- Texas: Racial Profiling Data Analysis Study: Final Report for the San Antonio Police Department. John .C Lamberth. December 01, 2003.
"The methodology employed in this study is one that has been employed in several studies across the country. This methodology employs what we believe to be the only appropriate benchmark for such an analysis: a measure of the driving population in the local area. This study addressed the following questions: Is there evidence of racial profiling in San Antonio? Which minority groups (i.e., Blacks and Hispanics), if any, are targeted? In which locations is profiling likely to occur? Are there special circumstances that might be interpreted as biased policing?" - Ohio: "Police Vehicle Stops in Cincinnati: July 1 - December 31, 2001". "John E. Eck, Lin Liu, Lisa Growette Bostaph". October 01, 2003.
"This document is the report describing our analysis, findings, and conclusions regarding the level and causes of disproportionality in police vehicle stops. It is important to note here that a finding that African-Americans are disproportionality stopped by the police does not, in and of itself, imply any particular cause. This report is divided into six sections. The first section describes the sources of data and the analytical approach taken by the research team. The second section describes the characterstics of the people stopped by the Cincinnati Police from July 1 through December 31, 2001 in Cincinnati. The third section examines reasons for the stops, as recorded by police officers. In the fourth section, we look at the level and geographic distribution of racial disproportionality in police vehicle stops. The fifth section examines the results of stops, or the sanctions given to citizens stopped by the police. The last section summarizes our findings and describes our conclusions regarding the level of disproportionality and its causes." - Missouri: 2003 Annual Report Missouri Traffic Stops. Missouri Attorney General's Office. September 22, 2003.
"On August 28, 2000 the Missouri state legislature passed Section 590.650, RSMo (2000). This law requires all law enforcement agencies statewide to report data on all traffic stops and submit them to the Attorney General's Officer by March 1st of each year. This policy also requires that the Attorney General to report the findings to the Governor by June 1st of each year. The law also enables the Governor to withold state funding to agencies if they do not comply with the law." - Minnesota: Minnesota Statewide Racial Profiling Report: All Participating Jurisdictions.. The Council on Crime and Justice and the Institute on Race and Poverty. September 22, 2003.
"During the 2001 legislative session, the Minnesota legislature enacted Minnesota statute 626.951, providing for a racial profiling study. Persuant to this statute, law enforcement agencies throughout the state were given the option of participating in the study and those that did were at least partially compensated for the cost of participation, and received additional the purchase and installation of video cameras in their police vehicles. Sixty-five jurisdictions chose to participate, comprising 31 city police departments, 33 county sheriff's departments, and the Leech Lake Indian Reservation." - California: A Study to Analyze Traffic Stop Data in Santa Cruz County. Cheryl A. Rickabaugh. September 01, 2003.
"The chief officers of the five Santa Cruz County Police Departments came together to work through and develop a strategy to measure whether profiling was occuring in the County and how to address it if it was. To this end they began collecting data in 2002 on each of the stops that their officers made. ...they contacted Lamberth Consulting to assist in the...analysis." - North Carolina: The North Carolina Highway Traffic Study. "William R. Smith, Donald Tomaskovic-Devey, Mathew T. Zingraff, H. Marcinda Mason, Patricia Y. Warren, Cynthia Pfaff Wright, Harvey McMurray, C. Robert Fenlon". July 21, 2003.
"The North Carolina Highway Traffic Study is a multi-method investigation of the phenomenon popularly referred to as "driving while black," or more generically as "racial profiling" and "racial targeting." This project combines demographic analyses, highway observations, surveys of citizens, focus groups with drivers, and focus groups with North Carolina State Highway Patrol troopers to develop methodologies to estimate racial disparity in traffic stops, identify plausible mechanisms producing those disparities, and learn more about the consequences of perceptions of racial dispairty in policing for trust in the police. The research is intended to answer four basic questions: 1) Do NCSHP troopers stop minorities, particularly African Americans, on the road at higher rates than they do whites? 2) Once stopped, do African Ameircan citizens and white citizens experience different rates for citations, written warnings, and searches? 3) What factors might account for highway stops? And 4) How do African Americans and other ethnic minorities esperience and respond to traffic stops?" - Rhode Island: Rhode Island Traffic Stop Statistics Act Final Report.

Howard Greenwald. January 03, 2003.
"Data presented in this report are based primarily upon records of 24,451 vehicle stops completed by the Sacramento police officers during a year-long study period.
