Limitations and reproducibility

Documented: Each quote links to its primary source and an archived copy; quote-notes gives the page or location of each.

• Outcome measures do not always match the promise's wording (for example, units purchased vs. units open); each forecast's note explains the mismatch.
• Some outcomes are self-reported by the government that made the promise.
• Promises made only in news interviews or reported only by the press are excluded, so the list is not exhaustive.
• Homeless counts changed method in 2015, 2017 and 2022.
