Regulation (EC) No 223/2009 on European statisticsstipulates the need to establish common principles and guidelines ensuring the confidentiality of data used for the production of European statistics and the access to these confidential data with due account

for technical developments and the requirements of users in a democratic society.

Data are not disseminated at a level of detail where problem of statistical confidentiality could arise.

The collection of micro-data is considered as confidential. For this reason micro-data is stored and processed in a secure environment.

After the aggregation process, tourism demand data is in principle not confidential.

However, to avoid the publication of figures which are statistically unreliable, an estimate shall not be published if it is based on fewer than 20 sample observations.
