  2. Rules for handling confidensiality • The Statistical Act § 2-6 imply that Statistics Norway as a • main rule do not publish tables with less than 3 units within a group (table cell) where the sample can lead to identification of individuals. • At the moment this applies to population statistics, where average age is only shown for grid cells with more than 4 inhabitants. • When combining different geographical information for the unique grid cell, problems with confidentiality may increase further. The grid might for example be combined with for instance digital municipal borders or a digital road network which will give information on where the cells are located. • Main source: Geir-Harald Strand and Vilni Verner Holst Bloch. 2009.
