What happens next
A follow-up record is a promise to look again. Evaluators revise their estimates as new studies, costs and monitoring data come in. Keeping a dated copy of what the Happier Lives Institute said lets anyone see, later, whether the estimate held up.

How you can tell it hasn't changed
Each record carries a fingerprint: a code calculated from every word and number in it. Change a single character and the fingerprint changes. Each record also carries the fingerprint of the one before it, so the records form a chain, and editing any earlier record would break every link after it.

What this record is not
- It is not a measured result. It records what the Happier Lives Institute estimated, and when.
- It is not our rating. We don't score charities; the figure is the Happier Lives Institute's, copied exactly.
- It does not change any ranking. Follow-up records are kept separately from the pages that list charities.
