Technical notes

The technical notes, prepared by external survey companies, are available from 1965 to 1984 (with the exception of 1968, 1969 and 1971, for which the notes are not available).

For the years after 1984, the technical notes are published in the Supplements to the Statistical Bulletin - Survey on Household Income and Wealth.

For the pilot surveys (1961-1962) please refer to the section Miscellanea (Italian version).

The historical documents are available only in Italian.
