Methods to preserve confidentiality when publishing geographic information conflict with the need
to publish accurate data. The goal of this paper is to create a European geographic grid frame-
work to disseminate statistical data over maps. We propose a methodology based on quadtree
hierarchical geographic data structures. We create a varying size grid adapted to local area densi-
ties. High populated zones are disaggregated in small squares to allow dissemination of accurate
data. Alternatively, information on low populated zones is published in big squares to avoid iden-
tification of individual data. The methodology has been applied to the 2014 population register
data in Catalonia.^^^^
