The number of roles in Europe made up 8.8 per cent of total big data jobs – up from 4.8 per cent in the same quarter last year.

That was followed by Asia-Pacific, which saw a 2.9 year-on-year percentage point change in big data roles.

The figures are compiled by GlobalData, which tracks the number of new job postings from key companies in various sectors over time. Using textual analysis, these job advertisements are then classified thematically.

GlobalData's thematic approach to sector activity seeks to group key company information by topic to see which companies are best placed to weather the disruptions coming to their industries.

These key themes, which include big data, are chosen to cover "any issue that keeps a CEO awake at night".
