Data Visualisation of Occupations / Work Activities, Competences and Skills / Abilities

The two links below show Sankey diagrams for the linkages in O*NET between Occupations / General Work Activities, Competences and Skills /Abilities.  All data is taken from O*NET release 25.2 (Feb 2021), which features the new Standard Occupational Classification SOC 2009.

Notes to the Sankey diagrams:

  1. The O*NET data model contains no entity called ‘competence’, but a broad equivalence is made here between the generally-used meaning of competence (ie. proficiency in carrying out a work function) and the O*NET entity Intermediate Work Activity (IWA);

  2. In O*NET, IWAs are aggregations of occupational tasks – see the O*NET data model for more information and see here for our description of how we used the data model for this project;

  3. The visual depth of the nodes in the Sankey diagrams are non-significant in terms of importance, but are merely related to the count of the individual link between each node;

  4. The Sankey diagrams open in a new browser tab.


General Work Activities -> Competences (IWA) -> Skills / Abilities

Occupations (O*NET) -> Competences (IWA) -> Skills / Abilities


The data used for the Sankey diagrams relate to a small subset of O*NET occupations which BMI assesses as being a) important to Knowledge and Digital economies and b) potential target occupations for bachelor and/or masters graduates in interdisciplinary studies.  These occupations have in turn been broadly mapped to the following data elements:

  • (green columns): Graduate level occupations with the highest levels of employment (in excess of 100,000) in the UK. The occupation titles used are from the UK SOC coding system at the 4-digit level and cover a range of different job titles (source: NOMIS);

  • (orange columns): A sample of graduate destination jobs from historical interdisciplinary bachelor-level courses (source: LIS);

  • (blue columns): O*NET occupations used for the Sankey diagrams.
