How we choose what to publish

A pay figure appears here only if an official or authoritative published source states it, for a stated place and date, and we have read it in that source. We record exactly what the figure includes and excludes, and the date we last checked it.

We do not average across sources, fill gaps with estimates, project figures forward for inflation, or convert currencies. The only calculation on this page is the percentage change within each table, which we label as ours.

Pay is revised regularly. If you are deciding between real offers, the current notice or contract in front of you is the authority, not this page.
