Sectoral estimates rely on unweighted statistics (data are not adjusted for the representativeness of the respondent firm) and company data aggregated at the most detailed NACE Rev. 1 level enabled by national sampling designs and Eurostat’s data disclosure rules. Sectoral coverage varies across countries and tabulations may rely on a subset of countries and not be fully representative. Rankings rely on the same set of variables in CIS4 and CIS6 to ensure consistency and comparability over time.
