Since 2020, the COVID-19 pandemic and government measures to limit its spread have had a huge impact on society. Crime opportunities and criminal justice systems have also been affected by this health crisis. With the aim of international collaboration, a working group within the European Society of Criminology has been created to promote research among European researchers and thereby facilitate the exchange of information and comparative studies on the impact of COVID-19 on crime and criminal justice systems. Thus, the School of Criminal Justice of the University of Lausanne has undertaken a mapping of the ongoing projects related to COVID-19. The aim of this research is to identify, using different keywords, all current projects carried out in English, French, German, Spanish or Portuguese. To be selected, the project had to (1) focus on the impact of COVID-19 on different areas of criminology, (2) be carried out in one of the five languages mentioned, and (3) be conducted by a legitimate research organization. Our results highlight the research question, the time periods and geographical areas covered, and the methodologies used. In total, the keywords chosen were able to report on 68 projects in progress in various fields of criminology, such as prisons, policing, domestic violence, or cybercrime.
