Glossary:Micro Data Linking (MDL)

<Micro Data Linking (MDL) is a statistical method for combining data available for individual entities. Entities may be enterprises or persons or, also, a combination of the two.

In official statistics, it has become a strategic approach for exploring new informative needs (for example, globalization and green transition) without increasing the statistical burden on respondents.

MDL may use traditional statistical sources - for example, data collected with surveys already conducted in the member states under the European regulation - but also new data collections, such as administrative sources available in the member states or, as a promising future perspective, the vast amount of big data emerging from private-sector data sources.

National Business Registers (BR) of enterprises represent the crucial statistical infrastructure for implementing MDL techniques in the European Structural Business Statistics. They provide the necessary linking keys that uniquely identify the unit of interest – the enterprise - in the various business domains of interest.
