Connecticut police collect and report highly detailed data on traffic stops that are being used by researchers at Central Connecticut State University's Institute for Municipal & Regional Policy to try to identify racial profiling practices. The data is collected to comply with revisions passed in 2013 to a 1999 law, the Alvin W. Penn Racial Profiling Prohibition Act.
TrendCT has created this portal to give readers a sense of what some of the data "look like" at the statewide, police department and individual officer levels. This page shows the aggregate data for all departments across the state. You can also see profiles for each police department, and from there you can view data on individual officers in the department.
Across the state, the proportion of minority* drivers pulled over is larger than the proportion of estimated minority drivers: 31 percent of drivers stopped were minorities, while 25 percent of the estimated driving age population were minorities. This chart shows the percentage of traffic stops by perceived race of each driver. (*"Minority" is defined as all drivers not described as "white")
On a 100% scale, this chart shows how many drivers were let go with written or verbal warnings or received an infraction, a misdemeanor summons or were arrested.
This chart illustrates the share of stopped drivers by age group.
Across the state, speeding was the most common reason for pulling drivers over. Cell phone violations, defective lights and tinted windows were other reasons listed in the data.
CCSU researchers designed a series of measures to score police departments based on how much stopping practices varied from the state average, as well as gaps between population and stops to identify racial disparity. A point was assigned to a department for every threshold exceeded. Scores range from zero to nine and indicated below whenever scores were above zero. Zero indicates no sign of disparity. Any score higher than zero indicates some degree of disparity. Some departments, such as university police departments at Yale and the CSCU schools, do not correspond to towns and do not have scores.

If you don't see your town on the list, it may not have a municipal department. More than 50 Connecticut towns have resident state troopers and wouldn't be listed here.
