  1. In the column Harmonization of statistical units (M1), “Population” means that income was collected in per capita terms using the total population of the corresponding AU; “Household” that the total income was divided by the number of households of the AU; “Total value” that income was provided in aggregate terms by the NSI and “Equivalised” that household income took into account the differences in size and composition of households. “Av.” stands for average and “eq.” for equivalised.
