Codes and Frequencies
Most IPUMS data transformations are performed using variable harmonization tables that specify how each value in the source data is recoded. Some variables also require programming logic in addition to the harmonization table. The harmonization documents for this variable are:
GEO2_IT identifies the household's province (referred as metropolitan city code in Labor Force Surveys) within Italy from 2014 to present. Provinces are the second level administrative units of the country, after regions. GEO2_IT is spatially harmonized accounting for political boundary changes across years. Some detail is lost in harmonization; see the comparability discussion. A GIS map (in shapefile format), corresponding to GEO2_IT can be downloaded from the GIS Boundary files page in the IPUMS International web site.
The full set of geography variables for Italy can be found in the IPUMS International Geography variables list. For cross-national geographic analysis on the first and second major administrative level refer to GEOLEV1, and GEOLEV2. More information on IPUMS-International geography can be found here.
Comparability — General
Where boundaries changed over time, units were harmonized to create units with boundaries that remain stable over time. There were several boundary changes in between provinces within the Sardegna region.
Samples from 2014 to 2020 are Labor Force Surveys. Information on provinces are not included in the 2011, 2012, and 2013 Labor Force Surveys as well as the census samples.
