Every job, and which industries do it

How tied a job is to an industry is measured here, not asserted. The 2021 Census counts employment by occupation and by industry, so for every job we can say what share of the people doing it work in each of the twenty sectors. A payroll officer appears in nineteen of them; a schoolteacher in one. The interesting cases sit in between: software developers are just over half in professional services, which is another way of saying that most businesses in most industries have no IT department and buy that work in.

The published cross-tabulation stops at the sector, so a job's sector is measured and its industry-group tag is judgment — written only where the measured data already shows the job is concentrated, and labelled UNVERIFIED wherever it appears. 116 of the 162 carry one.
