A new batch of traffic stop data and new tools to explore it were released Tuesday by the Connecticut Data Collaborative and the Institute for Municipal Regional Policy.
There’s increased questioning of whether police officers target drivers based on their race, ethnicity, or gender. In context, Connecticut is one of the few states in which law enforcement agencies are required to submit regular updates on all traffic stops. It’s important that such specific data be analyzed and understood by the public, policy makers and civil rights groups.
The Connecticut Data Collaborative now offers several entry points for those interested in the traffic stop data:
- Their data portal, where visitors can query specifics, such as time, type, age and town.
- A data story explaining more intricate details of the statistical analysis conducted by the Institute at Central Connecticut State University using data visualizations such as maps, charts, and infographics.
- Visualizations comparing last year’s data with the new batch of data.
Here are a couple of examples they created:
Next, the Collaborative said they plan to create more visualizations to compare post-stop data, an interface that allows exploration of descriptive measures, and a drilldown on individual officers.
What we’ve done
Here at TrendCT, we’ve generated several stories using the previous version of the dataset, but there’s room for much more analysis and creativity:
