New approaches in georeferenced statistical data and related confidentiality issues
17-10-2019 | STATEC


According to the recent EU Regulations, the National Statistical Institutes of the EU Member States have the obligation to provide some demographic variables of the 2021 EU Census at a 1 km² grid level. The publication of such geographically detailed information requires an appropriate data protection methodology in order to reduce the risk of disclosing information on individual statistical units.


Therefore, STATEC has established a new methodology which allows the provision of statistics at a 1 km² grid level while complying with the rules of statistical data confidentiality. The aim of this paper is to outline some statistical disclosure control (SDC) methods using the dataset of the current Registre des Bâtiments et des Logements of the STATEC as an example.
