Determinants of consumption patterns of elderly couple and elderly single were investigated using the 1996 National Survey of Family Income and Expenditure by National Statistical Office. There were large differences in consumption patterns between the elderly couple and single in terms of monthly expenditures and average budget shares of individual consumption items. Consumption functions of individual items were estimated using double-log function. Major determinants of consumption functions were income, overspending behavior, educational level of householder, and net worth for both groups, householder's job status and city residence mainly for elderly couple, and age of householder mainly for elderly single. In addition, income elasticity of elderly households was larger than net worth elasticity for all consumption items.
