A Cartography of the Effects of Disclosure Control on Small-scale Population Grids in the Context of Municipal Data Requirements in Northwest Germany

Population grids, especially in rural areas, are vulnerable to the effects of statistic disclosure control methods. The paper proposes a way to map those effects and create awareness for users involved in the creation of those data sets. To achieve this, the difference between unaffected and protected grid cells is calculated and is being visualized. The effects of spatial aggregation and level of attribute details are being compared.
