The following classification is used for data availability at Eurostat level:

The term "not applicable" relates to the categories of data which do not exist in national legislation/administrative procedures and therefore such statistics cannot be issued.

The term "not available" relates to categories of data that exist in the national legal/administrative system but cannot be delivered under EIL data collection for various reasons (e.g. data cannot exist, data exist but are not collected, data are unreliable, etc.).
