Changes of classification in continuous statistics: Calculation of retrospective series. Application to the Quarterly Labour Cost Survey

Doc: 03/2010

A change in the system of classifications of a statistic produces new estimations that are not comparable to the previous ones. Frequently it is desirable to provide temporal series of the results with a temporal horizon enough to allow its analysis, and that's why it is necessary to elaborate retrospective series in the new system. This document tries to explain the procedure applied to adjust the estimations about Labour Costs in Spain to the new National Classification of Economic Activities (CNAE09), that is the spanish version of the EU Classification of Economic Activities, NACE rev 2
