Every public figure on RoleMath traces to an official source. This page lists those sources, what we use each one for, and how current it is. We do not invent data and we do not cite sources that are not on this list.

How current the data is
Update cadence and freshness: pay data from BLS OEWS is released no more often than annually; BLS employment projections are released no more often than annually; O*NET is updated periodically and not continuously; official vendor certification pages are re-checked periodically. Each source carries a last-verified date so you can see when we last confirmed it. None of these sources is a live, real-time feed, so we do not present any figure as a live or guaranteed-current number.
What these figures mean (and don't)
Important framing: all pay and outlook figures are occupation-level context from BLS and O*NET, and they are not personal figures. They describe an occupation across the whole economy. They are not a salary you are promised, not a per-credential earnings figure, and never a personal guarantee, and no wage shown here is a number you are owed.
