These freely accessible files data and without confidentiality issues (data and metadata) contain anonymised records, processed and prepared in a way that the observation unit can’t be identified directly or indirectly. They are free and are according to the principle of statistical confidentiality and personal data protection. Access to PUF is made on INE Portal page and implies the prior acceptance of the conditions of use.
