Understanding wage percentiles
A reproducible process for reaching a narrow conclusion without losing source definitions or dates.
Read the 10th, 25th, 50th, 75th, and 90th percentiles as points in an estimated wage distribution.
A useful worksheet for “Understanding wage percentiles” begins with four boxes: definition, numerator or observed value, comparison value, and date. Fill each box directly from a primary publication. If one is empty, pause before drawing a directional conclusion.
Check comparability by reading across rather than down: same occupation or legal test, same geography level, same time basis, and same unit. Means, medians, percentiles, employment counts, benefit ceilings, and statutory floors answer different questions even when they appear in adjacent columns.
Run a red-team pass focused on assuming a percentile predicts one person’s pay without experience, industry, and location context. Rewrite any sentence that turns a survey description into a promise, a ceiling into an expected payment, or an agency summary into advice for a particular dispute.
The final note should tell another researcher exactly where to look: publication name, table or topic, code or jurisdiction, period, URL, and date checked. Preserve suppression and “not available” markers because they are findings about publishability, not defects to conceal.
For this specific task, repeat the principle in operational form: Read the 10th, 25th, 50th, 75th, and 90th percentiles as points in an estimated wage distribution. The source record should make it impossible to confuse the intended measure with the failure mode—assuming a percentile predicts one person’s pay without experience, industry, and location context. Document why the chosen field answers the question before sharing the result.
