When publishing population characteristic frequency tables for small geographic areas, such as in a census, it is usual that some cross-tabulations would be disclosive in some areas but not in others. Areas with higher diversity in person characteristics lead to more tables being non-disclosive. We describe a new computer language for codifying rules that decide whether an output table is disclosive for each geographic area. The publication rules are written in this language by the statistical disclosure control professionals and input into a flexible dissemination software system. The rules can thus be unknown to the programmers of the software system.
