Text: The current inquiry adds to the body of knowledge in this area by exploring potential changes to both reactive and proactive officer activities brought on by the pandemic using CFS **data** from Houston, Texas collected from January 1, 2018 through December 31, 2020. This study is informed by routine activity theory and perspectives on proactive policing. Trends are examined for seven different call types: violent crime, property offenses, disorder incidents, suspicious incidents, traffic-related activities, service-related activities, and non-crime events. In doing so, observed trends can be compared to the other large jurisdictions to further our understanding of how the pandemic has impacted demands for police services (e.g., Ashby, 2020). We also examine trends in officer proactivity through officer-initiated activities identified in the CFS **data** performed by three units: patrol, specialized crime investigation units, and the department's specialized response unit. This provides a unique look into how COVID-19 may have influenced officer-initiated activities.<|eot_id|><|start_header_id|>assistant<|end_header_id|>
