Found a bug? Spotted an outdated tax bracket or a median rent that hasn't kept up with reality? Have a city you want added?

The fastest path is email: hi@cityparity.com

A few specifics that help:

• Data corrections. The source you're comparing against (e.g., "OECD tax database 2026" or "Numbeo as of last week") goes a long way. We cite sources per row, so we can usually figure out where the drift is.
• City requests. The more demand we see across emails for the same city, the higher it goes on the list. A sentence about why you're thinking about it helps.
• Calculation looks wrong. A screenshot of the inputs you used is the fastest path to diagnosis.
• Press or interview. Mention the angle in the subject line and we'll prioritize.

This is a small project, run by one person in spare time. Replies happen, sometimes within a day, sometimes a week. Don't take silence as dismissal; the email is checked.
