The DAFNE databank is based on information collected in the context of the nationally representative household budget surveys (HBS), which are regularly conducted by the National Statistical Offices. The HBSs collect data on all goods available to the household members (including purchases, own production and payment in kind), as well as on the socio demographic characteristics of households and individuals.
