Evidence stage
DeploymentAn employer has put it into production. Can move the baseline — weighted by scale and how similar the setting is.
Tasks this bears on
Processing and coding data
Cleaning, editing and classifying responses so that they can be counted, such as coding written answers into occupations and industries.
Automating✓ Evidence-backed
Quality assurance and methodology
Checking estimates for errors and breaks, setting error tolerances and documenting methods.
Being augmented✓ Evidence-backed
Where this applies
Canada. Agency staff report that machine-learning coding of industry, occupation and class of worker was successfully implemented in the Labour Force Survey production process in October 2021; comparing 13,665 published estimates produced with and without it, they observed no breaks, and they expect machine learning to shift the nature of manual coding work. The agency's own symposium paper.
What this means
A national statistics office moved survey coding to machine learning only after statisticians checked thousands of estimates for breaks.
What it does not yet show
One agency, one survey.
What you can check
Open Statistics Canada's symposium paper 'Need for Speed' (release date 5 November 2021) and find "13,665 estimates compared".
Does it change the assessment?
No. The impact index is never moved by a single event. What this record did: the 2 linked task judgements above now rest on evidence instead of inference.
