In Italy the Labour Force Survey (Lfs) follows a rotating sample design where households participate for two consecutive quarters, then they temporally exit for the following two quarters, and finally come back in the sample for other two consecutive quarters. Therefore, 50% of the households, interviewed in a quarter, are re-interviewed after three months, 50% after twelve months, 25% after nine and fifteen months.
According to the rotation scheme all the members of the households, who were interviewed in different time periods, can be matched in order to obtain longitudinal data. In particular, individual records can be matched to produce 12months and 3months longitudinal data which is almost 50% of the total sample.
Although the main product of the Lfs is cross-sectional data, longitudinal data is an essential aim for achieving a complete picture of signiﬁcant economic phenomena of labour market mobility.
Starting from aprile 2016:
- longitudina data are produced for each quarter;
- population reconstructed according to the census results and the revision of the Registries by the municipalities in the post-census period are considered for their production;
