Please not that in these graphs we have exclude the UK now, even for the years that they were still in the EU. this was done to make the data a bit more comparable over the years shown.
First a graph with a count of all attacks per year, split per cause (stacked bar chart).
The impact from the terrorism attacks differ. Separate graph on the number of deaths by these attacks, split between jihadist and non-jihadist attacks.
Europol also tracks the number of people arrested and convicted related to terrorism in the EU. Please note that there can be some years between arrest and conviction.
