A test of racial disproportionality in traffic stops conducted by the Greensboro Police Department
Recent research has generated questions regarding the Greensboro Police Department’s (GPD) use of race as a proxy for criminal behavior. For example, a recent New York Times article highlighted the racial disproportionality in traffic stops in Greensboro (LaFraniere & Lehren, 2015). Critically, these kinds of analyses typically use census population estimates to establish a benchmark for the driving population. Census estimates, however, demonstrate only where people reside and serve as a poor proxy for the actual driving population. Therefore, census population cannot accurately measure the population at risk (i.e., the driving population that is likely to be involved in a traffic stop). RTI International conducted a series of analyses to address this methodological limitation. This research was funded internally by RTI to serve the community and to contribute to a growing body of scientific research on this topic.
