Esri Terrorist Attacks Storymap.

In recent years, an increasing number of terrorist attacks have shocked communities around the world, and many of the worst attacks have occurred in countries like Nigeria, Kenya, Somalia, and Bangladesh, as well as in war-torn locales like Iraq, Syria, and Afghanistan.

The Terrorist Attacks Storymap, a collaboration between Esri Story Maps and PeaceTech Lab, uses crowdsourced data from Wikipedia to present a chronology of terrorist attacks around the globe. Wikipedia moderators include experts in the field of global conflict and terrorism, and the pages driving this story have been revised thousands of times since the start of 2016. As a result, the quality of the data on this map is constantly improving.

As with any crowdsourced data, the map may display spurious or objectionable data, for which Esri and PeaceTech Lab hold no responsibility. Similarly, the definition of terrorism is subjective and, in the case of this map, is determined by the contributing community.

If you dispute an event or observe grammatical errors or misspellings, we encourage you to submit revisions to Wikipedia via the “Improve the Map” button in the About section of the map. You can learn more about the Wikipedia editing process here.
