As the number of ESCO implementers increases, the range of uses of the classification is widening. The ESCO dataset is currently employed by public and private implementers as the reference language for employment and education, being widely recognised as the dictionary for the European labour market. However, implementers might not always look for something as granular as ESCO skills or occupations, as they may prefer smaller-sized and aggregated datasets which are easier to handle for their own purposes.

Thus, the European Commission aims to unravel the complexity of the ESCO dataset through more dynamic illustrations of how ESCO concepts can be connected and used at more aggregated levels. In those  documents, the Commission is showcasing potential interrelations (defined as matrix tables) based on the hierarchical structure offered by the ESCO and ISCO-based hierarchies (for both skills and occupations). The ESCO Skill-Occupation Matrix Tables accessible below, allow users to connect ISCO-08 occupation groups (rather than one single occupation) to ESCO skills hierarchical groups (rather than one single skill). Starting from the most granular level of the ESCO classification, these tables show the share of ESCO skills within ISCO-08 occupation groups.
