Reference excerpt

The Quarterly Census of Employment and Wages (QCEW, aka ES-202) is a program of the Bureau of Labor Statistics in the US Department of Labor that produces a comprehensive tabulation of employment and wage information for workers covered by state unemployment insurance (UI) laws, as reported to state workforce agencies (SWAs) and the Unemployment Compensation for Federal Employees (UCFE) program for covered federal workers. ES-202 is the old name and stood for Employment Security Report 202. Unemployment Insurance tax reports provide the data for federal QCEW data, which is considered a statistical universe file of the employment data collected for the nation, but gig workers (e.g. in the platform economy) are typically classified as independent contractors and therefore not included in those or other federal data.

Worked examples

Example 1 — a first encounter with Quarterly Census of Employment and Wages

Start with the simplest possible case. Write down what Quarterly Census of Employment and Wages claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In mathematics, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Quarterly Census of Employment and Wages before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Quarterly Census of Employment and Wages ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.
