It’s Too Unreliable to Tell (The Marshall Project) Nearly 40% of law enforcement agencies around the country did not submit any data in 2021 to a newly revised FBI crime statistics collection program, leaving a massive gap in information sure to be exploited by politicians in midterm election campaigns already dominated by public fear over a rise in violent crime.

- Using Open Web-based Crime Data for Research: A Word of Caution - Research Note." International Journal of Social Research Methodology 24, no. 6 (2021): 767-73.

This paper describes available web-based crime mapping services and discusses some of the key advantages and disadvantages of using this source for both general purposes and scholarly endeavors. Using a research project on crime occurring around train stations as a case study, we illustrate the pitfalls of relying on web-based services compared to requesting crime information directly from law enforcement agencies. We conclude with a few cautionary remarks regarding the use of data services that purport to offer an assemblage of crime data drawn from different jurisdictions.
