A model is estimated for the decision of participating in the labour market for different groups of household members: not coupled (single, divorced and widow) women and men and coupled (married and in permanent union) women and men. The differences among these groups are significant. Probit models are estimated for the period 1984 : 1-2000 : 4 using the National Housing Survey. The neoclassical static model performs fairly well in describing the empirical determinants of the decision of participating. In terms of sign and significance of estimated coefficients the best performance of the model is reached for women. In terms of prediction the model proves useful for not coupled persons. Except for the variable named 'children aged less than six years', all variables perform well.
