A research tool developed by PERIL to document, analyze, and visualize the global landscape of nihilistic violent extremism.
Every NVE incident plotted by month of offense or arrest. Each dot is one incident; dots stack when several fall in the same month. Hover a dot for the full record, or click to pin it open and read its sources.
The NVE Tracker provides researchers, journalists, and policymakers with a structured, searchable dataset and interactive visualizations covering incidents from 2011 to the present.
Visualize incidents geographically. Zoom from global overview to street-level detail, with tooltips and full incident profiles at each location.
Track how incident frequency has changed over time. Filter by year, date range, or incident type to identify surges and patterns of activity.
Explore how cases were resolved — guilty pleas, convictions at trial, acquittals, and ongoing prosecutions — across jurisdictions worldwide.
Filter incidents by country or region to support comparative analysis across 42 countries and understand local patterns within a global context.
Access data on group affiliations, military or law enforcement backgrounds, number of perpetrators, and demographic information where available.
Categorize incidents by crime type — successful attacks, foiled plots, weapons offenses, hate crimes, material support, and more — with detailed summaries for each.
Search across incident descriptions, locations, and group names to quickly surface relevant cases for targeted research queries.
Download the filtered dataset as a CSV file for use in your own analysis, research publications, or briefing materials.
Access the full interactive dashboard to search, filter, map, and analyze the complete NVE incidents dataset.
