The pattern of food consumption can be used as an indicator in looking at the level of community welfare and regional typology is an important determinant that helped determine the pattern of household food consumption, because the consumption patterns associated with behavior that cannot be separated from the socioeconomic cultural and environmental conditions. This study aims to (1) analyze the impact of socio-economic conditions on household food consumption patterns in urban and rural areas and (2) to estimate the elasticities of urban and rural food consumption in East Java in response to changes in prices and income. The micro household data from Susenas 2016 is used to answer the objective by using the demand system model of Linear Approximation Almost Ideal Demand System (LA/AIDS). The results showed that the socioeconomic condition generally influenced in determining the pattern of household food consumption, where the pattern of food consumption in urban areas tended to prioritize food consumption with better nutritional value than rural areas. While based on the value of elasticities, food commodities in East Java are still a necessity, households in rural areas are generally more responsive to both price changes and income changes than urban households.
