INPS (UniEmens) data processed by CNEL: yearly average of the twelve monthly returns. For agricultural agreements the figure is partial (only permanent workers, clerks and executives). For domestic work it is the average of quarterly returns, only for agreements with the INPS convention on bilateral bodies. For the public sector CNEL uses the State General Accounting Office annual account. In the CNEL files a 0 may mean that no figure was provided for that year: zeros before the first positive value are shown as not available.
