About tidycops
Harmonized police data for cross-city research and analysis.
tidycops is an R package designed to make it easier to work with and compare public police incident data across multiple US cities. Instead of navigating different data portals and APIs for each city—some use Socrata, others ESRI or CKAN—you can use the same R functions to pull incident data consistently.
The package provides comparable, harmonized fields across cities for direct comparison, while also giving you access to all source-specific fields when you need the complete picture. With flexible queries, a simple interface, and support for 25+ cities, tidycops makes cross-city police data analysis practical and accessible.

We'd love your feedback
This package has been a labor of love and we'd love feedback from folks who use R regularly. If you're interested in testing the package with your own research, requesting additional cities or data fields, reporting bugs, or suggesting improvements—please try it out and share your thoughts!
We tried, where we could, to bridge gaps in data sources across years. Test all the things and suggest all the features. If you see your city in the list above and want to give it a go, please do and tell us why it works or what needs improvement.
