The understanding of consumption patterns of the households of different income groups is essential for the development of successful food security policies. In recent years the studies on consumption patterns had a special focus in the wake of globalization and concern about food security. Empirical information on the determinants of household consumption is necessary both for macro-economic policy as well as for micro-level interventions to improve the nutrient intakes. The present study has been an attempt in this direction. The purpose of this study is to examine the consumption pattern of households in West Bengal. This study reveals that the elasticity of per capita consumption expenditure on food items and non-food items are less than one and more than unity respectively in all income groups. This explain that the proportion of per capita total expenditure incurred on food items declines with the increase in total per capita expenditure and the proportion of per capita total expenditure incurred on non-food items goes on increasing with the increase in per capita total expenditure across the sample households in all income groups.
