Form

Multidimensional tables

If a combination of indicators is selected for a multidimensional table which is not created, the following message is displayed: No records found.

If the combination of selected dimensions in a particular territory returns zero values (0), then these records are not displayed.

The category “remaining” always represents the sum of all categories except the selected ones. The total sum of the selected values of the variable with the value "remaining" always gives 100%.

The category “confidential” includes data that have been modified in order to eliminate the risk of identifying residents.

Territorial breakdown

Territorial units for statistics (NUTS)

STU

The territorial unit for statistics is a territorial unit for statistical purposes to provide comparable data within the European Statistical System and for analytical purposes. It relates to the implementation of the Regulation (EC) of the European Parliament and of the Council No. 1059/2003 on the establishment of a common classification of territorial units for statistics. A distinction is made between regional territorial units for statistics (NUTS) and local administrative units for statistics (LAU).

NUTS

Regional territorial units for statistics (SR=NUTS1, areas=NUTS2, regions=NUTS3).

LAU

Local administrative units for statistics (districts=LAU1, municipalities=LAU2).

When displaying data at the regional level, it is possible to analyse all or selected territorial units or only one territorial unit.
When displaying data at the local level, only one territorial unit can be analysed each time. At this territorial level, the aspect of being able to combine more content dimensions was given priority over the territorial aspect.

Data protection

Multidimensional tables including sensitive data have been protected. For this reason, the data in the protected multidimensional table, which the user aggregates from lower territorial units to higher, may differ statistically insignificantly from the data directly displayed in the multidimensional table at the level of higher territorial units, where data protection was not necessary.
