title: Archival Version

description: This project is concerned with understanding the determinants of racial bias in police traffic stops and in the city of Syracuse, New York. Using an officer-level panel of data on vehicle stops and vehicle searches by 512 officers from 2006 to 2009, the primary goal of this research is to better understand the effects of officer experience on their proclivities for racial bias in traffic stops, while controlling for officer, citizen, and neighborhood demographics. Included in these data are variables for census tracts as well as their racial and ethnic makeup, times and dates when traffic stops occurred, sunrise and sunset data for the City of Syracuse, and the racial and ethnic makeup of citizens involved in stops.

description: A pre-existing officer-level panel of data on vehicle stops and vehicle searches by 512 officers from 2006 to 2009 was used for the analysis. The census data utilized are publicly available 2000 census data for Onondaga County in New York. These data are used to determine which tracts are considered "black tracts." Offenses data were obtained from the Syracuse City Police Department. These data are used to determine which tracts are considered "high crime" areas. Stops data were obtained from the Syracuse City Police Department. Time data came from the United States Naval Observatory's website.
