About the research

The Post-Dispatch analysis included five years of traffic stop data which more than 700 law enforcement agencies are required to file with the Missouri Attorney General’s Office. The information includes detailed statistics on numbers of traffic stops, citations and warnings issued by each agency. To create the citation rate per person, the number of citations was compared to the U.S. Census Bureau’s 2007 American Community Survey population rates. Square mile measurements of municipalities recorded in the 2000 Census were used to create the ratio of traffic citations per square mile.
