SIQual, Istat’s information system on quality, contains information on Istat’s primary surveys and secondary studies, as well as on activities carried out to ensure the quality of statistical information.
The system allows to browse the metadata describing the production process and its features: information content, survey phases and operations, activities to prevent, monitor and evaluate sampling and non-sampling errors.
In SIQual, primary surveys, secondary studies and statistical information systems are generically referred to as statistical processes.
General, but also specific documentation is available in the Documents area of the system.
SIQual also allows to access the online release of statistical data, if available.
