Earlier this month, the FBI released the national-level crime statistics for 2021. According to that data, violent crime, particularly murder, remained a major issue in the United States. Crime remained relatively consistent from 2020 to 2021 with no statistically significant changes between years, though violent crime was still elevated compared to 2019 levels. From 2020 to 2021, national levels of violent crime decreased slightly (-1.0%), largely driven by decreases in robbery (-8.9%). Murders, however, increased (+4.3%). The data is available for download via the Crime Data Explorer, or it can be accessed using a new tool called the Law Enforcement Agency Reported Crime Analysis Tool (LEARCAT). But the data this year may be lower quality than years past, limiting our ability to draw inferences about national-level crime rates.
Policymakers and researchers rely on these data to understand state and national crime trends, but that may be more challenging this year. Unfortunately, the FBI’s plan to modernize its reporting of crime data has not gone according to plan, so it’s hard know how accurate these 2021 estimates are. The new system has advantages over the old system, but it is much more cumbersome and time-consuming to use, which has negatively impacted law enforcement agencies’ willingness to submit their data. And because of these low participation rates, there are huge gaps in nationwide crime statistics for 2021.
