evidence: This report updates CCJ’s previous studies of crime changes that began during the early months of the coronavirus pandemic, extending the analyses with data through June 2024. The 39 cities included in this study were selected based on the availability of data at the time of data collection in early July (see the Appendix for full list). They range from Syracuse, NY, the smallest, with about 142,000 residents, to New York City, the largest, with more than 8.4 million residents. The mean population of the cities for which crime data were available is approximately 810,000, while the median population is roughly 480,000. [...] 1 Efforts to compile crime data continued through July 12, 2024. Cities that had not posted full June 2024 crime data on their websites by that date could not be included in this report. [...] This study provides up-to-date U.S. crime trends for fewer than 40 cities—a sample limited to large and medium jurisdictions that have consistently reported monthly data over the past six years. While it provides key analyses to advance understanding of current trends, it is not an adequate substitute for timely, accurate, and complete crime data on a much larger scale. In April 2023, the Council on Criminal Justice convened a panel of expert producers and consumers of crime data, the Crime Trends Working Group, to explore changing crime patterns and propose ways to improve the country’s crime data infrastructure. The Working Group’s deliberations produced consensus on multiple areas for urgent action by federal, state, and local agencies, recommendations that were published in June 2024 and can be found here.
