Output harmonisation
Article 6
1. In order to facilitate Union-wide comparability, the output data values to be disseminated shall be harmonised. To this end, preference shall be given to numerical values over special values as far as possible. 2. In order to ensure sufficiently accurate and reliable information on the spatial distribution of the total population, Member States shall respect the following requirements: (a) data items on total population shall not be reported as confidential; (b) data items on total population with an observed value other than ‘0’ shall be marked with the flag ‘populated’; and (c) data items on total population with an observed value ‘0’ shall not be marked with the flag ‘populated’.
