Contact & corrections

We read every message. Correction reports are the fastest way to improve the site: tell us the page, the figure, and the primary source you checked, and we re-verify the baseline before the next weekly build. All mail goes to hello@officialcost.com.

Report an incorrect or outdated figure

This site is fully static and stores nothing you type. Submitting the form opens a pre-filled message in your own email app addressed to hello@officialcost.com; nothing is sent until you press send there.
