Reducing Violence by Transforming Neighborhoods: A Natural Experiment in Medellín, Colombia
evidence
Supports the statement that neighbourhoods served by Medellín's first Metrocable line and associated investments showed larger declines in violence than comparable control neighbourhoods, using a longitudinal resident sample and prosecutor homicide records. V55 verification basis: retrieved as an abstract listing and secondary summaries; the article was not opened, and effect sizes quoted in circulation differ, so no single percentage is asserted here.
A evidence is not a place. Drawing it on a map would assert something about the world that no stored fact supports.
