Research from Stanford University Data and More from Stanford's Cutting Edge Researchers

Exploring this Exhibit

This collection includes research outputs from Stanford-associated researchers on the wide variety of topics and fields under investigation at Stanford University, including statistics, engineering, biology, chemistry, social sciences, humanities, medicine, physics, geosciences, and the environment. This content is made discoverable and accessible via deposit into the Stanford Digital Repository (SDR). You can find out more about the SDR service and federal funding agency requirements for data sharing and preservation on the About page.

SDR Deposit of the Week: the Stanford Open Policing Project



On June 19th 2017, the Stanford Open Policing Project launched its website to provide access to the data collected about police stops around the country and to provide information about research that this data is driving. Stanford Libraries is pleased to be a partner in the long-term preservation of this data, which has been deposited into the Stanford Digital Repository (SDR). The persistent uniform resource locator (PURL) for the "standardized" stop data is archived as a national repository of state patrol stops in the SDR. The value of putting the files into an institutional repository such as the SDR insures the longevity of access to the data for continued and future use by researchers and journalists alike.

The Project

Since 2014 Stanford researchers in the Stanford Computational Journalism Lab, led by professor Cheryl Phillips, have been working in collaboration with Sharad Goel, faculty in the Stanford School of Engineering, to gather and analyze U.S. police stop data from 31 states. This past weekend, at the Investigative Reporter and Editors (IRE) conference in Arizona, Phillips presented on this project. Stanford researchers have looked into racial disparities related to stop outcomes and search outcomes within the data collected and have started to publish their findings. This data set was compiled by making public information requests from local, county and state police departments. The team of researchers at Stanford who helped to garner, clean and analyze the data include Vignesh Ramachandran and the graduate students, Emma Pierson, Camelia Simoiu, Jan Overgoor, and Sam Corbett-Davies. Of the 31 states that provided the data requested, 20 states provided highly detailed data. Standardizing the data was an important step that allows researcher to start looking at state-by-state comparisons.
