This is a list of sources for quantitative information on jihadist terrorism. It is an updated version of the list I posted in May last year.
It contains five new sources, and working links for everything (over half had broken).
Some of the links go directly to tables or charts, but most go to articles or reports that contain the dataset within. Most of the linked articles are in PDF format.
The sources are divided according to whether they focus on individuals involved in jihadism (usually covering demographic characteristics) or on jihadist incidents (covering things like methods of attack). Those that include both have been placed in the individuals section.
Within those categories, they are divided into whether they are free or behind paywalls.
A special note is made if the data is disaggregated. Those ones don’t simply say “45% of the sample was born in the US” but provide lists of each individual or incident, with specific details. These ones are the most valuable.
If you know of any good ones I’m missing, please let me know.
