Data Sources & Licenses

Where our data comes from, the licence each source carries, and how we attribute it.

Data without guarantee — always verify against the official source before relying on it.

How we source data

We prefer official government and copyright-exempt sources, and aggregate, filter and explain public information — we do not claim to be an official body. Facts (rates, dates, numbers) are not copyrightable; where a source needs attribution (e.g. Creative Commons), we credit it below and link the licence. Proprietary rankings (QS, Henley, U.S. News) are not reproduced — we link out to the publisher instead.

Frequently asked questions

Is RICHBAY.ORG an official source?

No. RICHBAY.ORG is not a government site. We aggregate and explain public information and link to the official sources; always confirm on the authority's own page before acting.

Why don't you show QS or Henley ranking numbers?

Those rankings are proprietary products of their publishers and are not derived from official government data. We link out to the publisher rather than reproduce their figures, and build our own value on official public sources instead.
