"The US Crisis Monitor — a joint project between ACLED [Armed Conflict Location & Event Data Project] and the Bridging Divides Initiative (BDI) at Princeton University — collects real-time data on these trends in order to provide timely analysis and resources to support civil society efforts to track, prevent, and mitigate the risk of political violence in America.
