Exposure to AI

This occupation sits in the middle third of the 774 occupations scored, with an exposure score of -0.38. The scores are standardized across those occupations, so 0 is the average and a score of 1 is about one standard deviation above it.

Our note on reading it: the dataset links AI applications to the abilities that occupations require, so the score reflects overlap between the two. It is a comparison between occupations, not a forecast about jobs. It does not say whether exposure means tasks are replaced or workers get more done with the tools, and it says little about one employer or one role.
