摘要：This paper was inspired by some changes in the criteria for being entitled to subsidies in Norwegian agriculture, and the changes this induced in agricultural statistics. Although the paper is concerned with Norway only, the Norwegian experiences might be of interest to a broader audience. It illustrates some of the challenges which can occur when statistics is based on register data, and the register owner make changes in the criteria and thus in the information gathered.
