Data are based on the results of the quarterly Household Labour Force Survey which takes place all the thirteenth week of the quarter. The sample is drawn in two stages, first municipalities and then registered households. The sample was doubled in April 1990 from 12,000 to 24,000 households.
In the new survey, the coefficients used to estimate the population from the sample were modified; a new process is used for controlling and correcting errors. Annual data are averages of quarterly figures.
Data refer to persons aged 15 years old. The reference population comprises all household members present and resident in Italy and enrolled at local municipal registry offices. Institutional population such persons permanently living in hospices, orphanages, religious institutes and communities, barracks and similar are not included in the survey. Career military personnel are included in total employment using information obtained from their relatives living in private households. Conscripts are excluded from Labour force computation.
Series breaks: In October 1992, changes were introduced in the Household Labour Force Survey concerning the lower age limit of the active population (from 14 to 15 years old), the definition of unemployment, the population estimates, the estimation procedure and the imputation procedure. These changes resulted in a reduction in level estimates for employment and unemployment. In January 2004, major changes were introduced such as: the passage to a continuous survey, the implementation of CAPI/CATI instead of PAPI for interviews, better adherence to the international definition of employment, the change of the age limit in the definition of the unemployed (74 years old), and the data were revised back till the third quarter 1992.
