 For reference year 2016, several methodological improvements have been applied to the Structural Enterprise Statistics, framed within the 'Project for the integration of structural economic surveys'. As a consequence of these changes, the results of said exercise are not strictly comparable to those of other years, as the evolution of the variables obeys not only to possible real changes produced in this period, but also to the effects of the methodological improvements on the estimation of said variables. This effect is more pronounced for the variable number of enterprises in the Trade and Services Sectors, and relatively small for the rest of the information. 
 For more details, please consult the specific document 'Measuring the effect of methodological changes in Structural Enterprises Statistics 2016':
