Criminal Justice Professor Jerry Ratcliffe recently wrote an op-ed that was featured in the Philadelphia Inquirer. The op-ed looks at how crime spikes in the city every summer. Dr. Ratcliffe, Ralph Taylor and Evan Sorg have shown that for every 10-degree increase in temperature, Philadelphia s street robberies increase by about 2%. This effect is especially pronounced in places with more commercial land use and near subway stations. This information can be used to develop an evidence-based approach to the city s violence reduction strategy.
