This study analyses seafood consumption at home in Spain using three different cross-sectional survey data-sets for 1980, 1990 and 1998. Households are analysed in eleven different types, according to size and composition. Price indices for seafood and meats are calculated for each household type. Discrete participation and continuous consumption decisions are studied. Socio-economic variables sometimes play an important role but not with a regular pattern. Economic fundamentals follow a common pattern for all household types. Seafood demand is inelastic in 1980 and very elastic and meat complement in 1990 and 1998. Expenditure elasticity does not decrease between 1980 and 1998.
