Treaty status is sourced directly from the UN Treaty Collection, the UN Secretary-General’s own public record as depositary. Each treaty page shows when it was last scraped, since status changes over time — see the untreaties project for the original scraping approach this one builds on. This project is created and maintained voluntarily, on a personal basis, entirely non-commercial, and not affiliated with or endorsed by the United Nations.
Part of a family of four sites: GA Speeches (every UN General Assembly general debate speech since 1946) · UN Votes (every General Assembly and Security Council vote since 1946) · Treaty Tracker (signature, ratification and withdrawal status of major multilateral treaties) · Human Development (UNDP Human Development Index for every country, 1990 to latest release).
