Where these numbers come from
Reading these figures
The figures on this page come from one named vintage, stated below, and are annual values for all ownerships combined. Where QCEW withheld a value, the marked figure is an estimate that DTG produced under the constraints of the published record; suppression is a property of QCEW, not of DTG, and a withheld value is marked rather than silently omitted. Two things DTG itself holds back, and says so where it does: an estimate that cannot be given a reliability score is not shown, and average pay is not shown where fewer than three jobs are reported. The row is marked withheld, with the reason in a note beneath the table. The mark is on every row that carries a value: the headline, the yearly history, the subsectors and the other states. An estimated value that rounds below one is shown as less than one, not as zero. Quarterly figures, county figures and projected years are in the app.
How this figure was built
Employment is the average of the three monthly counts in each quarter, averaged across the year, and establishments are averaged across the year the same way. Average annual pay is the year’s total wages divided by that average employment. Each of these is DTG’s value: QCEW’s published figure where QCEW disclosed it, and DTG’s estimate, marked, where it did not. How withheld values are estimated, and what the reliability score beside a figure means, are described on the industry data and disclosure and provenance pages.
