What kind of figure this source publishes

The BLS category is a relative rank, not an absolute level, and it is not a first-hand measurement: it groups an occupation's percentile ranks across several published studies into four bands. It is not an employment or wage forecast, not a probability of adoption, and it does not separate automation from augmentation.

ESCO occupational vocabulary

Each entry below is matched to this occupation in the published ESCO-O*NET Crosswalk (version 1, 2022). The match types are that crosswalk's; the wording is AI Changing Work's.

  • metal rolling mill operatorESCO 8121.5This occupation is broader

    Metal rolling mill operators set up and tend metal rolling mills designed to form metal workpieces into their desired shape by passing them through one or several pairs of rolls in order to decrease the metal's thickness and to make it homogeneous. They also take into account the proper temperature for this rolling process.

  • plastic rolling machine operatorESCO 8142.11This occupation is broader

    Plastic rolling machine operators operate and monitor machines to produce plastic rolls, or to flatten and reduce the material. They examine raw materials and finished products to make sure they are according to specifications.

  • mechanical forging press workerESCO 7221.4Overlapping, not the same

    Mechanical forging press workers set up and tend mechanical forging presses, designed to shape ferrous and non-ferrous metal workpieces including pipes, tubes and hollow profiles and other products of the first processing of steel in their desired form by use of preset, compressive forces provided by cranks, cams and toggles at reproducible strokes.

  • metal drawing machine operatorESCO 8121.4Overlapping, not the same

    Metal drawing machine operators set up and operate drawing machines for ferrous and non-ferrous metal products, designed to provide wires, bars, pipes, hollow profiles and tubes with their specific form by reducing its cross-section and by pulling the working materials through a series of drawing dies.

  • straightening machine operatorESCO 7223.22Overlapping, not the same

    Straightening machine operators set up and tend straightening machines designed to form metal workpieces into their desired shape using pressing practices. They adjust the angle and the height of the straightening rolls and select the settings for the pressing force required to straighten the workpiece, taking into account the end product's yield strenght and size, without excess work hardening.

  • swaging machine operatorESCO 7223.23Overlapping, not the same

    Swaging machine operators set up and tend rotary swaging machines, designed to alter round ferrous and non-ferrous metal workpieces into their desired shape by first hammering them into a smaller diameter through the compressive force of two or more dies and then tagging them using a rotary swager, a process through which no excess material is lost.

  • thread rolling machine operatorESCO 7223.24Overlapping, not the same

    Thread rolling machine operators set up and tend thread rolling machines designed to form metal workpieces into external and internal screw threads by pressing a thread rolling die against metal blank rods, creating a larger diameter than those of the original blank workpieces.

  • upsetting machine operatorESCO 7223.25Overlapping, not the same

    Upsetting machine operators set up and tend upsetting machines, primarily crank presses, designed to form through forging processes metal workpieces, usually wires, rods, or bars, into their desired shape by having split dies with mulitiple cavities compress the workpieces' length and hereby increasing their diameter.
