influence of socioeconomic variables on food demand products. An econometric model was then involved in analyzing the factors of food demand. The assessed expenditure elasticities for the food groups settled from 0.64 for oils to 1.36 for meats. The outcomes showed that there is a raised expenses elasticity for meats, fish, cereals and grains. The appraisal showed that the revenue and other socioeconomic variables exerted significant effects on food demand, and important expenditure elasticity for food group items will increase remarkably with rising income.
