Note: Each bubble represents an occupation (ESCO Level 4), the color of the bubble is based on an occupation group (ESCO Level 1), and the size of the bubbles corresponds to the demand (number of job postings) for that occupation in 2018. The downward sloping trend line indicates that the change in the index between 2014 and 2018 was higher for occupations with a lower digital index in 2014. In this chart, only occupations with at least 1200 job advertisements in both 2014 and 2018 were used.
