The report documents the technical procedures for data enrichment, pseudonymization, and risk mitigation for re-identification. Linking spatial indicators to survey data based on residential addresses may pose a risk of re-identification of respondents. Prior to linking, the dataset is processed in such a way that no combination of spatial indicators corresponds to fewer than five addresses. The analysis of uniqueness reduction is performed at the address level to prevent individual traceability. The methodology described forms the basis for further spatial analyses based on pseudonymized survey data.
