Europe was the fastest growing region for artificial intelligence (AI) hiring among railway industry companies in the three months ending June.

The number of roles in Europe made up 13.5% of total AI jobs – up from 6.3% in the same quarter last year. That was followed by North America, which saw a -1 year-on-year percentage point change in AI roles.

The figures are compiled by GlobalData, who track 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 artificial intelligence, are chosen to cover "any issue that keeps a CEO awake at night".

By tracking them across job advertisements it allows us to see which companies are leading the way on specific issues and which are dragging their heels - and importantly where the market is expanding and contracting.
