A transparent approach to practical evidence.
The finder helps users understand both what a city did and how much confidence to place in the available public evidence.
Scope
The public beta includes city-led or city-relevant initiatives with a defined health connection and an accessible public source. It is a curated finder, not a systematic review or a complete inventory of urban health action.
Evidence classes
Measured outcomes
The source reports observed changes in health, exposure, behaviour or another defined outcome.
Promising evidence
Available findings indicate beneficial effects, but study design, maturity or transferability limits certainty.
Process evidence
The source primarily documents delivery, reach, participation or an intermediate output.
Theory informed
The intervention has a plausible evidence-informed pathway, but outcome evidence is not yet available.
Verification
Verification is recorded separately from evidence class. “Verified” means the public details have been checked against the cited source. “Partially verified” identifies a record where some claims or classifications still need confirmation.
Limits
Evidence classifications simplify complex studies. City context matters, reported outcomes may not transfer directly, and absence from this beta should never be read as evidence of ineffectiveness.
