This section records the relation to productive activity of the population resident in family households as well as the changes produced in their work situation and estimates the degree of participation of the population in economically non-productive activities. The annual Labour Market Census operation (CMT) - Supply sets out to collect information on the labour force made up of the population aged over 16 resident in family households, both to estimate the large aggregates of the labour market and to obtain an approximation to the existing sectorial and socio-professional structure.
